摘要
随着功率开关器件的进步,大量的电力电子变流装置在国民经济各领域获得了广泛应用,但是这些变流装置大部分都需要整流环节。传统的不控整流或相控整流存在网侧功率因数低、电流畸变严重等缺点。PWM整流器可实现正弦的网侧电流、单位或可调的功率因数、能量的双向流动,是一种真正意义上的“绿色环保”电力电子装置。PWM整流器可分为电压型PWM整流器(Voltage-Source Rectifier,VSR)和电流型PWM整流器(Current-Source Rectifier,CSR)。CSR具有直接控制输出电流、动态响应快、限流能力强等特点,在一些中、大功率应用场合,较之VSR,在经济和技术上更具优势。
     本文针对电网电压平衡、不平衡情况、多模块直接并联几个方面,对三相CSR及其控制策略展开了深入研究,论文的主要工作和取得的创新性成果如下:
     1、在电网电压平衡情况下,提出了三相CSR的直流电流非线性解耦控制策略和交流电流非线性解耦控制策略,实现了有功功率和无功功率的独立、解耦控制,获得了线性的动态响应。直流电流非线性解耦控制策略是直流电流控制和网侧无功电流控制并行的控制策略,具有较快的直流电流响应速度;交流电流非线性解耦控制策略是直流电流(或电压)控制和网侧电流控制级联的控制策略,具有结构简单,便于独立设计直流和交流控制器的特点。
     2、考虑了电网电压不平衡和滤波器参数三相不对称的情况,提出了基于瞬时有功功率调节的三相CSR的不平衡补偿策略,消除了直流电流脉动分量,实现了网侧可控的功率因数和正弦的交流电流;提出了基于滑模控制的交流电流控制策略,简化了控制器结构,实现了对网侧电流的无差跟踪。
     3、建立了多模块直接并联CSR的环流模型;对任一并联模块,提出了总直流电流控制器外加2个均流控制器的直流侧控制器结构,保证了流过各模块上、下桥臂的电流均相等,并且各模块仅共享总直流电流控制器输出信号,最大可能地保证了各模块控制的独立性。
     4、建立了三相CSR实验系统,进行了初步的实验研究。
With the development of power electronics devices, a lot of power electronics equipments have been widely used in different industry. However, most of these equipments need rectifiers, the traditional phase control rectifiers and diode rectifiers have disadvantages such as low line power factor, heavy line current distortion. The PWM rectifier is a“green”power electronics equipment since it offers sinusoidal input currents, unity or adjustable power factor, reversal of power flow. The PWM rectifiers can be classified into voltage-source rectifiers (VSR) and current-source rectifiers (CSR). CSR is more attractive then VSR in some high or medium power applications due to their advantages such as controlling the output current directly, fast dynamic response, high capacity of limiting the short-circuit current.
     This dissertation studies the CSR and its control strategies under balanced supply voltge, unbalanced operation conditions and parallel operation of multi-modulars, the main contributions include the following aspects.
     1. Assuming that the supply voltage is balanced, for dealing with the nonlinearity and the state variable coupling of the CSR mathematical model, the dc current nonlinear control and ac current nonlinear control are proposed, which achieve decoupling, independent control of direct and quadrature line current components and linear dynamic response. For the dc current nonlinear control scheme, the dc current controller is parallel to the quadrature line current controller, and a faster dc current transient response is obtained. For the ac current nonlinear control scheme, the dc current controller is cascade to the direct line current controller, which is convenient to design the dc controller and the ac controller independently.
     2. Under unbalanced operation conditions, a new control method based instantenous active power regulation is proposed, which can not only eliminate the input output harmonics of the CSR but also obtain controllable power factor and sinusoidal line currents. In addition, a ac current controller based sliding-mode control in stationary frames is designed, which simplifis the controller structure and tracking the line current accurately.
     3. A novel circulating current model of multi-modular CSR is established. For each parallel three phase CSR modular, a new controller structure of the CSR dc side is proposed, which includes a total dc current controller and two current equalization controllers. The proposed structure assures that currents flowing through the upper and lower bridges of each modular are equal and control of the each CSR modular is indenpent since only one signal is shared among modulars。
     4. A experiment system of three phase CSR is set up and basic experiments are carried on.
