Development of Control System for Supercritical 600MW Steam Turbine Made in Domestic

摘要

Nowadays, the number of large capacity units with high parameters, especially with thin long shafts and supercritical pressure has been increased rapidly in electric network. The safety of these units will have great impact on the safety steady of the network. The stability of control system for such units receives much more attention. This paper introduces the development of control system of supercritical 600MW steam turbine made in domestic from following aspects: DEH system and oil supply system, over-speed protection system, admission mechanism and regulating mode.
