【摘要】 简介了全分布式控制网络构成的水电厂微机监测系统的结构、功能和故障诊断系统。它不仅能实时监测机组运行参数，且可对事故做出快速反应，大大提高了水电厂安全运行水平。由于网络采用总线拓扑结构和真正的全分布方式，因而在老电厂的技术改造中，不仅运行可靠、抗干扰能力强，且布置安装简便，投资省。更多还原

【Abstract】 A brief introduction is given about the structure. function and fault diagnosis system formed by overall distributed controlled network in hydroelectric plant. It can not only monitor the operation parameters of power unit on real-time, but also give quick reaction to the faults, so it may heighten the safety operation level of the power plant. As the network is formed by general line topology structure and real overall distributed pattern,it is reliable on operation, sturdy on anti-interference, easy to install and low on cost.更多还原
