摘要
随着风力发电技术的不断发展,风电场单向接地故障导致的并网问题日益显现。本文通过对比,建议风电场中性点接地形式选用小电阻接地。通过工程实例,比较了两种典型的小电阻接地设计方案,同时对其保护配置和可靠性进行了分析。
Due to the increasingly development of windfarm, Single-phase-to-ground fault became a crucial subject. By comparison, this article suggests that the neutral ground selection in windfarm should be small resistance grounding. Also review and reliability analyses of two typical small resistance grounding design are showed.
