The Design of Synthesis Management System of Relay Protection Based on Programming With Mixed Languages

In the paper,the OOA model and design thoughts of the synthesis management system of power system are introduced,and the functions and features of graphic system are introduced.The graphic system was developed based on Delphi and Access.Since adopting object-oriented analysis,the system is easy to be enlarged and maintained.Using the mixed-language programming of Delphi and Fortran has an advantageous complementation of the two languages.The integrated intelligent management information system has been realized by integrating the protection information on the graphic interface using the advanced visible programming technology.
