ALSTOM200 MW汽轮机保护系统可靠性及其优点

Reliability and Its Virtue of ALSTOM 200 MW Turbine Protective System

针对ALSTOM汽轮机采用分散控制系统作为汽轮机保护系统,从系统配置、结构及用模拟量代替开关量等方面对其可靠性及优点进行了分析,并且与采用PLC作为汽轮机保护控制系统进行了对比,阐述了ALSTOM汽轮机保护系统可靠性以及为提高保护系统可靠性所采取的方法。

Aiming to the ALSTOM adopting the decentralized control acts as turbine protection System, analysing the reliability and merits from the system confituration, structure and using analogue quantity instead of circuitbreaker quantity and etc., and comparing with adopting PLC acted as alternator protection control system, and expoundsthe reliability of ALSTOM turbine protection system, for uplifting reliability of protective system so to adopting the way.
