摘要/Abstract

摘要：

风电场的接地不但要满足工频短路电流,还要满足雷电冲击的要求。如果风电场的接地装置设计存在缺陷,会造成系统振荡、设备烧毁、全场停运甚至人员伤亡等严重后果。发变电站接地系统的参数评估是电力系统设计的重要环节,进行准确细致的接地网参数仿真计算是非常重要的。本文开发的风电场接地设计软件主要采用数值计算方法,能够较为全面地考虑实际影响因素,为风力发电场的设计、建设和运行提供有效的帮助。

Abstract:

The grounding of wind farm should not only meet the demand of power frequency short-circuit current, but also meet the requirements of lightning impulse current. If there are defects in the design of the grounding device of the wind farm, it will result in the consequences of system shock, equipment burning, the suspension of the whole field and even personnel injury. The parameter evaluation of the grounding system of the transformer substation is an im-portant part of the design of power system, and it is very important to carry out accurate and detailed simulation calculation of grounding grid parameters. The wind farm earthing design software developed in this paper mainly adopts numerical calculation method, which can consider the influence factors in the actual situation more com-prehensively and provide the help for the design, construction, and operation of wind farm.

Key words: High soil resistivity, wind power plant, earthing design software, parameter simulation, numerical calcula-tion method
