Research On Visible Computer Setting Calculation And Database Management System In Rural Power Networks

On the basis of investigating present development of computer software about protective Relay Setting Calculation, this paper summarized the shortcomings: the generalization of software is unsatisfactory, the user can't maintain the system easily, and the interface is unfriendly. In order to improve the universality and practicability of software, by using Visual C++ as the development tool, the paper presents a setting calculation software in rural networks, which is developed by combining computer graphical theory and OOP. The software includes three modules, i.e. the graphics module, the database module and the graphical setting computation module. The three modules integrate into a whole system. The whole system is designed under the OOP ideology. The graphical module can draw the key diagram of power system. All the data of distribution systems can be input, browse and edit through the graphical interface. Though the setting computation module, the user can combine his experience to get the result quickly and directly. Through practical running in the power system of our country, the results indicate that the software is efficient and accurate.Li Yonghong (Electric Engineering)Directed by prof. Liu Guanqi...
