Abstract


With the further development of smart grid, the eleetrical power grid of China has developed into a higher automation distribution system. There will be greater risks to the safety and reliablility of distribution system as the further complexity and magnify of power system. Research of the domestic power grid reliability begins in the 80’s, most of the research stagnates at theoretical research stage and never be used to practical engineering. Therefore, there is a practical significance and application value to research the grid reliability.The main contents and the related conclusions of this dissertation are outlined as follows:1. Based on the traditional GO Method, Karnaugh Map is applied to find out the successful state.The advanced method eliminates the error of the system whose supply is not independent.To verify the accuracy of the algorithm ,the content computes the reliablility index of several main electrical wiring.2. Through the different function of the conponents(disconnect switches, breakers and tie switches),GO Method is combined with the thoughts of the domain division. The thoughts which are more suitable for calculation of the distribution networks reliability are different from the traditional domain division.3. As the GO method is based on probability theory, the distribution networks reliability can be linked with the main electrical wiring reliability.Therefore,a new reliability is proposed,that is,the reliability which is based on the superior main electrical wiring reliability.
