多虚拟同步机(VSG)并联系统存在功率与频率振荡风险,威胁着系统运行的安全性和稳定性。现有小信号建模方法结构复杂,难以全面揭示系统在不同扰动下的功频响应特性。为此,首先基于机电比拟原理,在不同扰动条件下构建了多VSG并联系统的机械导纳模型,推导了系统功频响应的传递函数。其次,将基于该传递函数的频域响应结果与MATLAB/Simulink时域仿真结果进行对比分析,揭示并验证了多VSG并联系统在不同参数下的功频振荡特性及其变化规律。最后,通过2台100 kVA-VSG并联系统的实验,进一步验证了所建机械导纳模型和相关理论分析的正确性。
Multi-virtual synchronous generator (VSG) parallel systems face the risk of power and frequency oscillations
which threaten the safety and stability of system operation. Existing small-signal modeling methods are structurally complex and cannot fully reveal the power-frequency response characteristics of the system under different disturbances. To address this issue
first
based on the electromechanical analogy principle
a mechanical admittance model of a multi-VSG parallel system is constructed under different disturbance conditions
and the transfer function of the system's power-frequency response is derived. Second
the frequency-domain response results based on this transfer function are compared and analyzed with time-domain simulation results from MATLAB/Simulink
revealing and validating the power-frequency oscillation characteristics and their variation laws of the multi-VSG parallel system under different parameters. Finally
experiments on a two-unit 100 kVA VSG parallel system further verify the correctness of the established mechanical admittance model and the associated theoretical analysis.
