无功率发生器SVG在电力系统中的应用

随着工业的不断发展,电能的需求量将越来越大,电能的利用率直接影响电网的供电效率。为了提高电力系统中电能的输送质量,降低无功功率,而无功率发生器SVG是目前无功功率补偿领域最佳方案,相比以往传统的调相机、电容器电抗器补偿及以晶体管控制电抗器TCR为代表的SVC补偿装置等更具有优越的性能。文章主要介绍无功率发生器SVG的基本工作原理及控制方法,并从性能上与传统电容补偿器及SVC系统作以比较,介绍SVG系统优化节能运行及日常维护方法。

Application of Non-power Generator SVG in Power System

With the continuous development of industry, the demand for electric energy will become larger and larger. The utilization rate of electric energy directly affects the power supply effciency of the power grid. In order to improve the transmission quality of electric energy in the power system, it is necessary to improve the power factor and reduce the reactive power, and SVG is the best scheme in the field of reactive power compensation at present, compared with the traditional condenser, capacitor reactor compensation and SVC compensation device mainly represented by TCR, the basic working principle and control method of SVG, compares the performance with traditional capacitor compensator and SVC system, and introduces the routine maintenance method of SVG are mainly introduced in this paper.
