中文摘要 |
本文針對以往含分散式電源的多源配電網故障定位算法定位精度低、容錯性差等缺點,提出通過一種改進的麻雀搜索算法以實現快速準確的配電網故障區段定位。首先改進麻雀搜索算法中發現者的搜索策略,然後將預警者直接向最優位置的跳躍改為向最優位置的移動,最後將其映射到離散空間中完成對配電網故障區段定位的求解。建立了含分散式電源的多源配電網模型,進行配電網故障定位類比實驗,驗證了麻雀搜索算法在多源配電網故障區段定位中的可行性。算例模擬結果表明,所提方法搜索速度快、容錯性強、精度高,具有較強的實用性。 |
英文摘要 |
Aiming at the shortcomings of low positioning accuracy and poor fault tolerance of the previous multi-source distribution network fault location algorithm with distributed generator, an improved sparrow search algorithm is adopted to achieve fast and accurate determination of fault location in the distribution network. Firstly, the finder's search strategy in the sparrow search algorithm is improved. Then, the alerter moves to the optimal position instead of jumping directly to the optimal position. Finally, it is mapped into discrete space to solve the fault location of the distribution network. A simulation model of a multi-source distribution network with distributed generator is established, and a simulation experiment for fault location of the distribution network is carried out to verify the feasibility of the sparrow search algorithm in fault location of the multi-source distribution network. The simulation results show that the proposed method has the advantages of fast searching speed, strong fault tolerance, high accuracy and strong practicability. |
