A Novel Fault Section Location Model With Complementarity Constraints and Its Optimization Algorithm for Distribution Network
摘要
Abstract
Fast and exact feeder fault location method plays an important role in enhancing reliability and self-healing of distribution network. In order to overcome the numerical optimization instability and low decision-making efficiency of logic relationship based indirect fault location method, a novel complementarity constraints fault location model was proposed based on algebra relationship and complementary theory, which advantage lies in: 1) avoiding the fault identification model excessive reliance on swarm intelligence algorithm in optimization computation, in which the gradient algorithm with good numerical stability can be used; 2) complementarity constraints conditions based relaxation method was used to relax the discrete variable for continuous variables equivalently, which reduces the complexity of fault location problem. To solve the novel model effectively, the hybrid solution method was put forward on basis of smooth theory with disturbance factor. The simulation results show that the proposed method based on smooth theory and nonlinear programming, not only can realize the accurate identification of the feeder fault section and has high fault tolerance performance, good numerical stability and high optimization efficiency, which has a good application prospect in future.关键词
