| Popis: | The active superconducting current controller (SCC) can adjust the current of the power transmission line effectively, using the method of series voltage compensation. The controllable voltage source type converter is adopted to control the series voltage. This paper presents an improved discretization control method for a series-connected converter. The influence factor of control time delay is introduced for the purpose of improving the control system dynamics. Furthermore, the output error compensation is used to realize the deadbeat control. According to the parameters of dynamic model system laboratory, the SCC and connected system are modeled and the dynamics of the improved control method is validated. |
