New Method of Program Remote On-line Updating for Intelligent Electrical Power Equipments
LI Gang,ZHOU Yi-bo,QING Bai-yuan (Guangxi Grid Electric Power Research Institute, Nanning 530023,China) Abstract:Aiming at shortcomings of the existed methods, a new method of program remote on-line updating for intelligent electrical power equipments was proposed, with using the non-response mechanisms and historical break point continue transmission technology to avoid repeatedly sending updating data files caused by link disruption or communication failures, and the main station system resources occupied by updating program, so then the efficiency and accuracy of data remote transmission was improved. Practice had proved that the proposed method had the characteristics of high updating efficiency, updating speed and good updating flexibility, and was very applicable to the power system of many terminal equipments, large updating data files and complex environment. Key words:intelligent electrical power equipments; remote program updating; non-response mechanisms; historical break point continue transmission |
