摘要
电力电子技术的迅速发展,使得电力网中的非线性负载元件的数量越来越多,而这些非线性负载又是电网谐波的主要来源,谐波会给电网带来严重的污染,使谐波的含量降低到规定的范围之内是现代电力行业迫切需要解决的一个问题。在治理谐波的领域中,有源电力滤波器已经走在了时代的最前列。该文以数字处理器芯片TMS320F2812为核心设计的有源电力滤波器控制系统,补偿电流的计算是通过瞬时无功功率理论的计算方法来实现的。首先在MATLAB环境中搭建有源电力滤波器的仿真模型,得出可行性的分析结果。接着设计了基于TMS320F2812的并联型有源电力滤波器控制系统的硬件和软件结构,通过在样机上试用的结果表明,在技术上是完全可行的。
The amount of nonlinear load element is more and more in the power network with rapid development of power electronics, and the nonlinear load is the main source of harmonic to power grid, the harmonics generated by nonlinear load element has brought the serious pollution to power grid. To keep harmonic content in the range of provisions is urgent problem in modern electric power industry. On the field of suppresing harmonic, active power filters have been walking in the forefront of the times. This thesis takes digital processor chip TMS320F2812 as the core to design control system of active power fil- ter. The calculation of compensation current is accomplished through the theory of instantaneous reactive power method. First, to build active power filter simulation model in the MATLAB environment in order to get analysis results about feasibility of control system. Then design hardware and software structures of active power filter control system based on TMS320F2812. The results in the prototype show that the technolgy of active power filter is feasible.
