具备快速切负荷(fast cut back，FCB)功能的火电机组能在外部电网发生故障时带厂用电运行，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。分析了 FCB机组对电网恢复的影响，以电网机组恢复时间最短为目标，考虑机组启动时间、启动功率、线路充电时间等约束条件，建立了FCB机组优化布点方案模型。在满足工程需要的前提下提高计算效率，引入序优化理论，确保以足够高的概率得到足够好的FCB机组的布点方案。通过经典IEEE-118节点算例和某实际系统算例验证了模型和算法的有效性。算例结果表明，合理的 FCB 机组布点方案能够减少系统恢复时间。

The thermal power generation units possessing the function of fast cut back (FCB) that they can serve for auxiliary power consumption during external faults in power grid and fast supply power after external faults cleared, so they are excellent power source for black start. The influences of FCB units on power grid restoration are analyzed, and taking the shortest restoration time of grid units as the objective and the startup time, starting power, energizing time of transmission lines as constraints, a model of optimal locating scheme for FCB units is established. To improve the computing efficiency, the ordinal optimization is led in to ensure obtaining good enough locating scheme for FCB units with as high as enough probability. The effectiveness of the proposed model and algorithm is validated by simulation results of IEEE 118-bus system and a certain actual power grid. Simulation results show that reasonable locating scheme of FCB units can speed up the restoration of power grid.
