将PWM整流器的直接功率控制方法用于电压型超导储能系统的电压源型换流器,给出了新的开关矢量表,并提出了斩波器的直接功率控制方法。文中的电压源型换流器和斩波器的直接功率控制方法以有功功率为纽带,可对超导储能系统进行一体化的功率控制。仿真结果表明,该控制方法具有良好的控制性能,十分适用于电压型超导储能系统。

In this paper, the direct power control method of PWM rectifiers is applied in the voltage source converter of the voltage type superconducting magnetic energy storage （SMES） system, a new switching vector table is used in the proposed control method and a direct power control methods for SMES chopper is also proposed. By means of active power, the direct power control method of voltage source converter and chooper is unified and can be used for SMES system. Simulation results show that the above-mentioned unified direct power control method possesses good control performance, so it is extremely suitable to voltage type SMES system.
