Power data acquisition and remote transmission system based on GPRS communication module

Abstract

The present invention relates to a power data acquisition and remote transmission system based on a GPRS communication module and belongs to the technical field of power system data acquisition and transmission. The power data acquisition and remote transmission system comprises a control system, an electric power acquisition concentrator, and a main station server. The control system is disposed inside a power plant. One end of the electric power acquisition concentrator is in communication connection with the control system via a data interface. The other end of the electric power acquisition concentrator is in connection with the main station server via a GPRS communication interface. The electric power acquisition concentrator comprises a single-chip microcomputer, an AC sampler, a serial communication module, an Ethernet communication module, the GPRS communication module, a transmission interface, and a memory, wherein the single-chip microcomputer is connected with the AC sampler, the serial communication module, the Ethernet communication module, the GPRS communication module, the transmission interface, and the memory. Compared with a prior art, the power data acquisition and remote transmission system efficiently acquires the power generation state and the heat supply state of a power generating enterprise in real time and increases the operation stability and security of power enterprises.

Description

technical field [0001] The invention belongs to the technical field of power system data collection and data transmission, in particular to a power data collection and remote transmission system based on a GPRS communication module. Background technique [0002] With the rapid development and improvement of the national economy, the installed capacity of the power industry and the power grid have developed rapidly, and more and more new power plants have been built, and some enterprise-owned power plants that use waste heat and pressure to generate electricity have also been put into operation one after another. In terms of power supply control, most power generation companies are still limited to the display level of surface data, lacking scientific theoretical model support. There are many types of units in each power generation enterprise, and under different working conditions, the steam extraction, heat supply and unit output are mutually restrictive; at this stage, the...

AI Technical Summary

Problems solved by technology

Each power generation company has a large number of unit models, and under different working conditions, the steam extraction, heat supply and unit output are mutually restrictive; at this stage, there is a single means of controlling the production status of power generation companies, and most of them are manually reported. It is difficult to guarantee the real-time, high efficiency, and accuracy of data, and it is impossible to make timely adjustments in response to some emergencies of power generation companies, which affects the quality of power supply
