本文详细介绍了为确定G83/1型试验微型发电设备的电网断开要求所引起的开关瞬态的严重程度而开展的工作。在ATP-EMTP中建立了一个一般的家庭供电和简单的城市和农村低压电网的模型，并模拟了一系列的发电机切换操作。结果发现，在用户供电侧，高发电机输出和低瞬时家庭负荷的组合导致1.4 p.u.的过电压幅度。在配电水平，发现直接相关性存在于馈线上的发电机数量和馈线上的峰值过电压幅度之间。确定了最坏的情况设想，以供进一步详细研究，并需要对模型进行一些改进。
This paper details work undertaken to determine the severity of switching transients arising as a result of the G83/1 grid disconnect requirements of type-tested micro-generation equipment. Models of a generic domestic electricity supply and simple urban and rural low voltage networks are constructed in ATP-EMTP, and a series of generator switching operations simulated. It was found that, on the customer supply side, the combination of high generator output and low instantaneous domestic load led to overvoltage magnitudes of 1.4 p. u. At distribution level, a direct correlation was found to exist between the number of generators on a feeder and peak overvoltage magnitudes on that feeder. Worst case scenarios were identified for further detailed study, and a number of model refinements would be required.
