摘　　要： 分布式发电不仅能提高供电的可靠性,同时也为用户及电网带来额外的益处。微型燃气轮机发电系统以其优越的性能被称为最佳的分布式发电,将其引入电网的最后一道防线,重点分析微型燃气轮机在城市电网黑启动中的运用,研究微型燃气轮机在黑启动过程中作为备用电源的特点,对微型燃气轮机空冲变压器所产生的励磁涌流及异步电动机负荷扰动进行仿真研究,结果表明微型燃气轮机在城市电网黑启动中将扮演举足轻重的角色。 Grid connected distributed generation （DG） can not only increase reliability, but also provide additional benefits for consumers as well as utilities. Microturbine （MT） generation system is regarded as the best way of distributed generation for its excellent performance. The paper introduces MT as a back-up power supply during power system black-start. It emphasizes on analyzing the characteristics of the MT as a back-up power supply and simulates the inrush current of the transformer and the load disturbance of asynchronous motor. The results indicate that MT will play an important role in black-start.
