Abstract

In this article, a control algorithm with Adaptive Internal Model (AIM) frequency identifier has been discussed for three-phase Distribution Static Compensator (DSTATCOM). An AIM motivated method is implicated in the control scheme to extract fundamental in each phase. The reduction of reactive burden on the supply using DSTATCOM and making the supply current sinusoidal is the main theme behind this work. The fundamental extraction and PI controller gain estimation are the two things that bring variant in the proposed work. The fundamental frequency estimation, rejection of harmonics and its components are the main features of this algorithm. The convergent property of the algorithm is not much influenced by the actual disturbed signal and design parameters principally provide the robustness to the algorithm. The PI controller gains are estimated using Grasshopper Optimization Algorithm (GOA). The suggested control scheme with estimated gain values from the GOA optimization technique has controlled issues like reactive power compensation and mitigation of grid current harmonics caused due to an identified harmonic producing non-linear load that is a three-phase ac voltage controller with resistive load. This work provides implementation performance using dSPACE-1104 of the proposed control scheme for DSTATCOM.

摘要

在本文中，针对三相配电静态补偿器 (DSTATCOM) 讨论了具有自适应内部模型 (AIM) 频率标识符的控制算法。AIM 驱动的方法涉及控制方案，以提取每个阶段的基波。使用 DSTATCOM 减少电源的无功负担并使电源电流呈正弦曲线是这项工作背后的主题。基本提取和 PI 控制器增益估计是在所提出的工作中带来变化的两件事。基频估计、谐波抑制及其分量是该算法的主要特征。算法的收敛性受实际干扰信号影响不大，设计参数主要为算法提供了鲁棒性。PI 控制器增益是使用 Grasshopper 优化算法 (GOA) 估计的。建议的控制方案具有来自 GOA 优化技术的估计增益值，已经控制了诸如无功功率补偿和减轻电网电流谐波等问题，这些谐波产生的非线性负载是具有电阻负载的三相交流电压控制器。这项工作提供了使用 dSPACE-1104 为 DSTATCOM 提出的控制方案的实现性能。建议的控制方案具有来自 GOA 优化技术的估计增益值，已经控制了诸如无功功率补偿和减轻电网电流谐波等问题，这些谐波产生的非线性负载是具有电阻负载的三相交流电压控制器。这项工作提供了使用 dSPACE-1104 为 DSTATCOM 提出的控制方案的实现性能。建议的控制方案具有来自 GOA 优化技术的估计增益值，已经控制了诸如无功功率补偿和减轻电网电流谐波等问题，这些谐波产生的非线性负载是具有电阻负载的三相交流电压控制器。这项工作提供了使用 dSPACE-1104 为 DSTATCOM 提出的控制方案的实现性能。
