摘要

针对金华电厂燃气-蒸汽联合机组DCS存在的控制继电器接点容量小、高压开关控制接点的脉冲时间长、发电机并网同期点性能较差、DEH伺服卡抗静电能力差及控制软件组态缺陷等问题

提出了解决方法。

Abstract

Directing against problems existing in DCS of the gas and steam combined cycle unit in Jinhua Power Plant

such as small capacity of contacts in control relay

long pulse time of control contacts in high-voltage switch

worse performance of synchronizing point for closing the generator into grid

bad antistatic capability of DB-1 servo-card

and defects in configuration of control software etc.

some solving methods have been put forward.
