联合循环机组启动阶段协调控制浅析

Analysis on Coordinated Control of Combined Cycle Unit in Startup Stage

介绍了申能临港燃机发电有限公司西门子SGT5-4000F联合循环机组在启动阶段的协调控制及高旁压力、余热锅炉对燃机升负荷的限制,并对两起启动阶段升负荷异常案例进行了分析,希望为同类型机组控制逻辑分析、异常事件判断提供借鉴与帮助。

Coordinated control mode of Siemens SGT5-4000F combined cycle unit in start-up stage is introduced,HP bypass control mode in the startup stage and the influence of relevant parameters of HRSG on the load rise limit of gas turbine is described in detail.Finally,two cases of abnormal load rise in the startup stage of unit are analyzed,which provides reference and helps for the control logic analysis and abnormal event judgment of the same type of units.
