摘要

研究目的

变流器是风力并网发电系统的核心，研究变流技术对于提高并网系统的灵活性、可靠性以及电能质量等都具有现实意义。本文采用背靠背全控电流源型变流器配置的永磁同步风力并网发电系统，结合电流空间矢量和电流多电平变流技术，探讨发电机侧最大功率跟踪（MPPT）技术和电网侧并网逆变控制技术在全控电流型变流器系统中的实现。

创新要点

结合电流型变流器的MPPT技术和多电平技术，提出既能并网发电、又能实现直流侧宽范围风速控制的全控电流型变流器风力并网发电系统。网侧采用电流多电平变流技术并应用多载波PWM调制策略，克服了传统电流源型变流器交流侧电流谐波含量高，谐波总畸变率（THD）不易满足并网要求的缺点。采用锁相环与电流解耦控制，实现了网侧可任意功率因数并网运行，提高了并网系统的灵活性。

研究方法

基于电流空间矢量方法实现发电机侧MPPT和直流母线电流控制。基于电路对偶变换构造三相电流型多电平变流器拓扑，并移植适用电压型多电平变流器的PD-PWM调制策略以消除低次电流谐波，解决了电流型多电平逆变器PWM调制策略难以实现的问题。结合锁相环与电流解耦控制，实现网侧可任意功率因数并网运行。

重要结论

发电机侧采用电流型PWM变流器，利用其内在升压特性可实现宽范围风速控制。网侧采用电流型多电平逆变器，拓扑结构与电压型多电平逆变器对偶，多电平PWM调制策略易实现；并网电流波形质量好、谐波含量低；直接电流输出控制受电网波动影响小。

Abstract

We propose a new power conversion system for a permanent magnet synchronous generator (PMSG) based grid-connected wind energy conversion system (WECS) operating with fully-controlled back-to-back current-source converters. On the generator side

two independent current-source rectifiers (CSRs) with space-vector pulse width modulation (SVPWM) are employed to regulate and stabilize DC-link currents. Between DC-link and the electrical grid

a direct-type three-phase five-level current-source inverter (CSI) is inserted as a buffer to regulate real and reactive power fed to the grid and thus adjusts the grid side power-factor. We also present a current-based maximum power point tracking (MPPT) scheme

which helps the generator extract the maximum power through closed-loop regulation of the generator speed. By applying the multilevel modulation and control strategies to the grid-side five-level CSI

a multilevel output current waveform with less distortion is produced

and the bulk requirement of the output capacitor filter to eliminate the harmonic current is reduced. All the proposed concepts are verified by simulation models built in a PSIM environment.
