摘　　要：随着大型火电机组快速切回(FCB)技术的成熟,将FCB机组作为大停电后黑启动电源的设想成为可能。规划FCB机组的布点位置,应兼顾工程实际。文中首先采用图论方法推导了最优布点方案的性质,证明已知活跃顶点个数的最优布点方案具有继承性。继而提出采用递推法对FCB机组布点方案进行寻优。然后,建立了FCB机组布点方案的经济效益指标,基于递推法计算结果,依据该指标筛选出同时满足安全性和经济性要求的FCB机组最优布点方案。算例分析结果表明,递推法较常规方法计算效率高、鲁棒性强。并且,结合经济性指标,得到的结果方案可作为实际系统黑启动电源规划的决策依据。With the maturity of fast cut back（FCB）technology of large-scale thermal power units,it is now possible to use the FCB unit as the black-start power supply after a blackout.Planning the location of FCB units should take the engineering practice into account.The properties of the optimized placement scheme of FCB units are derived with the graph theory method.The successive property of the optimal placement scheme with known active point numbers is proved.Then the recursive method is presented for optimizing the placement scheme of FCB units.An economic index is then developed.Based on the calculating results of the recursive method,a placement scheme of FCB units meeting both safety and economic requirements can be obtained according to the economic index.Example analysis results show that the recursive method is more efficient and has a higher robustness than the conventional method.Meanwhile,with reference to the economic index,it can be seen that the calculation results can be used as a basis for black-start power supply planning.
