| Abstract: | The power supply reliability evaluation rules of the network is extended on the base of the traditional method. The influence of the common mode fault in the double line on the same pole, bus fault and key substation fault on the power supply reliability are emphatically researched. Following the extended evaluation rules, the calcu- lation model of quantitative analysis is established, its solving method is studied. In the end, the research result is applied to evaluate the security and reliability of the 220-500 kV network planning scheme in a certain city in east China in 2010, the weak parts of the scheme are analyzed which provedes basis for the further revision and amendment. |
