Abstract


With the deepening of the degree of attention of the electricity distribution network management , research and development of the distribution network analysis and calculation software and more attention. Distribution network reliability analysis with the power grid network structure optimization and the basis of economic operation . With the distribution network is increasingly large , increasingly complex structure , distribution network reliability modeling and calculation becomes more difficult. How to conduct a proper balance between accuracy and computational reliability calculation method to find a fast and efficient , all our problems to be solved . Therefore , to develop a visual distribution network reliability analysis software running , planning and design of the distribution network has very important significance . Access to a large number of domestic and foreign references , this paper describes the distribution network reliability analysis of the analytic method in the algorithm , simulation and visualization techniques in the application of the power system , focus on the analytical method based on the depth-first search minimal path algorithm. GDI graphics platform development tools , has developed a distribution network visualization graphics rendering platform , primitive basic editing functions and network topology automatically generated based on object-oriented technology , introduced by Microsoft VC # . Graphing module based on the extended development of a visual distribution network reliability analysis software . The software has a distribution network - substation - the feeder three tree structure in the left view ; able to easily enter the the feeder topology map right view ; powerful , reasonable structure graphical database module ; distribution network reliability index calculation module ; vivid visual reliability indicators graphics display module . IEEE RBTS-4 busbar system , for example , to verify the effectiveness and practicality of the software . Analog input graphics module modify graphics rendering , such as modifying the component failure rate or fault repair time , the impact of the various components of the degree of reliability , sensitivity analysis , identify the weak links of the reliability of power supply , suggest improvements . The software has a simple, user-friendly, easy to maintain , easy to expand and versatility features . It can provide useful reliability data for distribution network operation and planning , has a certain practical value .
