介绍了国内外微电网发展的现状,结合内蒙古大盛魁商业区示范性工程实例,提出了以燃气轮机为微电源的微型电网典型设计原则,并研究了微网系统的运行、控制和保护技术。以仿真实验为辅,制定了微电网控制与保护策略,以保证三联供系统冷、热、电多能源的供给可靠性。仿真结果证明了该控制方式与保护策略的有效性。
This paper analyzes the microgrid development of domestic and abroad in the current situation. According to Inner Mongolia Dashengkui commercial demonstration project,the paper proposes the typical microgrid design principle which supply the energy from gas turbine, studies the operation mode,control mode and protection coordination, and develops the control and protection strategies supplemented by simulation experiments. This system can ensure the cooling,heating and electricity energy supply reliability. The result of simulation shows the effectiveness of the protection strategies and control method.
