Research On Power Quality Monitoring Method And Load Control System Research

Degree of the application and development of electricity in a sense, things of the country's economic development level and comprehensive strength, as a kind of clean and renewable energy, is widely used by humans. With the development of the existing economy, energy is not only meet the demand of people's life and industrial production, but on the premise of meet the basic demand for more improve the quality of electric energy. This trend is an inevitable result of social development, the global informationization is the embodiment of the rich people's living standard, the industrialized production is developed. Quickly raise level of science and technology in modern society, social and cultural civilization rapid development, the improvement of power quality is also inevitable trend. Not only can improve the efficiency of electricity and improve the use of electricity environment, also can improve the efficiency of the national economy development and the sustainable development of the industrialization. Present development trends, in order to improve the quality of electricity must be real-time monitoring and detection of electric energy, at the same time, a certain degree of control so as to achieve the purpose of improving power quality. The level of power quality and power system operation condition and the management level has a close relationship.Therefore, this paper according to the situation existing grid development, analysis of the needs of future prospects for the development of smart distribution grid is proposed to solve the problem means that distributed intelligent switching power quality detection and power load control functions. According to the national grid power quality requirements, and for the energy shortage problem in the case of some power quality testing and control related power load, the paper describes some of the conventional control method to detect power quality and power load, power quality interruptible load control method of power load control method when an exception occurs, and when emergency power shortage.System design. Article first based on the results of theoretical research and experiment, first determine the instrument of power quality monitoring device for the relevant indicators of power quality monitoring. Analyzed the traditional study of the practice of how to control the load, and decided to adopt the modular design idea for hardware design. Then implement a software programming and development. In the process of software development, mainly is the use of the modular programming and the design concept of subroutine calls. And design corresponding hardware module, software system consists of data acquisition module, data processing module, etc. Completed the design of hardware modules and software modules, requires a combination of functional effectiveness of the whole system debugging.
