摘要

对高压直流（HVDC）输电系统进行可靠性灵敏度分析可以辨识系统的薄弱环节，对改善系统可靠性具有重要意义。文中提出一种分析HVDC输电系统可靠性灵敏度的方法:用最小二乘法拟合HVDC输电系统可靠性指标随元件可靠性参数变化的曲线，并根据拟合曲线即可得到元件对系统可靠性的灵敏度。当HVDC元件的可靠性参数发生变化后，为了快速估算出该参数对应的灵敏度，提出灵敏度曲线的概念，并推导了其解析表达式。对一单12脉接线HVDC输电系统进行灵敏度分析，证实了该方法的可行性和有效性。

Abstract

Weak parts of a HVDC transmission system can be recognized using sensitivity analysis， which has been an important technique for system reliability assessment and enhancement. A new sensitivity analysis method for HVDC system is proposed in this paper. The least square method is used to model the relationship of HVDC reliability indices varying with the reliability parameters of components. It can be used to obtain the sensitivity formula of system reliability indices with respect to parameters of system components. The concept of sensitivity curve and its analytical expression are also proposed. Based on the sensitivity curve， sensitivity indices can be estimated rapidly when the reliability parameters of components are changed. A single 12-pulse HVDC transmission system is used to illustrate the proposed method. Case studies indicate that the method is feasible and effective.
