摘要: 建立了高压直流输电(HVDC)系统的三相动态相量模型,能快速反映交流系统对称与不对称运行情况下HVDC系统的动态特性。建模过程中,通过分析换流器的开关和换相过程,修正了换流器的开关函数模型;根据直流系统频率特性,使用动态向量理论建立含换流器、直流线路和控制系统的完整的HVDC三相动态相量模型。将HVDC系统三相动态相量模型和电磁暂态模型仿真结果比较,验证了HVDC系统三相动态相量模型的正确性和有效性。

Abstract: A three-phase dynamic phasor (TPDP) model of High Voltage Direct Current (HVDC) systems was proposed. The proposed model could rapidly solve the dynamic characteristics of HVDC systems for AC system symmetrical and asymmetrical operating conditions. Switch functions model of converter was enhanced according to commutation process analysis of the converter. Due to the frequency characteristics analysis results, the TPDP model of HVDC systems with the converter, DC line and controller were established through dynamic phasor theory. Simulation results show that the proposed model is effective and acceptable..
