Embodiment Construction

[0032] Below in conjunction with accompanying drawing, the present invention is described in further detail:

[0033] refer to figure 1 , a monitoring method for a wireless module in a power distribution system, the method is realized by a power distribution terminal, a wireless module, a master station, and a host computer, wherein the power distribution terminal communicates with the host computer through a network cable, and the wireless module communicates with the master station through a wireless The wireless module communicates with the power distribution terminal through the serial port.

[0034] further reference figure 2 , the main steps of a monitoring method for a wireless module in a power distribution system are as follows:

[0035] 1) The power distribution terminal regularly sends a status data call frame message to the wireless module every 79 seconds, and the message format is:

[0036]

[0037] 2) After the wireless module receives the status data cal...

Abstract

The invention provides a monitoring method for a wireless module in a power distribution system. The main method is that the power distribution terminal regularly receives the status data from the wireless module, then analyzes and processes the data, and uploads the final data to the master station or the host computer for further monitoring. It shows that this method can not only quickly and effectively discover various abnormal situations of the wireless module, but also can make targeted treatment according to the corresponding abnormal situations, solve the abnormal problems of the wireless module in time, and avoid large-scale failures caused by wireless module failures. Large-scale power outages have greatly improved the reliability and safety of power supply, laying a solid foundation for the realization of a high degree of automation in power distribution.

Description

technical field [0001] The invention relates to the field of power system monitoring, in particular to a method for monitoring the state of a wireless module in a power distribution system. Background technique [0002] With the increase in demand for electricity and the marketization of power supply and demand, users' requirements for power supply reliability, power quality, and high-quality services continue to increase. Therefore, the rapid development of the power distribution industry in recent years is more concentrated in power distribution automation. The degree continues to increase. [0003] The degree of distribution automation depends on the protection applied in the distribution field, the intelligence of the measurement and control terminals and the number of such terminals, and the reliability of the centralized protection based on communication. Therefore, with the great investment of power grid companies in the field of power distribution, tens of thousands...
