为满足电力用户对供电可靠性的要求,近年来国家电网公司加快了“坚强电网”建设步伐,特别是主网已基本满足N-1的要求,这为变电站设备检修提供了有力支撑。对于单主变终端变电站,传统的分设备、分间隔、分电压等级的检修方式已不能完全适应形势发展的需要,引入多元化检修方式是当前检修管理的需求。
In order to meet the requirements of power users for power supply reliability, in recent years, State Grid Corporation of China has accelerated the pace of construction of “strong power grids”. In particular, the main network has basically met the requirements of N-1, which provides strong support for substation equipment overhaul. For a single main transformer terminal substation, the traditional sub-equipment, sub-interval, sub-voltage level of maintenance methods can not fully meet the needs of the development of the situation, the introduction of a variety of maintenance methods is the current maintenance management needs.
