摘要
一般重要的负荷都采取双电源供电,运行中习惯选取供电线路距离较近的电源供电,另一个电源做备用.但从供配电经济运行方面考虑,则应把运行中的供电变压器损耗考虑进去,即通过对负载分别由两个变电所供电时的有功功率、无功功率和综合功率经济运行的临界负载进行定量分析,以确定变配电所供电的经济运行方式.
Important load generally employs dual power supply,the near of which is habitually selected for the power supply,another power for reservation. However,on economic operation of power supply,the loss of running supply transformer should be taken into account. Only when critical load of economic operation of each transformer is calculated quantitatively,can the economic operation mode of substation be scientifically determined.
