摘要

为了使二拖一燃气-蒸汽联合循环机组能够快速启、停和安全、高效运行

根据机组旁路系统的结构及特点

设计了旁路系统全程压力控制策略

解决了传统旁路控制系统存在的无法实现全程自动控制

燃机启动时间长

蒸汽大量损失

从而影响机组经济性的问题

并取得了较好的控制效果。

Abstract

In order to make the gas-steam combined cycle unit realize quick startup/stop and safe and efficient operation

the bypass system full pressure control strategy was designed

according to the structure and characteristics of the unit bypass system.Through this control strategy

the problems affecting the unit economic efficiency

such as the conventional bypass control system can not achieve full automatic control

long startup period of the gas turbine and huge steam loss

were solved.
