【摘要】：当对一项变电站的设计方案进行评价时,现有的评价方法未考虑变电站全寿命周期内发生故障的次数、运行的成本、故障停电造成的经济损失等一系列因素的不确定性,并且在变电站设计方案的安全与效能方面的评价也存在不足。为解决以上问题,首先建立综合考虑上述随机变量的设计方案不确定性评价模型,同时在评价模型中兼顾安全、效能和成本(security,efficiency,and cost,SEC)因素,模型中各项指标权重采用模糊层次分析法确定;针对模型的特点,论文采用蒙特卡罗法进行模拟求解。算例表明,所提模型和方法可以有效地对新一代智能变电站综合属性进行评价,从而对新一代智能变电站的规划及建设提供指导作用。
[Abstract]:When evaluating the design scheme of a substation, the existing evaluation methods do not take into account the uncertainty of a series of factors, such as the number of faults occurring in the whole life cycle of the substation, the operating cost, the economic loss caused by the failure and power failure, etc. And the evaluation of substation design safety and efficiency is also insufficient. In order to solve the above problems, a design scheme uncertainty evaluation model considering the above random variables is established, and the security, efficiency and cost (SEC) factors are taken into account in the evaluation model. The weight of each index in the model is determined by fuzzy analytic hierarchy process, and the Monte Carlo method is used to solve the model. Numerical examples show that the proposed model and method can effectively evaluate the comprehensive attributes of the new generation intelligent substation, thus providing guidance for the planning and construction of the new generation intelligent substation.
