摘要
数字化变电站和继电保护下放是近年来电气设计的一种趋势,阐述了数字化变电站和继电保护下放的关系以及数字化变电站通过采用数字式互感器,标准的通信协议,一次智能设备等为继电保护下放创造了条件,同时介绍了继电保护下放布置的三种形式,重点描述保护下放布置所带来的取消电缆沟、扩建方便等诸多优点。从设备的抗干扰措施、电源的分配、保护小室的环境问题等方面探讨了继电保护下放带来的问题及解决的方案。
Digital substation ＆ protection decentralization is a kind of trend for the electricity designs in recent years, this text emphasized analyzes the relation betwen the digital substation and protection decentralization. Digital Substations offer such as digital transduce, the standard communication protocol and the smart device to create the conditions for protection decentralization. It introduce the three forms and characteristics of the protection decentralization and emphasizes the protection decentralization＇s benefits to reduce the cable ditch and facilitate the expansion of substation etc. It dissusses the problems associated with the equipment anti-jamming measures, equipment power distribution, environmental problems of small rooms of the protection decentralizationand and solution.
