中文摘要
      应用在双馈风力发电系统中的功率变换器必须具有功率双向流动的能力, 交直交循环变流器和交交矩阵变换器都可满足功率的双向流动要求. 而矩阵变换器能同时提供正弦的输入电流和输出电压, 输入电流可调节为超前、滞后或同相于输入电压, 输出电压可实现幅值、频率和网侧功率因数的独立控制. 利用矩阵变换器, 通过控制无刷双馈电机控制绕组的电压幅值、频率, 为风力发电系统提供励磁. 压频比控制器采用模型参考模糊自适应控制策略, 对电机的转速和功率因数进行控制. 采用DSP,CPLD构建了基于四步换流方案的矩阵变换器实验励磁系统, 仿真和实验结果验证了系统设计的正确性、可行性和稳定性, 为矩阵式变换器的实际应用提供了实验基础.
英文摘要
      Power converter used in doubly-fed wind generator system must possess the capability of bi-directional power flow. Both AC/DC/AC converter and AC/AC Matrix converter(MC) possess this capability, but MC can provide sinusoidal input current and output voltage simultaneously, and the phase of input current can be adjusted to lead, to lag or to coincide with the phase of the input voltage. The magnitude and frequency of the output voltage and the input power factor can be independently adjusted in MC. MC is used to control the voltage magnitude and frequency in the control winding of brushless doubly-fed machine(BDFM), in order to supply excitation for wind generator system. The model reference fuzzy adaptive control strategy is used to control the ratio of voltage versus frequency to regulate the machine rotor speed and power factor. Digital signal processor(DSP) and complex programable logic device(CPLD) are used to construct a MC experiment excitation system based on four-step commutation strategy. The validity, feasibility and stability of the system design are proved by simulation and experimental research. MC is advantageous to practical applications in the future.
