摘要
变电站所用电系统是确保变电站安全可靠运行的重要部分,其设计方案、设备选型对变电站安全运行的可靠性影响较大。通过对2个变电站室内所用电系统的设计分析,对比国网公司所用电典型设计,提出了目前所用电设计存在的问题,并从简化设计、优化设备选型,便于运行维护等方面提出了变电站室内所用电设计的改进方案。
Due to the important role of the self-demand system in the safety and stability of substation,its design scheme and device selection have great influence on the stability of substation operation.Through the analysis of self-demand systems of two substations,combined with the typical design of self-demand system of State Grid Corporation,the problems existing in design are put forward.In addition,the design scheme of self-demand system in substation is proposed from these aspects,such as simple design,device selection optimization and easy operation and maintenance and so on.
