摘要
由于电力系统非线性负载的特性,使谐波电流大量注入电网,给电网带来了大量的电能质量问题。有源电力滤波器能够实现谐波检测和补偿的双重功能。针对目前检测技术存在的不足,提出了基于自适应除噪声技术的谐波检测方法。通过仿真,验证了该方法的有效性和鲁棒性。
Due to the nature of nonlinear load of the power system,harmonic current flows into the power grid greatly.It brings a lot of quality problems to the power grid. Active power filter can realize the double function of harmonic detection and compensation. Aiming at the deficiency existing in testing technology,harmonic detection method which is based on adaptive eliminating noise technology is put forward. The effectiveness and robustness of the method is verified by simulation.
