Abstract

Most of the breakdowns and malfunctions of the electrical and control systems inside or in the vicinity of a wind turbine due to lightning are caused by a rise in ground potential. To solve those problems, the field tests have been carried out, and the transient characteristics of an actual wind turbine grounding system have been obvious. This paper describes the verifications of field tests of wind turbine grounding characteristics by using the Finite Difference Time Domain method.

用时域有限差分法测量风力发电系统暂态接地阻抗的验证
风力涡轮机内部或附近的电气和控制系统因雷击而发生故障和故障,大多数是由地电位上升引起的。为了解决这些问题,进行了现场试验,得到了实际风电机组接地系统的瞬态特性。本文介绍了用时域有限差分法对风力机接地特性进行现场试验的验证。
