摘要
为了研究微型燃气轮机发电系统的低电压穿越能力,建立了包括微型燃气轮机、永磁同步电机、传动链轴系和全功率换流器在内的微型燃气轮机发电系统详细的动态模型,对配电网深度电压跌落情况下的微型燃气轮机发电系统的运行特性在PSCAD/EMTDC中进行了仿真分析,仿真结果验证了模型及控制方式的正确性和有效性,表明微型燃气轮机发电系统在配电网电压跌落期间具备很好的低电压运行能力。
For researching into the LVRT capacity for microturbine generation system, this paper proposes a dynamic model of microturbine generation system, which including microturbine, permanent magnet synchronous generation, modeling of drive train and full power inverter. The operational performance of microturbine generation system is analysised under the depth of DG voltage dip in PSCAD/EMTDC. The simulation results prove that the proposed modes are correctness and effectiveness, and show that the microturbine generation system has been well LVRT capability during the voltage dips.
