摘要直流输电系统可靠性最优分解有助于规划、设计人员优化选择元件的可靠性, 以满足系统可靠性的要求, 是直流输电工程设备招标、规划和设计等的重要辅助决策手段。论文给出直流输电系统可靠性最优分解的非线性规划模型, 基于系统可靠性随元件可靠性参数单调递增的变化规律, 提出高压直流输电系统可靠性最优分解的二分法求解算法。该方法把给定系统可靠性指标作为约束条件, 应用二分法逐渐收敛到最优分解目标值, 进而求出满足条件的元件可靠性参数值。用一单12脉接线高压直流输电系统进行了算例分析, 在给定系统强迫能量不可用率、单极强迫停运率等指标下, 算法均能快速地收敛得到最优分解结果。

Abstract：Reliability optimal distribution (ROD) for high voltage direct current (HVDC) transmission systems can be used to choose reliability parameters of components to meet the requirement of a pre-specified system reliability performance. It is becoming an important means of decision-making for HVDC transmission project of bidding, planning and designing processes. Based on the property of the system reliability increasing with the reliability performance of components, this paper proposes a non-linear programming model for the ROD, which considers a wide range of constraints including the pre-specified system reliability. This model can be solved using the bisection method. Therefore, the optimal reliability parameters of components can be obtained. Case study of a HVDC transmission system of single 12-pulse was used to illustrate the performance of the proposed algorithm. A wide range of system reliability indices including the forced energy unavailability (FEA) and monopole forced outage times (MUOT) are the pre-specified indices. Results from the case study show that the method is feasible and effective.
