【摘要】 介绍了金华地区电网110 kV旁母应用现状及扩展应用的情况,针对地区电网某些薄弱环节,在主设备重载或设备检修时,提出利用110 kV旁母转供的新运行方式,并分析了继电保护配合方案,降低了电网运行风险,提高了电网供电能力和可靠性。该方法已多次在金华电网应用,取得了很好的效果,可为其他地区电网提供借鉴。更多还原

【Abstract】 The current application of 110 kV bypass buses in Jinhua local grid is presented,as well as extended application of them.To deal with some weak links in the grid,the new operational method is proposed,in which the 110 kV bypass bus is used to supply loads when the main equipment is heavily loaded or during maintenance.The relevant relay protection schemes are also analyzed.The extended application of 110 kV bypass buses reduces grid operational risks and improves the supply ability and reliability of the grid.Practice in Jinhua grid proves the method effective.更多还原
