基于信度融合和滑模控制的暂态电压扰动源容错性定位
Fault-tolerant Location of Transient Voltage Disturbance Source Based on Credibility Fusion and Sliding-mode Control
摘要
Abstract
A fault-tolerant location method based on credibility fusion and sliding-mode control is proposed to automatically locate the transient voltage disturbance source (TVDS) in smart distribution networks with distributed generators (DGs) integrated.The system framework is set up first for fault-tolerant location of TVDS based on the networked power quality monitoring system (NPQMS).Then three critical function modules are realized, including power quality transient state estimation (PQTSE), credibility analysis and fusion of direction-judgment, influence rules of DG integration.Based on the theory of sliding-mode control (SMC), a novel method is proposed for automatic location of TVDS with fault tolerance.In its implementation, the direction-judgment with fusion credibility and the correction strategy for the direction misjudgment caused by DG integration have been integrated in the proposed location method.The proposed method is validated on an IEEE 34-bus distribution network with DG, the TVDS location results demonstrating the feasibility and effectiveness of the fault-tolerant location method.关键词
