[Abstract]:In modern society, with the continuous development of economy and the continuous progress of technology, electric energy as a kind of economy, easy to convert, safe and practical energy, has become the most widely used energy. The development and application of electric energy has become an important symbol of evaluating the development level of each country. In recent years, our dependence on electric energy is still increasing, but the relative development of power industry has encountered more and more problems in recent years, among which power quality is an important symbol to measure the operation of power grid. More and more attention has been paid to the related problems. In order to improve the quality of power supply, the energy efficiency monitoring system can not be replaced as the data acquisition terminal. In recent years, the voice of establishing smart grid is more and more high. This paper deeply studies the research status and working principle of the power monitoring device, and completes the software and hardware design of the intelligent power energy efficiency monitoring system. It can monitor the phase parameters of the power grid in real time and lay the foundation for the future smart grid. Based on the study of a large number of literatures and the design requirements of intelligent power energy efficiency monitoring system, the functions and performance of intelligent power energy efficiency monitoring system are analyzed in this paper. This paper presents a scheme of building power monitoring module based on PIC24FJ128GA310 chip and information centralization module based on STM32F103ZET6 chip respectively. The scheme responds to the command of host computer by communicating with host computer through information centralization module. The power monitoring module monitors the parameters of voltage, current, power, frequency, power factor and so on in real time, and then transmits the data to the information centralization module by communication protocol in response to the command of the information centralization module. The intelligent power energy efficiency monitoring system has the characteristics of low cost, reliable performance and small volume, which can measure several monitoring points in real time at the same time. The intelligent power energy efficiency monitoring system is composed of centralized information module and multiple power monitoring modules. It can monitor the real-time running status of multiple monitoring points of a single user, so that the user can fully understand the state of power and supply of their own equipment and monitoring points. The intelligent power energy efficiency monitoring system based on this scheme has good accuracy, real-time and reliability, and has been tested and put into operation. The test and operation results show that the device has a good performance-price ratio. Can meet the site engineering technical requirements.
