| Abstract: | A new practicable method providing real time data from SCADA to power system advanced application software through serial port under Windows NT, is illustrated in this paper. Combining MFC and WIN32 API,this method could easily transmit data under the protocol of CDT.Techniques of multithreading, data share and user defined message are employed for serial communication;Collection Class and MDI are used for data saving and data showing; By means of encapsulation, the software becomes opening and reusable. According to this method, a program has been developed to get real time data in a substation. The application shows the reliability and effectiveness of the proposed method. |
