A quick overview of the AVR V2 excitation system
The ALSPA P320 AVR V2 is a digital excitation systems designed by Alstom® with functions like stator voltage control, field (excitation) current control in manual mode, limiters, field flashing, droop and some options like PSS, reactive power control, power factor control, line charging, boosting …
The standard configuration is two redundant channel:
2 Automatic Voltage Regulators channels with integrated Field Current Regulator, with or without connection to a supervision (F8000, Modbus …)
AVR V2 PLC and cards
It mainly consists of GE® Fanuc Series RX3i cards, CPU 310, ALG220, ALG391. Some specific electronic cards have been produced by Alstom:
- UMT162: Universal Measurement Treatment module, performs:
- Stator voltage and current acquisition
- Active power, reactive power, PF calculation
- TTM210/TTM211: Thyristor Triggering Module receives the Uc signal (firing angle) sent by the AVR and elaborates the firing pulses for the thyristors.
- TPI163 : This card interfaces the VT and CT secondaries with UMT 162 card
- Other cards like IEX164, BEM340, TPA 213, TPC 215, TPT 214 can be used according options and applications.
AVR V2 Local Control Panel and maintenance tools
Local Control Panel (LCP): RedLion Company product name G306A
The LCP allows the operators and technicians to modify parameters, and operate the AVR locally. Tests can also be performed from the LCP for commissioning.
ControCad™ (CCAD) is the full package which allows to modify and compile the AVR program. It also allows to record the signals through the “evlog”, these are capture blocks that are triggerd manually or on a signal level.
