| 摘要: |
| 以系统限流指标、统一潮流控制器最大补偿度、绝缘栅双极型晶体管（IGBT）电压电流限值和直流电压限值为依据，改进了限流式统一潮流控制器（UPFC-FCL）的短路数学模型。为保证短路过程中直流电容电压不超过限值，提出了一种新的直流电容计算方法。将直流电容纳入短路限流回路，对直流限流电感的选择进行了优化，提高了装置的可靠性和经济性。建立了100 V／3 kV?A小样机实验模型，验证了限流式统一潮流控制器设计参数的合理性和有效性。 |

| Abstract: |
| The mathematical short circuit model of UPFC-FCL（Unified Power Flow Controller with Fault Current Limiting） is improved，which takes the current limit of power system，the maximum compensation degree of unified power flow controller，the voltage and current limits of IGBT and the DC voltage limit as its basis. A method for DC capacitor calculation is put forward to ensure the DC capacitor voltage lower than the limit during short circuit. The DC capacitor is added into short circuit current limiting loop and the DC current limiting inductor is optimally selected to enhance the reliability and economy of UPFC-FCL. A 100 V／3 kV?A UPFC-FCL experimental model is established，which verifies the rationality and validity of the design parameters of UPFC-FCL. |
