摘要
电网谐波和无功功率损耗是影响电力系统电能质量的两大关键因素,因此谐波抑制技术和无功功率补偿技术对提高电网电能质量起到极其重要的作用。目前针对谐波治理主要应用的技术手段是采用并联型有源电力滤波器(APF),针对无功功率损耗主要应用的技术手段是采用静止无功发生器(SVG),文中研究并设计兼有谐波抑制功能和无功补偿功能的APF-SVG一体机系统,最后通过MATLAB Simulink仿真软件验证其可行性及有效性。
Power grid harmonic and reactive power loss are two key factors affecting the power system power quality,so the harmonic suppression and reactive power compensation technology play an important role on improving the power grid power quality. At present for the harmonic suppression,the main application is to use the shunt Active Power Filter( APF),and for reactive power loss,the main application is to use the Static Var Generator( SVG). APF-SVG system is analyzed and designed,which has both functions of the harmonic suppression and reactive power compensation. The feasibility and effectiveness of this system is verified through the simulation software MATLAB Simulink.
