提出了一种基于风险评估的老化高压直流输电元件更换策略。它包括估计由于老化故障的单个HVDC组件的不可用性，HVDC系统的容量状态概率的计算，包含HVDC链路的电力系统的量化风险评估和不同更换策略的效益/成本分析。所提出的方法也可以应用到其他系统组件。以不列颠哥伦比亚省输电公司高压直流输电线路老化海底电缆的更换策略为例进行了分析，并对实际应用进行了说明。在实例中详细说明了分析的过程。
This paper presents a risk evaluation based approach to the replacement strategy of aged HVDC components. It includes estimation of unavailability of individual HVDC components due to aging failures, calculation of capacity state probabilities of the HVDC system, quantified risk evaluation of the power system containing the HVDC link and benefit/cost analysis for different replacement strategies. The presented approach can be also applied to other system components. The replacement strategy for an aged submarine cable of the HVDC link in a power supply system at British Columbia Transmission Corporation has been analyzed as an example to demonstrate the actual application. The procedure of the analysis has been explained in detail in the example.
