Research on Parallel Operation Technology of Following-Setting Compensation Mode Arc-Suppression Coils

Abstract:

currently, more and more following-setting compensation arc suppression coils are applied. When the power distribution network is operated in a loop closing mode, the problems about the parallel operation of the following-setting compensation arc suppression coils are caused. On the basis that the operational characteristics of the following-setting compensation arc suppression coils are analyzed, the improved master-slaved type automatic control technology of the parallel operation of the multiple following-setting compensation suppression coils is proposed. When the capacitive current is calculated, all slave arc suppression coils should go into service with the respective compensating capacity of each when operated on the respective shunt, then the master arc suppression coil is adjusted, and therefore the calculation accuracy is guaranteed. After the calculation of the capacitive current is completed, the compensating current should be proportionally distributed according to the capacity of the arc suppression coils so that the loads of all the arc suppression coils are balanced. The technology is mature and reliable and the practicability of the technology is fully proved by the actual field operation. Chinese library classification number: TM475;TM761
