准东地区电网为新疆大型能源基地,目前该区域大用户较多,且均配套建设相应的自备电源,造成电网短路电流问题突出. 对准东区域电网短路电流现状进行了详细的分析计算,结合准东电网"十三五"发展规划分别从电网运行方式调整、加装串联电抗器、电源转接3个方面对短路电流的下降情况进行详细的分析. 计算表明:解决电网短路电流的根本措施为分散电源接入,合理分配750 kV变电站的电源装机容量.

Zhundong power grid is the power base of Xinjiang autonomous region .With the connection of so many self -provid-ed generators to the power grid , short-circuit current problem becomes more and more severe .The current situation of short-circuit current in Zhundong power grid is analyzed in detail .Three methods are introduced to lower the short -circuit cur-rent in Zhundong power grid , that is, adjusting operating mode of power grid , installing series current -limiting reactors and transferring the self-provided generators to a new power substation .The results show that the most effective way to solve the problem of short-circuit current is to disperse the generators and make sure the capacity of generators to one substation should not be too large .
