N125汽轮机DEH电液接口的安全性分析及其改进技术

合肥发电厂3^#,4^#机组原调节系统为国产典型的旋转阻尼式,现改造成DEH控制系统.针对改造中的DEH系统电液接口的安全性问题,采取了一些改进技术,取得了良好效果.这些改进技术可供其他机组改造时借鉴、参考.;Hefei Power Plant's no.3 no.4 turbine regulation systems used to model roll zuli regulation system made in China.Now,it has been reformed into DEH control system.Some improment techniques are adopted to solve the DEH electric connection's question.The question's improvement techniques may be a reference for the reformation of other generation turbine
