Analysis And Improvement Of Steam-Turbine Control System

The role of steam turbine in the steam of high pressure spins with high speed. The control system has guaranteed that voltage and frequency stabilize , have guaranteed in electrical network appearance fault or unit the safety that arises fault opportunity group self.Along with the raising of parameter and the increase of unit capacity, it is more and more complex to start and run, the safety of unit also becomes more and more important The mechanical regulating system of fluid pressure type that adopts always can not be already complete to satisfy the requirement of production, especially the generation set of large scale power plant.The four departments generation set of 360 MW power plant from French ALSTOM by Huaneng Luohuang Power Plant, its steam machine control system , including steam machine regulation and steam machine protection system are designed by French GEC-ALSTOM DEM company. Because this control system is popular in China , therefore is necessary to discuss this control system , refer to and popularize for its good qualities.This paper analyze the steam turbine control system of Huaneng Luohuang Power Plant,have introduced the major characteristic of control system. Additionally, according to the actual experience of scene, this paper has also been concerned with the improvement of control system as well as the handling for fault.
