摘　　要：风力的间歇性导致风电机组输出功率波动,会影响风机并网。将超级电容储能系统应用在风电系统中调节输出,使注入电网的功率平稳。超级电容器储能技术在短时大功率应用中具有良好的经济性,符合微电网运行对瞬时功率平衡控制的要求。介绍了超级电容模型,双向直流变换器的原理及互补PWM控制技术,同时采用电流前馈解耦和有功无功算法控制并网逆变器。设计基于超级电容的风力发电功率调节系统模型,并仿真验证系统的正确性。The intermittent nature of wind led to fluctuations in the output power of the wind turbine, thus affecting the fan grid.Super capacitor energy storage system applies in the wind power system to regulate the output so smooth power injected into the grid.Super capacitor energy storage technology has a good economy in the short-term high-power occasions, in line with the requirements of the microgrid operation of the instantaneous power balance control The super capacitor model, the principle of bi-directional DC-DC converter and the complementary PWM control technology were described, while using the current feedforward decoupling and the PQ algorithm control grid inverter. The design is based on the wind power generation of super capacitor to adjust the system model.Simulation verifies the correctness of the system.
