摘　　要：现有配电网安全域的研究都是由配电网得到其安全域。首先研究了由安全域逆向生成配电网拓扑的问题,介绍了配电网安全域的基本概念;其次,借鉴网络综合的思想,提出了由安全域解析式逆向生成配电网拓扑的方法,所生成的网络能够全面反映安全域特征;再次,对N-0安全域和N-1安全域,通过算例验证了所提方法的正确性,算例分析表明,由N-0安全域不能生成唯一网络,由N-1安全域能够生成唯一网络;最后,探讨了所提方法的应用前景。Since most of the existing researches on distribution system security region(DSSR)generate their security region from a given network,the problem of reversely generating the distribution network topology from its security regionis studied in this paper for the first time.First,the basic concepts of DSSR are introduced.Second,a reverse topology generation method for distribution network from the analytical formula of security region is proposed by combing the idea of network synthesis,and the generated network can fully reflect the characteristics of DSSR.Third,the correctness of the proposed method is verified by case studies for N-0 and N-1 security regions.Results show that the N-0 security region cannot generate a unique network while the N-1 security region can generate a unique network.Finally,the application potential of the proposed method is discussed.
