摘要
分析了常规变电站站用电系统现状及存在问题,主要包括站用电源自动化程度低、系统管理和信息共享困难、投资浪费等,针对这些问题问题,阐述了智能变电站站用电源系统一体化设计的可行性;提出了智能化变电站交直流一体化技术方案,即采用网络通信、一体化监控、系统联动等方法实现站用电源网络智能化设计,并统一采集站用各子系统数据,通过一体化监控设备对整个站用电源系统进行管理,实现辅助系统的联动。并介绍了该方案在户县330 kV变电站及柳湾110 kV变电站的实际应用。
The paper analyzes the status and problems in station power service for conventional substation,based on which expounds the feasibility to design the integrated operation of the station power supplies in intelligent substation,puts forward the technical scheme for AC DC integrated system in the intelligent substations,which implements the intelligent design of the station power supplies by means of network communication,integrated monitoring and system linkage.The data acquisition system is adopted to collect all information for subsystems,and the whole station power supplies is managed by integrated monitoring to implement the linkage of auxiliary system.This paper also introduces the application of the proposed scheme in Huxian 330 substation and Liuwan 110kV substation.
