D-AVR TOSATEX3000 |
Application:
D-AVR system can be applied to Static excitation system and Brush-less excitation system, and to many other existing excitation systems in operation also.
Improved monitoring:
- In Toshiba's DCS and EHC delivery, network transmission and surveillance control by OPS are realized.
- HMI (Human Machine Interface) and IES (Integrated Engineering System) based on Microsoft® Windows® 2000
- Standard interface (RS232C Modbus, TCP/IP Ethernet, etc.) with external systems
Automatic generator voltage build up:
Generator voltage is built up and reaches the rated voltage automatically, only by energizing the closing signal of the generator field circuit breaker.
High quality:
Wide experience and good results in the field around the world
Full Redundancy:
From inputs isolation circuits for the direct A/D conversion to phase control and gate pulse generator
Full Control Functions:
AVR, UEL, OEL, VPFL, PSS, MEC, CCC, etc.
High Accurate and High speed direct digital A/D converter with Filter of high harmonic frequency :
0.2% accuracy, 16bit resolution
High Speed Processing:
5msec control period
Simulator:
Generator system simulation software program is included in the controller for test and training.
Improved Maintainability:
- Transient data record : Transient control response confirmation and failure analysis
- Self diagnostic function
Visual monitoring / touch operation:
- Status of generator operation
- Alarm display
Best approach for power plant control system:
Toshiba provides a wide range of technical support based on wide experience in power plants through basic engineering to equipment installation and commissioning. Toshiba's experience covers both conventional plants and combined cycle plants.
