摘要
分布式馈线自动化需要快速隔离故障并进行供电恢复,采用贪婪算法进行供电恢复,将每一路备用联络电源恢复供电的过程看成是一个子问题,把联络开关STU定义为主控STU、其他开关STU为从STU,主控STU主动识别出故障点下游的非故障区,计算出备用电源的容量,与非故障区总的负荷进行比较,从而进行最大范围供电恢复。理论分析表明基于贪婪算法的分布式供电恢复具有快速恢复供电、提高供电可靠性的优点。
Distributed feeder automation need to quickly isolate the fault and restore the power supply, the greedy algorithm is used to restore the power supply, each spare contact power supply recovery powered process as a sub problem, the contact switch STU is defined as the main control STU and other switch STU is defined as slaveSTU, master STU according to the fault isolation information and feeder topology identify non fault areas downstream of the fault point, calculate the current capacity of the standby power supply, and compared with the total load current in non fault zone , and carry out the maximum range of power supply restoration. The theoretical analysis shows that the distributed power recovery based on greedy algorithm has the advantages of fast recovery of power supply and increasing the reliability of power supply.
