Xie Yin-zhe · Zhejiang Electric Power · 2012
The main functions and features of risk analysis and decision support system of Hangzhou distribution networks are introduced.By introduction of risk theory and on the basis of CIME and state enumerating algorithm,risk index assessment and comprehensive star-rated assessment scheme is established for quantitative assessment on overhauling.In combination with consequence analysis of contingency in power grid,the paper describes operational risks of distribution networks.The practical operating experience shows that the system can effectively guide the operation of power grid.
