摘要

结合某电厂600 MW对冲燃煤机组辅机故障减负荷(RB)试验

对RB功能典型控制逻辑设计进行了修改。针对模拟量控制系统(MCS)在RB试验过程中暴露的高压加热器系统设计和2台一次风机效能不平衡而发生失速等问题进行分析

并采取了有效的改进措施。试验为今后类似机组RB功能的调试及其存在问题的处理提供参考。

Abstract

Combined with the situation of run-back(RB) function test for one 600 MW unit

necessary modification of the typical logic design for RB function has been carried out.Directing against problems exposed in the process of CCS test

such as design of high-pressure heater system

and "stall" of two primary air fans due to unbalanced efficacy

analysis has een carried out

and effective improvement measures being taken.The test provides with reference for debugging of related units in the future

and for solving problems existing in the process.
