摘要

为了使火电机组在事故消除后快速带负荷

对在全自动控制方式下机组停机不停炉功能的实现方法进行研究

针对制约全自动控制方式下机组停机不停炉功能的因素进行了分析

并对控制策略进行了优化和完善。以菲律宾MARIVELES燃煤电站2×330MW机组为对象

在全自动控制方式下进行停机不停炉功能试验。结果表明

优化后的控制系统能够满足机组甩负荷(FCB)下停机不停炉功能的要求

可全程在线投入停机不停炉功能。同时

验证了配置70%及以上容量旁路系统的机组可在安全阀不开启的情况下实现FCB停机不停炉功能。

Abstract

In order to make the thermal power unit be loaded as soon as possible after the fault was eliminated

the method to realize turbine tripping without boiler shutdown was investigated

in fully automatic control mode.After analyzing the factors affecting this function

optimization and improvement on the unit control strategy was conducted.Taking two 330 MW units in Philippines Mariveles Coal-fired Power Plant as the object

experiments about this turbine tripping without boiler shutdown function was performed in fully automatic control mode.The results show that

during fast cut back(FCB)process

the optimized control system can meet the requirements of turbine tripping without boiler shutdown.At the same time

it was also verified the turbine tripping without boiler shutdown function was available under condition with the safety valve closed for units equipped with bypass system owning capacity of 70% and above.
