    • Distributed power generation systems generally comprise a number of power sources and electrical power loads interconnected by a distribution network. Electrical switches and fuses are provided such that local groups of power sources and power loads can be established. Should there be a degradation in the distribution network in terms of a set of criteria such as electrical frequency, current or voltage then the switch or fuse may be thrown to establish each local group as an island. By monitoring divergence from a set of criteria a method and controller may be utilised whereby the distribution network as a whole is considered and configured to establish virtual islands which operate prior to the establishment whether inadvertently or deliberately of actual islands within the distribution network. In such circumstances the transition from normal operation for the distribution network to islanded operation for the distribution network is less severe.
    • 分布式发电系统通常包括由分配网络互连的多个电源和电力负载。 提供电气开关和保险丝,以便可以建立本地的电源组和电源负载。 如果分配网络在电气频率,电流或电压等一组标准方面出现降级,则可能会抛出开关或保险丝以建立每个本地组作为岛屿。 通过从一组标准监测分歧,可以利用方法和控制器,从而将分配网络作为整体被考虑并配置成建立虚拟岛,其在建立之前操作,无论是无意或故意地在分布网络内的实际岛屿。 在这种情况下,从分销网络正常运行到分销网络孤岛作战的过渡不那么严重。
