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.
