Simulation and Analysis of Space Vector Hysteresis Control for Active Power Filter

随着非线性负荷越来越多接入电网,注入电力系统的谐波日益增多.大量的谐波存在会严重影响电力系统的安全稳定运行,同时也会影响对电力质量要求较高的工业企业的安全生产.电力有源滤波器是目前最受关注的电力谐波抑制技术.建立了基于FBD谐波检测方法和空间矢量滞环控制的谐波电流指令跟踪方法的MATLAB/SIMULINK仿真模型.通过仿真分析验证了有源电力滤波器在谐波治理和无功补偿方面的功能.

With the increasing number of nonlinear loads connected to the power grid,more and more harmonicsinjectes to the power system. The existence of a large number of harmonics will seriously affect the safe and stableoperation of the power system,and also affect the safety of industrial enterprises with higher power quality requirements.Active power filter is the most popular power harmonic suppression technology. In this paper,based on FBD harmonicdetection method and space vector hysteresis control harmonic current command tracking method MATLAB/SIMULINK simulation model is built. The function of active power filter in harmonic control and reactive powercompensation is verified by simulation analysis.
