摘　　要：根据规范规定,当抽水蓄能电站机组台数少于6台时,宜选用1套变频起动装置(SFC),并以背靠背同步起动(BTB)作为备用起动方式。近年来,不少建设单位提出在机组台数为4台的抽水蓄能电站中配置2套SFC的方案。为充分论证此方案的合理性,笔者从系统调度、电站运行、设备布置和全寿命周期费用角度将此方案与规范推荐的方案进行对比研究。结果表明,此方案具有机组起动成功率更高、对电网需求响应速度更快并能简化电站的运行管理等多方面优点。随着SFC国产化的深入,全寿命周期费用会进一步降低,该方案的优势会更明显,可作为合理的机组起动方式备选方案。According to the specification when the number of pumped storage power station units is less than six a set of static frequency converter SFC should be selected and the back-to-back synchronous starting BTB should be used as the standby starting mode.In recent years many construction enterprises have proposed the scheme of configuring two sets of SFC in pumped storage power stations with four units.In order to fully demonstrate the rationality of this scheme the authors compare this scheme with the recommended scheme from the perspective of system scheduling power station operation equipment layout and life cycle cost.The results show that this scheme has many advantages such as higher success rate of unit starting faster response to power grid demand and simplified operation and management of power station.With the deepening of SFC localization the life cycle cost will be further reduced and the advantages of this scheme will be more obvious which can be used as a reasonable alternative for unit starting mode.
