Abstract
With the rapid development of the power industry and the increasingly complex power load, the power quality problem in the power system is increasingly prominent, which has become the key factor affecting the safe and stable operation of the power grid, the service life of power equipment and the quality of users. As an important means to ensure the healthy operation of the power system, power quality monitoring and governance have attracted wide attention in recent years. This paper aims to comprehensively explore the power quality monitoring technology, evaluation method and governance strategy in the power system, in order to provide scientific basis and technical support for improving the power quality and optimizing the allocation of power resources. This paper summarizes the basic concepts and classification of power quality, including voltage deviation, frequency deviation, harmonic, voltage fluctuation and flash, three-phase imbalance and other common power quality problems. These problems will not only lead to the decline of equipment performance and life shortening, but also may cause system failure, causing adverse effects on power production and user electricity consumption. This paper analyzes the current situation and development trend of power quality monitoring technology. Modern power quality monitoring technology integrates sensor technology, signal processing technology, communication technology and big data analysis and other advanced technologies, to realize the real-time and accurate monitoring of power quality indicators. At the same time, with the promotion of smart grid construction, a power quality monitoring system based on the Internet of Things and cloud computing is gradually being constructed, providing strong support for the realization of comprehensive perception, intelligent analysis and accurate governance of power quality. In terms of power quality assessment, this paper introduces a variety of evaluation methods and index systems, including evaluation methods based on national standards and industry standards, personalized evaluation methods based on user needs, and comprehensive evaluation methods based on big data analysis. These methods provide scientific basis for accurately evaluating the power quality level and diagnose the root of the problem. This paper focuses on the management strategy of power quality. According to different types of power quality problems, corresponding treatment measures and technical means are put forward, such as installing reactive power compensation device to improve voltage deviation, using active filter to suppress harmonic pollution, optimizing power grid structure to reduce voltage fluctuation and flicker, etc. At the same time, it emphasizes the importance of cross-field cooperation and comprehensive governance, and points out that the power quality level of the power system can be comprehensively improved by strengthening power grid planning, optimizing dispatching and operation, and promoting efficient and energy-saving equipment.
