Study on the conversion of multiple communication protocols between power quality improvement auxiliary devices

In order to overcome the difficulties encountered in the current debugging of different equipment, to reduce the workload of different equipment debugging, and to improve the standardization of the interface and power quality, this paper proposes a construction method of multiple communication protocol conversion system between auxiliary devices to improve power quality. The construction method is based on the principle of embedded intelligent protocol converter, which can be compatible with a variety of common communication protocols on the market. Based on this, the construction method takes the power line carrier communication as the carrier, and takes the COAP-lot protocol as the conversion target protocol, which can provide two major functions for the power quality auxiliary equipment, namely, data exchange and plug and play. The research results show that the construction method can greatly reduce the debugging workload of different equipment, and break the limitations of traditional power quality improvement equipment.
