摘要:

对国内外风电接入后对电网继电保护的影响问题进行了综述。分析了不同类型风电机组的故障特征、短路电流特性以及影响风电场短路电流的因素。分别论述了风电接入对送出变压器、送出线路以及配电网继电保护的影响。基于风电接入系统继电保护的性能，总结了风电接入系统继电保护存在的不协调问题及相应的解决方案。建议后续研究应基于风电场的低电压穿越特性加强风电系统故障特性研究，重视风电场自动控制系统和电网继电保护与安全自动装置的配合，研究机组保护与风电场保护、系统保护之间的协调配合，全面解决风电系统继电保护面临的问题。

Abstract:

A survey on relay protection for grid-connected wind farm at home and abroad is given. The fault characteristics and short-circuit currents characteristics of various types of wind turbine and wind farm as well as the factors impacting short-circuit current of wind farm are analyzed; the influence of wind farm integration on outgoing transformer and outgoing transmission line and the power distribution network protection is discussed; based on the performance of relay protection of wind power access system, the problems of relay protection non coordination in wind power system and the corresponding solutions are summarized. It is suggested that the researches in four aspects, such as solution to the low voltage ride through capability of relay protection and matching problems, strengthening the fault characteristics of wind power generation sets, paying attention to the coordination of the automatic control system of the wind farm and power network relay protection and safety automatic device, studying the coordination and cooperation of the protection of wind farm, to comprehensively solve the problem in the face of relay protection. This work is supported by National Natural Science Foundation of China (No. 51267019 and No. 51467019).

Key words: wind farm protective relaying electromagnetic transient short-circuit current fault characteristic
