Substation switching operation is the main means of grid operation mode changes and adjustments , the switching operation is to determine the switching operation is correct or not , whether the misuse determinants , therefore , properly open, according to strict audit operation ticket is to prevent the operation staff misuse of a powerful guarantee . Listed operation ticket , however it is a rather cumbersome and strong empirical work , to open, according to the correct operation ticket , the operation and maintenance of the substation must be on the grid structure composed , very familiar with the operating procedures of electrical equipment , with the solid electrical expertise and a wealth of practical experience , as well as required to always maintain a high degree of attention . The traditional manual fill operation ticket has been unable to meet the requirements of safe operation of the power grid . With the rapid increase of the degree of automation of the substation , the application of computer technology in the power system is the increasingly widespread use of computers instead of manual listed operation ticket , reduce labor intensity , improve billing efficiency , reduce billing error rate , has a very important significance . In order to solve the many defects in the manual listed operating ticket petrochemical enterprises substation developed a substation operation ticket expert system , the system as the main development tool Visual C 6.0 and Access , by a careful analysis of the application object , the establishment of the inference engine database and knowledge base , inference engine reasoning of the search , the use of expert systems technology knowledge base solution space to achieve a wide variety of operating tasks formation . Operation and maintenance personnel through the a given graphical interface , select a different operating tasks and other configuration items , will be able to automatically generate the appropriate action content . In this paper, the idea of separating knowledge base and inference engine , and make the system easier to maintain . In addition , this study design graphical operation ticket generation system operation ticket management system , operations votes billing , storage , query, statistics, printing and other functions , man-machine interface is friendly , easy to operate .
