摘要：

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. © 2020, Electric Power Automation Equipment Editorial Department.
