抽水蓄能电站静止变频起动装置SFC系统的选型分析

Selection and Analysis of SFC System of Static Frequency Conversion Starter in Pumped Storage Power Station

目前大型抽水蓄能电站多采用静止变频起动装置SFC起动作为机组的抽水调相工况主要的起动方式,是保证抽水蓄能电站正常运行的重要设备,要求具备极高的安全性、可靠性、可用率和起动成功率。在SFC系统的设计选型上,主要的型式决定了本系统的固有特性。本文对其主接线方式及冷却方式不同选项的优缺点进行定性分析,作为SFC系统设计选型时的参考,以期提高系统的稳定性及可靠性。

At present,the large-scale pumped-storage power station mostly adopts the static variable frequency starting device SFC starting as the main starting mode of the pumping phase-adjusting working condition,which is an important equipment to ensure the normal operation of the pumped-storage power station,and requires high safety and reliability.Availability and start success rate.In the design selection of the SFC system,the main type determines the inherent characteristics of the system.This paper qualitatively analyzes the advantages and disadvantages of different options of main wiring and cooling methods,as a reference for SFC system design selection,in order to improve the stability and reliability of the system..
