| In the operation of the power grid, the voltage qualification rate is a very important hard index,the level of the voltage directly affects the quality of the power of the residents, and it is related to the vital interests of every people. How to effectively and economically regulate the power grid voltage and reactive power is a very important issue in the operation of the power system. Liaoyang grid after in recent years of vigorous development, traditional, rely on human monitoring and manually adjust the voltage and by no means of reactive power has been seriously out of date, there is an urgent need to better adjust methods of voltage to voltage management.This paper introduces the design and application of AVC system in Liaoyang power grid, the principle, system architecture, sensitivity algorithm and application of AVC system in Liaoyang power grid are studied. From all kinds of AVC system to find suitable for Liaoyang power grid AVC system model.At first, this paper describes the research background, significance and research status at home and abroad, and has a clear understanding of the current research trends and existing problems. Taking the Liaoyang power grid as the template, the application scheme of the AVC master station system is designed based on the more popular centralized control theory, and the design of the main station system is completed by combining the related algorithms. The performance and requirements of the main station system are introduced.By setting the relevant rules and algorithms, the AVC system can automatically monitor the whole network voltage level, the switching capacitor and the adjustment of the transformer tap switch.Finally, has done the research to the AVC system in the actual operation of Liaoyang grid, a detailed account of the AVC system of Liaoyang, safety and stable operation of power grid, synergism of depletion of numbers, adjust the voltage, reduce network loss and other aspects of the tremendous role in promoting. |
