发输电互联等值系统风险评估的解析模型
An Analytical Model for Risk Evaluation of Equivalent Interconnected Composite System
摘要
Abstract
For the quick and accurate calculation of bulk power system risk indices after component reliability parameters have been changed, this paper presented the analytical expressions of several risk indices with respect to components reliability parameters, on the basis of improved equivalent reliability model for interconnected bulk power systems. The algorithms and the implementation flowcharts for the risk evaluation process were also proposed. Utilizing these analytical formulas, the curves and tables were obtained through which one can not only find the different kinds of effect of component parameters on system risk indices, but also provide guide information for power system planning and benefit evaluation. In addition, the article also explained and demonstrated the importance of high level contingency to the interconnected bulk power system reliability by quantitative analysis taking the interconnected RBTS and IEEE-RTS96 test systems as examples.关键词
