Abstract

This paper presents the research platform for real time digital simulation applications which replaces the requirement of full scale or partial scale validation of physical systems. To illustrate this, a three phase AC-DC-AC converter topology has been used with diode rectifier, dc link and ideal two level inverter with inductive load. Because of natural decoupling between rectifier and inverter, it is easy to solve the state equation with reduced order system using decoupled method. This method utilizes analytical to formulate the state equations and to rectify the zero crossing errors taylor’s method of interpolation has been implemented which leads to variable step time during that instant otherwise fixed step size of 100 μS is used. The proposed algorithm has been validated in simulation and real time controller domain. Performance of the converter is evaluated based on accuracy, zero crossing and tabulated

基于解耦分析方法的电力电子变换器实时数字仿真建模研究平台的开发

本文提出了一种实时数字仿真应用的研究平台，以取代对物理系统进行全尺寸或部分尺寸验证的要求。为了说明这一点，我们采用了一种三相AC-DC-AC变换器拓扑结构，其中包含二极管整流器、直流链路和带感性负载的理想二电平逆变器。由于整流器和逆变器之间具有自然解耦性，因此采用解耦方法求解降阶系统的状态方程非常容易。该方法利用解析法建立了状态方程，并对过零误差进行了修正，采用泰勒插值法，使得该时刻的步长变，否则采用固定的100 μS步长。该算法已在仿真和实时控制器领域得到验证。对变换器的性能进行了精度、过零和表化评价
