Abstract This paper discusses the integration of wind energy system in Derna, Libya to the main grid of General Electricity company of Libya (GECOL) through a back-to-back converter. The machine side converter is used to regulate the AC and DC voltages while the grid side converter is used to control the active and reactive power supplied by the wind energy system. To achieve a relatively simple and decoupled control, the controllers are implemented in the QD reference frame. The proposed system is simulated using MatLab/Simulink environment. The simulation results show the rapid response of the control system in following the commanded active and reactive power commands and the robustness of the proposed system to the changes in operating conditions.

通过背靠背变流器并网的风能系统

摘要 本文讨论了利比亚德尔纳的风能系统通过背靠背变流器并入利比亚通用电力公司（GECOL）主电网的问题。机侧变流器用于调节交流和直流电压，而网侧变流器用于控制风能系统提供的有功和无功功率。为了实现相对简单和解耦的控制，控制器在 QD 参考系中实现。建议的系统使用 MatLab/Simulink 环境进行仿真。仿真结果表明，控制系统在遵循有功功率和无功功率命令时的快速响应以及所提出的系统对运行条件变化的鲁棒性。
