Power supply system key information acquisition system and communication method based on Beidou satellite transmission and communication method thereof

Abstract

The invention relates to a power supply system key information acquisition system and communication method based on Beidou satellite transmission, belonging to the field of remote monitoring of a power supply system. The system consists of a main station side system and a factory station side system, wherein the main station side system comprises a main station side data server and a Beidou satellite command airplane, and the Beidou satellite command airplane is connected with the main station side data server; the factory station side system consists of a three-phase acquisition circuit, a multi-path analogue-to-digital conversion integrated circuit, an intelligent electric energy meter, a Beidou satellite subscriber machine, a processor, a display and a data storage device, and the three-phase acquisition circuit is connected with the multi-path analogue-to-digital conversion integrated circuit; the multi-path analogue-to-digital conversion integrated circuit is connected with the processor; and the processor is respectively connected with the intelligent electric energy meter, the Beidou satellite subscriber machine, the data storage device and the display. The system has the advantages of reinforcing the accuracy, the timeliness and the safety of key data transmission, monitoring a distributive mini-type hydropower station in real time, improving the running management level of the mini-type hydropower station and optimizing the power flow distribution of a power grid so as to reduce the loss of the power grid and exert the effects of energy saving and emission reduction.

Description

【Technical field】 [0001] The invention relates to a power system key information collection system and a communication method based on Beidou satellite transmission, belonging to the field of remote monitoring of power systems. 【Background technique】 [0002] At present, there are hundreds of small hydropower stations and comprehensively utilized small power plants in operation. Most of these small power generation enterprises are not very sound in automation equipment and communication network, and most of them do not have the conditions to communicate with the power dispatching center. Therefore, these Most of the real-time information of small power plants cannot be uploaded, and there is a lack of technical means for real-time monitoring. Therefore, most of the real-time information of these small power plants cannot be uploaded, lacking technical means for real-time monitoring. GPS does not have the function of two-way SMS communication, and the use of GPS system to tr...
