摘要
随着电网的迅速发展,智能化变电站的应用也越来越多。但是由于智能化变电站属于新兴变电站,在应用过程中还不完善,需在设计应用过程中进一步改进。以110k V祝舜变电站为例,在验收过程中发现GIS开关事故跳闸后,保护装置所发"事故总"信号在其他保护信号复归后本信号不能复归,对GIS开关的操作回路进行研究分析,并提出二次回路改进意见。
With the rapid development of the power grid, the intelligent substation is more and more widely applied.However, as a new substation type,the intelligent substation has many problems in application whieh need further research and design. Taking the 110 kV Zhushun substation as an example,the aecldent resultant signal resets failure after other protection signals reset,the operation circuit of the GIS is analyzed,and improvement suggestions are put forward on the secondary loop.
