摘要
提出一种模拟晶闸管控制电抗器(thyristor controlled reactor,TCR)谐波产生特性的新模型。该模型把TCR的时域非线性特性变换成一个频域线性导纳矩阵。该矩阵把TCR的谐波电压、电流耦合在一起,没有任何近似,且该矩阵是一个常量,不随系统谐波参数变化。所提出的模型为电力系统谐波潮流的计算开辟了一个新思路,通过计算机仿真的波形对比验证了模型的精确性。
This paper proposes a new method to model the harmonic generating characteristics of thyristor controlled reactor （TCR）. The model transforms the time domain nonlinear characteristics of the TCR into a frequency domain linear admittance matrix. The matrix couples the TCR harmonic voltages and currents without any approximation and it does not vary with the harmonic conditions of the system. The proposed model opens a new way to conduct harmonic power flow studies. This paper presents the development and characteristics of the model. Computer simulation results confirmed the model accuracy.
