摘要

摘要 准确的谐波估计对于有效评估电能质量、设计适当的谐波滤波器和确保电气设备的可靠运行至关重要。本文提出了一种新的混合谐波估计技术,该技术结合了递归最小二乘法(RLS)和算术优化算法(AOA),用于准确估计谐波、间谐波和次谐波。算术优化算法是一种新的元启发式方法,基于加、减、乘、除等主要算术运算符的分布行为。RLS 用于估计谐波的振幅,而相位则由 AOA 估计。利用两组埋有噪声的测试信号,详细研究了 AOA-RLS 在估计电力系统信号时的性能。事实证明,在不同信噪比(SNR)条件下,所提出的 AOA-RLS 可以有效估计相位和振幅参数,估计误差为 E-3。通过与现有竞争技术的比较,证明了 AOA-RLS 技术的有效性。AOA-RLS 的性能也在实验研究中得到了验证。

Novel hybrid arithmetic optimization algorithm-recursive least square approach for power system harmonic estimation
Abstract Accurate harmonic estimation is essential for effective power quality assessment, designing appropriate harmonic filters, and ensuring the reliable operation of electrical equipment. This article proposes a novel hybrid harmonic estimation technique combining recursive least square (RLS) and arithmetic optimization algorithm (AOA) for accurate estimation of harmonics, inter-harmonics and sub-harmonics. AOA is a new meta-heuristic method based on distribution behaviour of main arithmetic operators such as addition, subtraction, multiplication and division. RLS is used for estimation of amplitude of harmonics, whereas phase is estimated by AOA. The performance of AOA–RLS is investigated in detail for estimation of power system signals using two set of test signals buried with noise. The proposed AOA–RLS is proved to be efficient for estimating both phase and amplitude parameters under different signal to noise ratio (SNR) conditions with an estimation of error of E−3. The efficacy of AOA–RLS technique is demonstrated by comparing with competitive existing techniques. The performance of AOA–RLS also verified in experimental studies.
