摘要
在电力系统发生故障时,具备快速切负荷(fast cut back,FCB)功能的火电机组能带厂用电维持运行,并在故障消除之后迅速对外供电,是一种性能优异的黑启动电源。合理的配置FCB可带来更好的经济性。讨论了FCB功能的关键技术,分析了实现FCB技术需要的各项投资成本,结合布置FCB机组带来的用户停电损失的减少,建立了经济指标函数,计算经济性最优的FCB机组配置方案,并通过IEEE-118节点算例和广东省实际算例进行分析,为研究FCB机组在实际电网中的合理配置提供了参考。
Fast Cut Back (FCB) thermal power units can be used as blackstart units to boot up power system restoration. The key technology for realizing FCB function is discussed in the paper. Besides, the related costs, in terms of the cost of achieving FCB function and the cost of using FCB function, are also estimated. With consideration of the reduced outage cost brought by FCB units, an economic indicator function is huih to calculate the economically-optimum allocation of FCB units, and an economic analysis is carried out through case study of an IEEE- 118 power system and a power grid in Guangdong province. The result can provide a reference for reasonable allocation of FCB units in the practical power grids.
