微机远动系统在无人值班旧站改造中的应用

摘要

肇庆电力工业局结合本局实际，采用了一种无人值班旧站改造的实现方式，即利用DMU-2000分布式微机远动系统实现。对DMU-2000系统的构成、设计思想、与保护控制回路的配合等方面作了详细的论述。这一方式在生产实践中发挥了很好的作用。%Combined with the real conditions of Z haoqing Electric Power Bureau, an implementary scheme is adopted for the unmanne d substation retrofitting,which uses the DMU-2000 microcomputer-based distribu ted remote control system.The system str u cture, design concept, and cooperation with different kinds of protection's cont rol circuit are described in detail. The scheme is playing a good role in the pr oductive practice.
