摘要
针对目前新型电力系统中测试电力电子设备在各种工况下运行情况的需要,提出利用线性自抗扰技术控制的策略,研究具有线路阻抗模拟功能的电网模拟器。在此基础上,为了对各次谐波进行分离控制,利用改进后的滤波器组进行电网电压的分离滤波,达到独立的阻抗模拟及谐波输出的效果。仿真和实验证明,所提控制策略有较好的输出效果。
In view of the need to test the operation of power electronic equipment under various working conditions in the current new power system,a control strategy using linear auto-disturbance rejection technology was proposed to study the power grid simulator with line impedance simulation function.On this basis,in order to separate and control the harmonics,the improved filter bank was used to separate and filter the grid voltage to achieve the effect of independent impedance simulation and harmonic output.Simulation and experiments show that the proposed control strategy has good output effect.
