【摘要】：提出了一种基于信度融合和滑模控制的含分布式电源(DG)智能配电网中实现暂态电压扰动源(TVDS)容错性自动定位方法。在基于网络化电能质量监测系统平台的TVDS容错性自动定位系统框架下,对其中关键功能模块的实现原理进行详细分析,包括基于电能质量监测点优化布置的电能质量动态状态估计、扰动方向判定信度影响因素分析及信度融合、DG接入对扰动方向判定影响规律分析与归纳。然后,提出一种基于滑模控制的TVDS容错性定位算法,实现综合考虑了扰动方向融合信度、DG接入方向误判校正的TVDS容错性自动定位。最后,通过IEEE 34节点含DG配电网络算例,分析验证了所提TVDS容错性定位方法的可行性和有效性。
[Abstract]:A fault tolerant automatic location method based on reliability fusion and sliding mode control (SMC) for transient voltage disturbance sources (TVs) in smart distribution networks with distributed power supply (DGG) is proposed in this paper. In the framework of TVDS fault-tolerant automatic positioning system based on networked power quality monitoring system platform, the principle of key function modules is analyzed in detail. It includes dynamic state estimation of power quality based on optimal arrangement of power quality monitoring points, analysis of factors influencing the reliability of disturbance direction determination, and analysis and induction of influence law of reliability fusion DG access on disturbance direction determination. Then, a fault tolerant location algorithm for TVDS based on sliding mode control is proposed, which can automatically locate TVDS fault tolerance by taking into account the disturbance direction fusion reliability and DG access direction error correction. Finally, the feasibility and effectiveness of the proposed TVDS fault tolerant location method are verified by an IEEE 34-node DG distribution network example.
