| 摘要: |
| 采用伴随离散电路(ADC)建模方法时系统矩阵为常系数矩阵，大幅降低了实时仿真求解的计算量。但是将电力电子开关器件等效为L/C模型会造成其在开关过程中产生振荡现象，从而导致仿真误差。分析了采用ADC建模方法时电力电子器件开关等效导纳Gs与其两端电压、流过电流的误差关系，通过建立损耗函数，研究了最优Gs参数的选取方法；以基于LCL滤波的三相电压源型脉宽调制整流器为例，对Gs参数优化方法进行了离线仿真验证；在现场可编辑门阵列实现仿真模型时，基于Vivado高层次综合工具可以显著简化设计和仿真任务，缩短设计时间并提高可靠性。 |

| Abstract: |
| The ADC(Associated Discrete Circuit) modeling method can greatly reduce the computation burden of real-time simulations owing of the constant system matrix. However, the equivalent L/C model of power electronic devices might cause oscillations in the switching process, which further leads to simulation errors. Firstly, the error relationship between the equivalent admittance Gs of power electronic devices and its voltage and current at both ends obtained from the ADC approaches analyzed. The optimal Gs parameter selection approach is studied by establishing the switching loss function. Subsequently, the LCL filter for three-phase voltage source PWM rectifier is utilized as an example, the optimization method of Gs parameters is verified by offline simulation. Finally, the simulation model is implemented on FPGA(Field Programmable Gate Array),VHLS(Vivado High Level Synthesis) tool significantly simplifies the design and simulation tasks, which further shortens the design time and improves the reliability. |
