围绕浙江电网实际应用的自励式MCR开展了基于MATLAB的仿真建模技术研究。对自励式MCR绕组回路交流工作过程和直流励磁过程进行深入解析,数学推导建立了自励式MCR的等效模型。在此基础上,建立了基于双饱和变压器的MCR仿真模型,并详细分析了仿真模型的参数设置。为进一步分析自励式MCR各支路的响应特性,在双饱和变压器仿真方法的基础上,建立了基于多绕组变压器的MCR仿真模型。最后,仿真结果证明了2种仿真建模方法的一致性、正确性和有效性。研究成果可指导MCR设备的实际工程运行,也为后续开展多目标综合无功优化控制研究奠定了基础。

This paper conducts MATLAB-based simulation and modeling on self-excitation MCR applied in Zhejiang power grid. Through in-depth analysis on AC working process of self-excitation MCR winding loop and DC excitation process, an equivalent model of self-excitation MCR is established by mathematical deduction. Accordingly, the double saturated transformer based MCR model is established, and parameter settings are analyzed in detail. Then, to further analyze response characteristics of all winding branches in selfexcitation MCR, a MCR simulation model based on multiple-winding transformer by double saturated transformer simulation method. Finally, the simulation result proves consistency, correctness and effectiveness of the method. The research can provide reference for practical engineering operation of MCR and lay foundation for multi-objective reactive power optimization and control research in the future.
