摘要
针对矸宁线路的2种送电方案,即在线路的宁格尔侧或矸石侧进行空冲线路操作,利用RTDS实时数字仿真平台对矸宁线在送电方式、正常运行方式及检修方式3种工况下线路的工频过电压、合闸操作过电压和单相重合闸操作过电压进行实时仿真分析。试验结果表明,2种送电方案均满足工频过电压和操作过电压的限制要求,其中从宁格尔侧比从矸石侧空充矸宁线的合闸操作过电压低,相对安全。
In connection with two schemes for electric power transmission in Gan-Ning power line,that is,to conduct line loop operation by charging unloaded lines from Ninggeer Township side,or from Ganshi Township side,real-time simulation analysis of power frequency overvoltage,closing operational overvoltage and single phase reclosing overvoltage has been carried out,by three working conditions of power transmission mode,normal operation mode,and maintenance mode to Gan-Ning power line,using RTDS simulation platform.Testing result shows that electric power transmission two schemes can satisfy requirements of power frequency overvoltage and closing operational overvoltage,in which,operational overvoltage is lower with conducting of line loop operation by charging unloaded lines from Ninggeer Township side than that of Ganshi Township side,and safety relatively.
