Description

T8431C | ICS TRIPLEX | Fieldbus control system module

With the rapid development of the power T8431C in China, DCS is also being used more and more widely. However, DCS mainly completes the automatic process control of steam turbines and boilers, with less automation integration of the electrical part. DCS generally does not fully consider the control characteristics of electrical equipment, so there is a big gap between DCS and the network microcomputer monitoring system in terms of openness, progressiveness and economy, both in function and system structure.

The monitoring objects of the electrical fieldbus control system mainly include the generator transformer group, and its monitoring scope mainly includes the generator, generator excitation system, main T8431C , and 220kV circuit breaker; The monitoring scope of high-voltage auxiliary working and standby power sources mainly includes high-voltage auxiliary working transformers, start-up standby transformers, etc; The monitoring scope of low-voltage auxiliary power supply in the main plant mainly includes low-voltage auxiliary working and public transformers, lighting transformers, maintenance transformers, and dust removal transformers in the main plant; Auxiliary T8431C low-voltage plant power supply; Power supply feeder from power center to motor control center; Unit generator and boiler DCS control motor; Security power supply; DC system; AC uninterrupted power supply.
