摘要

本文提出了一种简单的基于级联双电平逆变器的多电平逆变器的STATCOM方案。所提出的拓扑结构具有两个基于VSI的双电平逆变器，通过三相变压器和滤波器元件的开放式绕组级联连接。变流器直流电压被调节到不同的电平，以获得四电平的工作。所提出的STATCOM多电平逆变器在MATLAB/SIMULINK环境下运行，并在平衡和不平衡条件下对结果进行了验证。进一步研究了该拓扑结构的稳定性行为。建立了动力学模型，推导了不同工况下的传递函数。分析了系统在各种工况下的运行行为。

A New Cascaded 2-Level Inverter basedSTATCOM for High Power Applications

This paper presents a simple STATCOM scheme using a cascaded two-level inverter-based multilevel inverter. The proposed topologies have two VSI based two-level inverters are connected in cascade through open-end windings of a three-phase transformer and filter elements. Converter fed dc-link voltages is regulates at different levels to obtain four-level operation. The proposed STATCOM multilevel inverter has operates under MATLAB/SIMULINK environment and the results are verified in balanced and unbalanced conditions. Further, stability behavior of the topology is investigated. The dynamic model is developed and transfer functions are derives under different conditions. The system behaviors are analyzing under various operating conditions.
