Application Research of Sequential Quadratic Programming in Fault Location of Traction Networks
摘要
Abstract
Existing research on short-circuit fault location in traction networks typically focuses on reducing model errors.However,there are currently two major problems:the lack of a unified standard for model solution methods,which makes it difficult to effectively compare errors from different models;insufficient robustness in the solution methods,due to their intelligent algorithms that increase solution errors.To address these issues,this paper focuses on short-circuit fault location in DC traction networks and AC direct power supply traction networks.Based on the establishment of corresponding fault location models,the Sequential Quadratic Programming(SQP)algorithm is introduced to solve these models.Simulation testing results show that the SQP algorithm yields distance measurements with improved accuracy and robustness.Additionally,this algorithm provides a solution paradigm to evaluate model performance based on error levels.关键词
