Section 2 Installation and connection of the controller

The BR6000 is designed to be incorporated into the front panel of a PFC-cabinet. It requires a switchboard section of 138 x 138 mm to DIN 43700/ IEC 61554. The controller is inserted from the front and is attached by means of the appended clamps. The controller may be inserted only by qualified technicians and must be operated in accordance with the specified safety regulations.

Before the BR6000 is connected up, all leads and cables must be checked to ensure that no current is flowing through them and the current converter must be short-circuited.

Care should be taken to ensure that the measuring voltage and current are in the correct phase position. The measuring-current circuit must be wired with copper leads of regulations must be observed.

The measuring voltage may lie in the range from 30 — 525 VAC and can be connected between L — N ( default ) or between L — L (programming of phase correction needed)

The operating voltage is 110…230 VAC +/- 15% and can be connected between L — N or

L -L (depending of the grid).

!

The coil voltage for the capacitor contactors and the measuring voltage must be drawn from the same phase conductor, as only the measuring voltage is monitored. (Protection against direct reconnection of the capacitor contactors in the event of momentary single-phase power failure)

2.1 Current measurement

When installing the current converter, care should be taken to ensure that the load current flows through it. The outputs of the compensation network must be installed behind the current converter (in the direction of current flow). If the BR6000 is connected up via sum-current converters, the overall conversion ratio is entered.

Current converter clamps should be grounded on one side!

Section 5 Programming

Pressing the «Operating mode” key once takes the user from automatic operation to

Programming mode. Parameter 1 ( I-CONVERTER) is reached by pressing «ENTER”.

The upper display always shows the parameter and the lower one the set value. The values are changed by pressing the é / ê keys. Subsequent pressing of the «ENTER” key stores the value and takes the user to the next parameter.

Description of the parameters: See the next page

To quit programming mode in any step, press the «Operating mode” key.

5.1. Automatic initialization

With the automatic initialization the BR6000 will automatically recognize the parameters of the PFC-system. It also serves as plausibility check and storage of these parameters — the user only has to make very little or even no adjustments.

Start of the initialization process is done from the menu point “PROGRAMMING” by

AUTO-INIT [YES] to be confirmed with pressing the ENTER button.

BILD: AUTO-INIT YES BILD: CT -UNKNOWN

If the values of the current transformer OR the value of the first stage of the PFC-system are known, they should be entered here. This later enables a display of all values of the net in the correct electrical term. If no value is programmed (selection: unknown), values of current and output can later only be indicated as percent.

After entering of the a.m. values (selection via “ é / ê” buttons,confirmation with ENTER) the automatic test-run of the BR6000 is performed.

BILD: TEST 1

3 test-runs will be performed during which all stages are being switched on and off. All necessary parameters are collected, evaluated and stored. Under certain circumstances

3 additional test-runs may be required for a proper initialization.

After successful finalization of AUTO-INIT the BR6000 will switch to normal operation.

In case of recognition of any discrepancies (plausibility) or of inaccurate connection, the detected error will be displayed in plain text after finalization of AUTO-INIT and can be eliminated. (see possible error messages at the end of the manual). AUTO-INIT may be repeated then.

NOTE: If the BR6000 has been put into operation successfully by AUTO-INIT with all values unknown, some values will be shown as “????” and this can not be changed. If a new programming is required, a reset is needed before: Programming/Basic settings

Selection is performed via the é /ê keys. Continue with ENTER

12 DISCHARGE TIME

This is the time for which an individual output is blocked between connecting and disconnecting. This blocking time has priority over connecting and disconnecting times. It depends on the capacitor discharge rating and thus is specified by the compensation network. The discharge time of a conventional network without additional fast-discharge resistors or chokes should be set to no less than 40 seconds. For setting of a second discharge time see ‘Expert Mode’ point 10

Setting range: 1 sec …20 min. Default setting: 60 sec.

Selection is performed via the é /ê keys. Continue with ENTER

13 ALARM TEMP

[ 50…85]°C

The alarm temperature programmed here is the temperature at which the capacitor stages are disconnected in steps. The controller’s alarm relay responds after ten minutes. At the same time the display shows the cause of the alarm (over-temperature). If the temperature drops again, the required branches are automatically re-connected in steps.

The selection is performed with the é /ê keys. Save and continue with ENTER.

14 MESSAGE RELAY

( available not in each type )

The message relay can be programmed for one of the following options as required:

“OFF”:

«External”:

Relay not used

The relay switches if an external input signal (110…230 VAC) is sent to the «external” input. This function may be used to directly compensate a larger load, for example — the required 40-second reconnection delay is already integrated.

Display: Capacitor symbol at the top right of the first line.

When this function is selected, the input cannot be used for the signal ‘2nd parameter set’ and the output cannot be used for the fan.

«Fan”:

(Default)

Relay switches the external cabinet fan.

The switching threshold can be programmed under point 15.

Display: «F”

Message when active power is supplied. Display: «S” «Supply»:

«Undercurrent”: This message appears whenever the measuring current is not reached. Display: «U” The signal is generated when the value drops below the response sensitivity of the controller.

27 HARMONICS (harmonic limit)

[7]% (0.5 … 25,5)%

A limit for the total harmonic distortion THD-V (in%) can be entered here. When this threshold is exceeded, a message is given. THD-V is the ratio of the geometric sum of the uneven harmonics to the fundamental. A warning is always shown in the display; an output via message relay only takes place when this was selected under point 14.

BASIC SETTING:

[ NO ] ( YES / NO )

When the selection is made with YES and confirmed with ENTER, all parameters are reset to the basic setting made by the PFC-system manufacturer.

(Optimal network values when the controller was supplied with a complete PFCsystem). If the controller is supplied from the works, this point corresponds to the default setting.

CAUTION: All user settings are lost!

5.3 Programming lock

The BR6000 is equipped with a programming lock to ensure protection from unauthorized or inadvertent changes to the system parameters. The lock can be activated in expert mode. If the lock is active, all parameters can be checked but not changed.

Section 6 Manual operation (initial operation, maintenance, service)

Programming of fixed stages

In manual operation, capacitor branches can be connected/disconnected in the set

control series and switching time — irrespective of prevailing power-line conditions.

The starting condition is STOPP (no stages connected). Connections are made by pressing the é key. Pressing ê initially leads back to STOPP mode. Repeated pressing of

ê leads to the disconnection of stages. The active operating status and active power factor are always shown on the display (self-explanatory).

Manual operation

Pressing ENTER takes the user to the menu point «Programming of fixed stages”.

In the normal case, all stages are programmed for automatic operation (default setting).

Setting of fixed stages

AUTO OFF FIX (Currently selected stage blinks)

In special cases, all controller outputs (C1 — C12) may be permanently defined in succession (continued switching via ENTER) for the following statuses:

AUTO: Automatic (normal) operation

The relevant output is marked by a capacitor symbol.

FIXED: The output is continuously connected, e.g. for fixed PFC. The output is marked by an underlined capacitor symbol.

OFF: The output is continuously disconnected — e.g. for temporarily disconnecting a defective capacitor. The capacitor symbol for this output is faded out. Underlining appears.

The active stage is blinking. The required status is set via é /ê. By pressing ENTER, the user saves this step and moves to the next stage.

The programmed statuses for the outputs also remain visible on the display in automatic operation.

After the required settings have been made, pressing the «Operating Mode” key takes the user to the next menu («Service”) or further to «Automatic Operation”.

Section 7 Service menu

The service menu is reached by the operating-mode key.

The stored maximum values of the network parameters can be displayed here as well as the number of switching operations of the individual capacitors and their operating time.

The desired stages [in square brackets] can be selected via the arrow keys.

In addition, a fault memory is available, in which the last 8 fault states of the system are stored with fault code and in plain text. (This allows, for example, capturing short lived events of overtemperature or overvoltage)

TEST-RUN

This menu point allows the user to check the settings of the PFC controller. After activation of the test run, the controller switches each stage on and off successively and calculates the output of the capacitors connected (this procedure is done three times to eliminate possible errors). The values calculated are stored and can be retrieved in the following menu item (C-POWER). At the same time, a plausibility check is conducted with the values programmed.

Any discrepancies found are evaluated and displayed in plain text. The following errors can be displayed:

— No measuring voltage present

— Measuring voltage too high — check programming

— Measuring voltage too low — check programming

— No measuring current? — Short circuit link in current transformer?

— Phase angle current transformer? k/l or phase transposed ?

— Current transformer ratio / 1. Step power wrong ?

— Control series? — check programming

— End stop? — check programming

— Capacitor defect or wrong power input

Note: The results displayed are messages intended to help the user trace the cause of the error. Final evaluation remains the responsibility of the user. Under complicated (high load fluctuations) grid conditions, 100% error recognition cannot be guaranteed.

Section 8 Expert mode 1 and 2

The expert mode is meant for the adjustment of values which normally should not be changed. As a protection against mal-operation this level has an access code branching out in Expert mode 1 or 2.

Section 9 Control principle

The control response of the BR6000 can be selected in programming mode. In principle, the controller has four different control modes:

1. Sequential connection

In sequential connection, the required capacitor stages are successively connected and disconnected in stages (last in — first out). The ranking of each step always corresponds to the power of the smallest stage.

Advantage: Exact definition of the next capacitor to be connected in each case

Disadvantage: Long settling time, high switching frequency of the small stages

In order to shorten the settling time, the BR6000 switches several stages simultaneously for a large power-factor requirement. This applies to all control types. The maximum dimensions of the simultaneously switching branches can be changed in expert mode. If the value of the smallest stage is pre-selected, the conventional sequential connection is obtained.

2. Loop connection

In this variant, the controller operates in loop mode (first in — first out) which minimizes the wear on the capacitor bank, i.e. where stages are of equivalent dimensions, the stage which was disconnected for the longest period of time is always connected next.

Advantage: Balanced utilization of equivalent stages and thus an increased operating life of the capacitor bank.

Disadvantage: This mode can only be used in control series with groups of the same stage power and long settling time, as every switching step corresponds to the value of the smallest stage.

3. Intelligent loop connection (default setting )

The intelligent control principle combines the advantages of the network-sparing loop connection (first in — first out) with a much faster settling time, even for large load skips, and reaches this goal with the fewest possible switching operations of the capacitor stages. The optimized time response is achieved by the simultaneous switching of several or larger capacitor groups as a function of the missing power factor in the power line. Both the number of real switching frequencies of the capacitors as well as the turn-on times of the branches are considered.

Advantage: Reaches the target cos phi in a fast-optimized settling time with a low switching frequency of the capacitors.

4. Combined de-tuning (special case for combined de-tuned banks)

Within a combined de-tuned application, 2 adjoining equal steps are switched with just one joint choke. This pairwise de-tuning requires an appropriate closed control series (i.e. 1:1:1:1…, 1:1:2:2…, 1:1:2:2:4:4… or similar)

The condition for the switching behavior is defined in such a way that the number of activated odd steps is always greater than or equal to the number of activated even steps. The controller complies with the requirements of the control regime while largely conforming to the intelligent switching behavior.

Section 10 Interface *(option)

The BR6000 is equipped with an RS 485 interface as an option.

It can be used to implement the following functions:

 Full parametrization of the controller via a PC

 Remote read-out of all parameters during operation and displays via a PC

Display, logging and analysis of all grid parameters with software “BR7000-Soft” (version 5) for Windows.

( see separate description of the software )

 Connection of system accessories — e.g. data-logger with RJ45 interface

 Selection of MODBUS (see Annex 5) or ASCII (see table below) for permanent display of grid parameters in ASCII format). Any ASCII editor can be used.

Using with MMI6000 e.g. for measurement of inherent current of capacitor bank or for current measuring at a long distance between CT and BR6000

The following data are permanently displayed and refreshed via ASCII (ASCII Protocol):

An individual configuration of the ASCII-protocol is possible in expert-mode 1: points 26 and following.

For the bus-connection a shielded cable has to be used!

Bus-connections (in and out) have always to be made directly to the relevant device!

In case of “point-to-point” connection the terminating resistors inside the connected devices have to be activated (DIP-switch ON).

Section 11 Initial operation

The controller must have been installed before being set up and operated.

All network-specific parameters are fully programmed as described in section 5

(Programming) by being entered in sequence and stored. The controller is then set to automatic operation with the operating mode key. It is now ready for operation.

Section 12 Maintenance and warranty

The BR6000 should need no maintenance if the operating conditions are observed.

However, it is recommended that a functional check of the controller be performed in conjunction with the regular checking of the capacitor bank. In the event of any interventions in the controller during the warranty period, all warranty claims lapse.

Application example:

Two separate PFC systems installed at two transformers; coupling and decoupling of the two transformer LV grids possible.

1) Coupler open: Both systems work completely independent.

2) Coupler closed: Due to controller coupling, the two PFC systems are operated in parallel.

This operation mode avoid an undesired mutual interaction of the PFC systems when operated at one common busbar (oscillation).

The same power in steps is switched in symmetrically for both PFC-systems.

An optimal operation will be reached by coupling two systems with the same power.

Description:

In case of this controller coupling the currents of both controllers are registered. The measured values are transferred to the “Master”, that controls and synchronizes both controllers via interface. No additional installation is necessary.

Installation:

Coupling of two PF-controller BR6000 is done via their system interface via standard LAN-cable CAT5 .

The 110…230~ signal “coupler switch closed” has to be input at the external potential free input of one controller ( will be the “Master”). This master controller has to be programmed as given here.

Annex 4: Mixed dynamical compensation system

A mixed dynamical compensation system implements economically the advantages of a dynamic fast network. (Fast changing loads are compensated dynamically and basic loads / slowly changing loads are compensated conventionally)

For designing a mixed-dynamical compensation system a special controller was developed. The BR6000-T6R6 supports up to 6 transistor-outputs (for triggering thyristor modules) and additional 6 relay-outputs for standard capacitor contactors.

Please compare the separate manual.

In case more than 6 dynamical and 6 conventional stages are required, the following application with two controllers can support up to 2x 12 outputs.

Coupling of a standard controller (BR6000-R) with a dynamical one (BR6000-T)

By coupling a BR6000-R12/S485 with a dynamic controller BR6000-T12/S485 , a mixed dynamic system (with more than 12 steps) can be designed that implements economically the advantages of a dynamic fast network.

Annex 5: Capacitor current monitoring using MMI6000

N

Application

For permanent current monitoring inside the compensation system the MMI6000 is recommended as an accessory for the BR6000. This measuring device is able to determine the sum current of the complete PFC system as well as the current of single capacitor branches.

By monitoring the current of the installed capacitors, extraordinary grid conditions (e.g. harmonic currents which may cause an overload of capacitors) can be identified. In such a case, the power factor controller switches off the relevant compensation stages as long as the extraordinary situation continues. Monitoring of the capacitor current also means monitoring of the capacitor condition

(damages, aging …) and thus gives the opportunity to avoid consequential damages.

The MMI6000 will improve the reliability and safety of a PFC-system.

Method of operation:

The MMI6000 measures the sum current inside the PFC system. For this a current transformer has to be installed at the power input of the compensation system. During each switching operation, the actual current change is measured and compared to the rated current of the switched capacitor(s). In between the switching operations the current of the complete system is monitored.

If the measured current of a step is too low (default 60%), this step is switched off. The relay is deactivated and the BR6000 display shows “E” (error) for this step. The alarm relay is activated. A reactivation of the step is possible in manual mode.

In case the current of a step is too high (default 130%), this step is also switched off. The BR6000 display shows an inverted capacitor symbol. The current is further on checked periodically is the rated current reached again, the step is reactivated.

Is the sum current of the complete PFC system too high (default 130%), stages are switched off one after another and alarm relay is set. Periodical measurements are performed to check whether the current reaches the nominal value again. If so, the step is reactivated.
