【摘要】 电力系统发生特大事故可能导致电网解体为数个孤网,并使一些发电厂断掉了和系统的联系成为孤岛,如何迅速恢复孤网间的联网及孤岛电厂的快速再入网,是电网安全运行必须考虑的问题,也是被瓦解的电力系统有效实施黑启动所必须面对的现实。枢纽变电站配置快速、精确的同期装置已成为当今电力系统必须解决的问题。更多还原

【Abstract】 Serious accidents of power system may make power grid disaggregated into several isolated networks and make some power plants become "isolated islands" due to disconnected with power system.How to rapidly recover the power network connection between isolated networks and connect system of isolated plant again? It is the problem that must be taken into account for secure operation of power grid.In the meantime,it is the fact that must be faced with for collapsed power system to effective implementation of black start.The configuration of rapid and precise synchronizer for hub substation has become the problem that must be solved for current power system.更多还原
