摘要：【中文】本发明公开了一种保全局部电网稳定性的主动解列方法，包括以下步骤：确定重要负荷中心和主要配套电源所在的局部电网的区域边界；确定隔离局部电网的最优主动解列断面；确定需要实时监测的相关电气量；实时监测相关电气量，判断是否需要主动解列，在触发主动解列的同时触发孤岛的紧急控制。本发明能够隔离主网的严重故障影响，保障局部电网的稳定运行，最大限度减小重要负荷的损失。 【EN】The invention discloses an active splitting method for preserving the stability of a local power grid, which comprises the following steps: determining the regional boundary of a local power grid where an important load center and a main matched power source are located; determining an optimal active splitting section for isolating a local power grid; determining related electrical quantity needing to be monitored in real time; and monitoring related electrical quantity in real time, judging whether active splitting is needed or not, and triggering emergency control of an island while triggering the active splitting. The invention can isolate the serious fault influence of the main network, ensure the stable operation of the local power grid and reduce the loss of important loads to the maximum extent.
