首发时间:2018-04-20
摘要:元件可靠性参数是电力系统可靠性评估的前提和基础。本文针对高压直流输电系统中存在的元件参数不确定性,基于可靠性参数与可靠性指标之间的映射关系,建立可靠性参数的校正优化模型,为原始参数的求取和校正提供了一种新的方法。最后以双12脉波接线的高压直流输电系统为例,并采用遗传算法求解,对件可靠性参数进行求解校正,计算结果验证了所提模型的正确性。

Reliability parameters Analysis for the Components of HVDC Transmission System
Abstract:Component reliability parameters are the premise and foundation of power system reliability assessment. In this paper, aiming at the uncertainties of component parameters existing in HVDC power transmission systems, based on the mapping relationship between reliability parameters and reliability indexes, a calibration optimization model for reliability parameters is established to provide a method for the determination and correction of original parameters. New method. Finally, the HVDC transmission system with double 12-pulse connection is taken as an example, and the genetic algorithm is used to solve the reliability parameters of the parts. The calculation results verify the correctness of the proposed model.
Keywords: HVDC transmission system reliability parameters Genetic Algorithm parameter solving
