摘要
微型燃气轮机发电(Microturbine Generation,MTG)是微网中一种具有广泛应用前景的分布式发电技术。本文详细介绍了单轴微型燃气轮机发电系统的动态数学模型,并对其在微网中的运行与控制进行研究。本文采用PSCAD/EMTDC仿真软件,对微型燃气轮机发电系统的并网和孤岛运行方式进行仿真,在此基础上研究不同运行方式下的逆变器控制策略以及孤岛运行方式下的负荷跟踪能力。仿真实验结果验证了微型燃气轮机能够根据微网的运行需要灵活的调整控制方式,具有很好的运行特性。
The generation system based on microturbine is one of the most potential and viable distributed generation technology in microgrid.This paper introduces dynamic models of a single shaft MTG.Then we investigate its dynamic behaviors and control strategies within a microgrid.These studies are performed using the PSCAD/EMTDC software package.The simulation of the MTG operation in both grid connected mode and islanding mode are presented.This paper also investigates the inverter control strategies for both operation modes and load following performance in islanding mode.The results demonstrate that the operation and performance of the MTG are capable of adopting different control strategies in the need of the microgrid operation.
