摘要
提出一种基于无差拍算法的静止无功发生器(SVG)的控制策略。该策略不仅适用于数字控制系统,且响应速度快、可大幅度减少对电网电流谐波的引入,进行有效的无功功率补偿。在推导出SVG的主电路数学模型的基础上,研究了无功电流预测方法,将无差拍控制策略应用在SVG系统中。通过Matlab/Simulink仿真建模并搭建DSP硬件平台进行实验,验证了提出的控制策略的可行性与有效性。
Proposed a new control strategy of static var generator （SVG） based on dead-beat algorithm. This strategy was fluent application to all kinds of digital control systems, fast speed of response, significant reduction of current harmonics delivered to the grid, as well as effective compensations of reactive power. It was not only focused on the analysis of operational principle and method of current prediction based on the mathematical model of main circuits of SVG, but also on the detailed discussion of control scheme based on dead-beat algorithm applied to the system of SVG. The feasibility and effectiveness of the proposed control algorithm was verified by simulations based on Matlah/Simulink models and experiments based on DSP platform.
