摘要：

The availability of UPFC(Unified Power Flow Controller) depends on the reliability of its components and their routine test strategies. According to the sudden failure ratio of the component, a calculative method of the transition rate of the component with abnormal state is proposed, and the state-space model of UPFC with abnormal state and routine test is built. A sensitivity model of UPFC reliability to failure ratio of the component is built to confirm the vulnerable component, moreover the influence of the routine test parameters on the UPFC's reliability is quantified. According to the analytical results of sensitivity model, the vulnerable component of UPFC is confirmed, the reliability of UPFC with abnormal state and the routine test is quantified, and the influences of the ratio of sudden failure and the ratio from the abnormal state to failure state on the UPFC's reliability are analyzed. The accuracy of the sensitivity analysis method of UPFC reliability with routine test is verified by comparing with the perturbation method. © 2022, Electric Power Automation Equipment Press.
