基于DSP的TCR+FC型静止无功补偿系统控制部分的设计

摘要

The dissertation mainly include the followed parts:the improvement of the electric net's capability by the reactive power compensation,the control method of reactive power compensation device and the hardware and software design of the device.A high performance digital signal processor TMS320F28335 is as the controller's CPU.DSP has many merits such as high operating speed and high real-time.In this paper,the technology of self-adapt modulate sampling time and FFT (Fast Fourier Transform)algorithm are both adopted,which can realize auto-tracking the change of frequency and compensate dynamically reactive power.%主要研究了无功补偿对电网性能的改善,无功补偿装置的控制方式及控制器的软硬件设计.在硬件上,采用TI公司的32位浮点DSC TMS320F28335为控制器的CPU,根据测量和控制的要求设计相应的硬件电路.在软件设计上能准确跟踪系统无功变化,达到对系统无功功率动态实时补偿.
