Abstract

Abstract:

Aiming at the problem of large capacity reactive power causeol by the extensive use of cable lines in urban power grid,the automatic switching method of combined standby power supply based on hot standby line is put forward.The automatic switching devices on the power supply side and on the load side are quipped.By combining the two devices,the substation’s capacitive reactive power is solved and the voltage level is improved.The occurrence of large-scale blackouts can be effectively avoided when the main supply line is permanently faulty,the self-healing of power grid can be realized and the power supply reliability can be improved.

Key words: urban cable, capacitive reactive power, hot spare line, combined automatic backup power supply
