HVDC Light is a new-type HVDC based on Voltage Sourced Converters Technology, applicable to small power transmission. HVDC Light using IGBT build up voltage source converter(VSC) and using microcomputer controlling PWM control technology, with simple operation pattern and output wave. The VSC technology have many more superiorities, such as small cubage, strong function, decreasing filter device an simplifying conversation structure. For these reasons, this technology is named HVD Light. Besides the superiorities of traditional HVDC, HVDC Light can be used for supplying to the isolated and distanced load, economically transmitting power to center load and connecting separated sources. Also, the control method of HVDC Light is much more flexible and multivariate. The voltage drop in the transmission line will be decrease and the voltage quality will be increased by using HVDC Light technology. In this paper, the control method and its application of HVDC Light will be most studied. Firstly, the mathematical model of HVDC Light and the DQ model of VS are established. Then the structure of control system and the basic control method are introduced for designing VSC controllers. The VSC controller is based on dual-close-loop control strategy. For validating the VSC controller, the MATLAB simulation models are established. It is demonstrated by simulation results that the controller is convenient flexible and efficient; moreover, the power flow and the stability of HVDC Light system can be controlled easily, all the b- sic control method can be achieved by this controller.
