| 摘 要： | 基于单种判据的小电流单相接地故障选线成功率普遍较低,提出一种基于模糊理论的综合选线装置,通过对选取的各暂、稳态判据进行隶属度函数设计,形成各判据选线结果的模糊集,通过加权处理得到完备的选线结果。在硬件方面,利用uPSD3334D的系统功能和接口能力及TMS320VC33的数据处理能力,组成双CPU系统。装置具有组网功能及友好的人机交互界面,较好地满足了配网自动化的要求。该装置已通过实验室实验并取得了较好的选线效果。

| Abstract: | Since the success rate of faulty line selection based on single criterion for single-phase earthing fault in non-solidly earthed network is normally low,a fuzzy theory based comprehensive faulty line selection equipment is proposed,which designs the membership function for each criterion to form a fuzzy set and then gets a complete line selection by weight processing.A dual-CPU system is designed,which makes use of both powerful system functions and rich peripheral ports of uPSD3334D and the powerful data processing ability of TMS320VC33.The designed equipment has networking capacity and friendly interface,meeting the requirements of distribution automation.It has been verified in lab with satisfying results. |
