本文分析了断路器重合闸失败情况下最优重合闸与模糊逻辑控制制动电阻的配合对多机电力系统暂态稳定性的影响。将最优重合闸与模糊控制制动电阻协调运行与常规自动重合闸与模糊控制制动电阻协调运行的暂态稳定性能进行了比较。通过九总线电力系统模型和十机系统的仿真验证了所提出方法的有效性。对电力系统不同点的平衡和不平衡故障的仿真结果表明，最优重合闸和模糊控制制动电阻的协调运行能够在重合闸失败的情况下很好地稳定系统。而且，最优重合闸与模糊控制制动电阻协调运行的暂态稳定性能优于常规自动重合闸与模糊控制制动电阻协调运行的暂态稳定性能。
This paper analyzes the effect of the coordination of optimal reclosing and fuzzy logic-controlled braking resistor on the transient stability of a multimachine power system in case of an unsuccessful reclosing of circuit breakers. The transient stability performance of the coordinated operation of optimal reclosing and fuzzy controlled braking resistor is compared to that of the coordinated operation of conventional auto-reclosing and fuzzy controlled braking resistor. The effectiveness of the proposed method is confirmed by simulations in case of a nine-bus power system model as well as a ten-machine system. Simulation results of both balanced and unbalanced faults at different points in the power systems show that the coordinated operation of optimal reclosing and fuzzy controlled braking resistor is able to stabilize the systems well in case of an unsuccessful reclosing. Moreover, the transient stability performance of the coordinated operation of optimal reclosing and fuzzy controlled braking resistor is better than that of the coordinated operation of conventional auto-reclosing and fuzzy controlled braking resistor
