风电场集电线路自适应继电保护系统设计研究

Research on the Design of Adaptive Relay Protection System for Wind Farm Collecting Lines

文章重点研究风电场集电线路自适应继电保护技术,从集电线路现有阶段式过电流保护和集电线路现有零序电流保护两方面详细总结了线路保护存在的问题,并对集电线路自适应继电保护系统进行优化设计,设计内容具体包括系统架构、程序结构、数据库设计、硬件设计等,以期为风电场的稳定运行提供有效参考。

This paper focuses on the study of adaptive relay protection technology of collector line in wind farm,summarizes the problems existing in line protection in detail from the existing stage overcurrent protection of collector line and the existing zero sequence current protection of collector line,and optimizes the adaptive relay protection system of collector line.The design includes system architecture,program structure,database design,hardware design,etc.,in order to provide an effective reference for the stable operation of wind farms.
