摘要
轻型高压直流输电系统(HVDC Light)具有广阔的应用前景,为实现HVDC Light输送有功、无功功率的独立控制,建立了在同步旋转d～q坐标轴下系统的数学模型,设计了双闭环解耦控制方案,并重点介绍了电流内环和功率外环比例积分(PI)调节器的设计以及参数整定方法。最后利用仿真软件Matlab/Simulink对HVDC Light系统的功率控制进行仿真分析,验证了数学模型的正确性和功率控制器的有效性。
With the advance of power electronic technology,HVDC light transmission based on voltage-source IGBT power converters have been increased rapidly.In order to realize the independent control of the active and reactive power,this paper has built the mathematical model of a HVDC light system in a d～q reference frame.According to the double closed-loop decoupling control scheme,a PI controller design and parameter setting method of the current inner loop and power outer loop is detailed introduced.And a simulation model of a HVDC light system based on the Matlab/Simulink is also built.The result of the simulation successfully verified the effectiveness of the proposed model and controller.
