Research and Design of Distributed Remote Upgrade Technology for Voltage Monitoring Terminal

Abstract

Grid voltage monitor is a terminal to measure the voltage and the voltage distortion rate, analysis of voltage quality, is one of the essential tools for power system monitoring, assessment of power supply voltage quality. With the continuous growing number of voltage monitoring terminal and the function demand, it is a daily requirement that regularly remote upgrade voltage monitor embedded software IAP, but, remote upgrade is a high-risk operation, many manufacturers have non-unified standard to realize the upgrade process, there are still upgrading the efficiency, stability and safety of the problem to think, sometimes operation improper or communication interrupt, will cause the voltage monitor abnormal work or crash, affecting the normal operation of the whole system. This paper introduced a BP_IAP method for distributed broken-point continuouslytransferring, safety certification, to ensure reliable operation of remote upgrade, through practice test, the whole upgrade platform work efficiency and safety, reduce the transport time and save upgrading process performance.
