| 摘要: |
| 为有效解决互补约束故障定位模型缺乏多重故障强辨识能力及决策方法存在的数值稳定性问题，借鉴其代数关系建模优势，基于分层解耦策略，构建具有多重故障强适应性的配电网故障定位层级优化模型。基于松弛策略和二次规划极值理论，提出具有全局收敛特点且无需对离散变量直接进行优化决策的模型求解预测校正算法。仿真结果表明，所提模型和算法不仅能实现馈线故障区段单一和多重故障的准确高容错性辨识，且进行优化决策时具有实现便捷、数值稳定性好、优化效率高的优点。 |

| Abstract: |
| The complementary constraint fault location model lacks the strong multi-fault identification ability and has numerical stability problem in decision-making, aiming at which and drawing on the advantages of algebraic relational modeling, a hierarchy model of fault location in distribution network is proposed based on hierarchical decoupling strategy, which can effectively identify multiple fault. Based on the relaxation strategy and the quadratic programming extreme value theory, the predictor-corrector algorithm is proposed, which has global convergence characteristics and does not need to directly optimize the discrete variables decision. The simulative results show that the proposed model and algorithm can realize the high-fault-tolerant identification of single and multiple faults in the feeder fault section, and can be easily realized for optimal decision-making with good numerical stability and high efficiency. |
