Abstract

As the harmonic distortion has become a main concern due to the various nonlinear loads such as uncontrolled/controlled rectifiers being used in industry. The existing multi-pulse thyristor AC/DC converter usually has to operate in a narrow voltage range so as to obtain high power factor and low harmonic injection. This paper proposes a novel multi-pulse flexible-topology thyristor AC/DC converter (MPFTTC) that keeps low total harmonic distortion (THD) and high power factor at the point of common coupling (PCC) over a wide voltage range. Detailed analyses are carried out, including the illustration of the topology-switching mechanism which drives the MPFTTC from one operating mode to the other. In order to achieve fast current control, the predictive current control strategy is presented. A promising application of the proposed MPFTTC in the wind energy conversion system (WECS) is presented, and the control strategy of the WECS is also discussed. At the end of this paper, simulation and experiment of the laboratory prototype verify the feasibility of the MPFTTC as well as the control algorithm.

基于预测电流控制的多脉冲柔性拓扑晶闸管AC/DC变换器及其在风能转换系统中的应用

由于工业中使用的非控制/可控整流器等各种非线性负载，谐波失真已成为人们关注的主要问题。现有的多脉冲晶闸管AC/DC变换器为了获得高功率因数和低谐波注入，通常必须在较窄的电压范围内工作。本文提出了一种新型的多脉冲柔性拓扑晶闸管AC/DC变换器(MPFTTC)，该变换器在宽电压范围内保持低总谐波失真(THD)和高共耦合点功率因数。详细分析了MPFTTC从一种工作模式切换到另一种工作模式的拓扑转换机制。为了实现快速的电流控制，提出了预测电流控制策略。提出了MPFTTC在风能转换系统(WECS)中的应用前景，并对WECS的控制策略进行了讨论。在本文的最后，对实验室样机进行了仿真和实验，验证了MPFTTC及其控制算法的可行性。
