摘要：
本文描述了一种在具有非线性非平稳电流扰动的电力系统中实现无功补偿（RPC）的方法。利用希尔伯特-黄变换（HHT）中引入的经验模态分解（EMD）将扰动从原始电流波形中分离出来，随后去除这些扰动。之后，基于著名的p-q功率理论进行功率因数校正（PFC）以消除无功功率。两种操作均在并联有源电力滤波器（APF）中实现。EMD显著简化了电流扰动的分离和去除，有助于有效识别基波电流波形，从而简化了在非线性非平稳电力系统上实现RPC的过程。
英文摘要：
This paper describes a method to implement Reactive Power Compensation (RPC) in power systems that possess nonlinear non-stationary current disturbances. The Empirical Mode Decomposition (EMD) introduced in the Hilbert-Huang Transform (HHT) is used to separate the disturbances from the original current waveform. These disturbances are subsequently removed. Following that, Power Factor Correction (PFC) based on the well-known p-q power theory is conducted to remove the reactive power. Both operations were implemented in a shunt Active Power Filter (APF). The EMD significantly simplifies the singulation and the removal of the current disturbances. This helps to effectively identify the fundamental current waveform. Hence, it simplifies the implementation of RPC on nonlinear non-stationary power systems.
