摘要

摘要: 由于电力电子元件仿真在仿真步长及计算精度等方面的高要求,普通的平台很难进行变流器的实时仿真。针对这一问题,本文以双馈发电机(doubly\|fed induction generator, DFIG)励磁用双脉宽调制(pulse width modulation,PWM)变流器为研究对象,在现场可编程门阵列(field\|programmable gate array,FPGA)上进行了变流器模型及其控制系统的硬件实时模拟。将此FPGA程序与电机部分及风机部分程序相连接,实时模拟了一次双馈电机并网及并网后运行的连续过程,通过对此过程中励磁变流器的运行特性分析验证了此FPGA实现的合理性及正确性。

Abstract: Real-time simulation of power electronic components is hard to be conducted on common simulation platform due to the high requirement of the simulation step size and the calculation accuracy. Taking doubly-fed induction generator (DFIG) with excitation realized by dual-PWM converter as research object, the hardware real-time simulation on converter model and its control system are conducted on field-programmable gate array (FPGA). Then the FPGA program is connected to the simulation program of wind turbine and DFIG, and a continuous process before and after the grid with the connection of DFIG is simulated in real time. The rationality and correctness of the FPGA implementation are verified by the analysis of the dynamic operation performance of the converter in the simulation process.
