A Distribution Transformer Open-Phase Fault Location System Based on VC++

Abstract

In order to troubleshoot the distribution transformer open-phase faults, a GSM network was set up, which could transmit open-phase information to the monitoring center automatically. From the analysis of short message in the monitoring center, system can find the person from the database who is in charge of the transformer, and sends messages to him through the serial port on the GSM. So, the maintenance personnel can troubleshoot the faults in time. A monitoring software method was designed under Visual C ++ platform. The AP1 function can be used to initialize, open and close the serial port. Based on the GSM protocol, we can write code to initialize the GSM modem, write and read SMS function in the chips. From the transformer and the person in charge information database which based on the MySQL, the system can store the information about the all working information of transformers. The use of multi-threading technology is to manage of the serial on the sending and reading short message in the same time. This design of the software has operated in several hot-points, and shows its high reliability and stability in troubleshoot open-phase faults.
