单周期控制在分布式发电系统的应用研究

Study and Implementation of One Cycle Control in Distributed Power Generation System

比较了4种电路单周期控制方程,得到了电压源型变换器的单周期通用控制方程,并引入锁相环移相技术设计了其通用的单周期控制电路,可方便地实现4种电路的单周期控制。通过仿真分析验证了控制电路的适用性和正确性。该电压源型变换器的单周期通用控制电路,可以方便地在一套控制器中实现不同的功能应用,有效地提高了开发效率。

The four one cycle control( OCC) control equations were compared,then the general OCC control equation was achieved and the general OCC control circuit was realized with the phase-locked loop and phase-shift technology. The feasibility and correctness of the proposed circuit were verified by the simulation results. The proposed circuit can simply realize the four application in one controller,so the development efficiency can be increased greatly.
