摘要

本文提出了一种智能逆变器控制方法，用于降低三相逆变器供电电网直流母线电压的噪声、干扰和突跳。采用Matlab/Simulink 2020对系统进行建模。导致直流电源波动的原因有很多，比如连接松动、腐蚀或不稳定。本文提出了一种采用反馈FB和前馈FF两自由度控制器解决三相电压源逆变器直流电源波动的方法。结果表明，FB仅能解决直流电压的扰动和突跳问题。采用FB和FF两种控制器解决了这一问题，在直流电源±15%波动的不同负载条件下，超调量、上升时间、峰值时间和稳定时间参数等性能都得到了改善

Reducing the Fluctuations Effect of the DC supply on the Three Phase Inverter using Intelligent Inverter Control

In this paper, an Intelligent inverter control is used to reduce the noise, disturbances, and sudden jumps in DC bus voltage of the grid supplies a three-phase inverter. The system is modelled using Matlab/Simulink 2020. Many reasons cause fluctuations in a DC supply such as loose, corroded connections, or unregulated supply. The paper proposes a solution for fluctuations in DC supply of three phase voltage source inverter using two degree of freedom controllers Feeback FB and Feedforward FF. The results show that FB only can't solve the disturbances and sudden jumps of the DC voltage. Using both controllers FB and FF solve this problem and the performance such as overshoot, rise time, peak time, and settling time parameters are improved under different load conditions for ±15% fluctuation in DC supply

期刊介绍： WSEAS Transactions on Power Systems publishes original research papers relating to electric power and energy. We aim to bring important work to a wide international audience and therefore only publish papers of exceptional scientific value that advance our understanding of these particular areas. The research presented must transcend the limits of case studies, while both experimental and theoretical studies are accepted. It is a multi-disciplinary journal and therefore its content mirrors the diverse interests and approaches of scholars involved with generation, transmission & distribution planning, alternative energy systems, power market, switching and related areas. We also welcome scholarly contributions from officials with government agencies, international agencies, and non-governmental organizations.
