摘要
以超级电容器作为储能元件设计了超级电容器储能并网系统,并将无差拍控制应用到超级电容器储能系统的并网控制中,能实现对并网系统的有功功率和无功功率的综合快速补偿,有效地改善了并网系统的电能质量和稳定性。通过仿真验证了所提方法的正确性,结果表明:所设计的并网系统控制简单、灵活性强,随时可以实现无冲击并网,可提高系统效率,可控性良好。
This paper presented the super capacitor storage grid cut-in system based on the super capacitor. Deadbeat control method was applied in the grid cut-in control. The system designed can compensate the active power and reactive power of the grid-in system in order to improve the power quality and stability of the grid. The correctness of the method presented was verified by s/mulation, the simulation results validated the feasibility of the strategy and showed that the deadbeat control strategy has many merits： it is easy to control the grid cut-in process, the cut-in process is flexible and responds quickly, the cut-in control without current impulsion, the power factor is high and is controllable.
