摘要
变电站交直流一体化电源系统方案实现了多套站用电源系统蓄电池组的共用,多套电源系统的集中监控、集中管理,一套设备多种电源输出。因交直流一体化电源系统方案具有集成度高、管理简便等诸多优点,该方案已在国家电网公司全国各电压等级变电站得到广泛应用,南方电网公司也在逐步扩大应用范围。但多年以来交直流一体化电源系统所存在的标准化低、不同品牌器件兼容性差、维护成本高等问题一直未从根本上得到解决。交直流一体化电源系统一方面维护效率低、维护成本高,同时严重影响到了变电站的可靠运行。文章针交直流一体化电源系统所存在标准化程度低的问题,提出全模块化电源系统方案。
The scheme of integrated AC/DC power supply system for substation realizes the sharing of batteries in several sets of station power supply system,the centralized monitoring and centralized management of multiple sets of power supply systems,and the output of multiple power sources for one set of equipment.Because the integrated AC/DC power system has many advantages such as high integration and simple management,this scheme has been widely used in various voltage grade substations of the State Grid Corporation,and the Southern Power Grid Corporation is gradually expanding the scope of application.But for many years,the prob lems of low standardization,poor compatibility of different brand components and high maintenance cost have not been fundamentally solved in the integrated AC/DC power supply system.On the one hand,the integrated AC/DC power supply system has low mainte nance efficiency and high maintenance cost;on the other hand,it seriously affects the reliable operation of the substation.In this pa per,the problem of low standardization exists in the integrated AC/DC power supply system,and the scheme of fully modular power supply system is put forward.
