结合微网和煤矿井下局扇供电的特点,着重讨论了其设计、运行、控制等问题。通过微网对局扇供电的实例,指出微网的设计要遵循安全可靠、功率平衡、运行灵活的原则;分析了微网的结构和运行方式,对于并网运行模式、孤网运行模式进行了详细说明,提出在不同的运行模式下微网设计的特点。 Combined with the characteristics of microgrid and coal mine fan power supply, the problems of design, operation and control are discussed. Through the example of micro-grid fan power supply, it is pointed out that the design of micro-grid should follow the principle of safe, reliable, power balance and flexible operation. The structure and operating mode of micro-grid are analyzed. For grid-connected operation mode and isolated operation mode Detailed description, proposed in different modes of operation of the characteristics of micro-network design.
