摘要
特高压电网的快速发展对1 000 kV电气主接线的可靠性提出了更高的要求,将一种以成功为导向的可靠性分析方法 -GO法引入电力系统领域,并针对操作符的相关性,提出了改进GO算法。该方法适应了主接线操作的灵活性,建立了3/2断路器和双断路器2种主接线方式的GO模型图,从不考虑元件检修的2状态模型和考虑元件检修的3状态模型两方面,对两种典型的主接线方式展开了定量的可靠性评价并给出了最终推荐方案,研究结果表明,改进GO法在主接线可靠性评价中具有优势。
Considering the rapid development of ultra-high voltage grid putting forward higher requests to reliability research of 1 000 kV main electrical connections,a new success-driven reliability assessment method called GO methodology,was introduced to the power system field. The improved GO methodology was presented through the comprehensive consideration of the operator relevance, and adapted well to the flexibility of main electrical connections operation. The GO model charts of 3/2 circuit breaker and double circuit breaker were built clearly, and the quantitative reliability evaluations of two typical main electrical connection patterns by considering the three and two state component models were carried out,and the recommended scheme was advanced. The results show that it has the advantages of reliability research on main electrical connections using improved GO methodology.
