摘要

采用考虑电压影响的SRF-PLL模型,建立了工作在下垂模式下的电流源变换器的状态空间模型。用两种不同的频率估计对线性和非线性模型进行了仿真。由于频率估计的存在,非线性仿真中产生了不稳定性,并在线性模型中得到了验证。对线性模型和非线性模型进行了比较。

SRF-PLL Influence on the Stability of a Current Source Converter in Droop Mode
A SRF-PLL model considering voltage influences is used to develop a state-space model of a current source converter operating on droop mode. The linear and non-linear models are simulated with two different frequency estimations. Due to the frequency estimation, an instability arises in the non-linear simulation and it is verified in the linear model. Comparisons are made between the linear and non-linear models.
