turbine over-speed protection

Described are advantages of motor-driven pipeline booster compressor over gas turbine-driven pipeline booster compressor in environmental protection and economy.

论述电动机驱动管道增压压缩机比燃气轮机驱动具有环保和经济两方面优势，是一种发展趋势；

It becomes the main role of turbine control system. It includes DEH ( Digital-Electro-hydraulic Control) and AEH ( Analisys-Electro-hydraulic Control). In this paper, an over-speed protection control system is developed.

在电超速保护控制系统中，又可分为模拟电液调节系统和数字电液调节系统（DEH，Digital Electro-hydraulic Control），本课题及开发数字电液调节系统中超速保护装置。
