摘要
煤矿井下配电级数多,过流保护无时限导致越级跳闸,造成大面积停电、瓦斯超限,影响矿井安全生产。通过高速数据通信网络使配电系统内各保护控制装置进行快速的数据交换,得到其他线路或元件的实时数据,进而综合判断故障点并选择最有利用于系统稳定和故障隔离的措施跳开相应开关,实现全系统的智能判断,自动化控制。
The coal mine power distribution series and more free time led to leapfrog over current trip,causing widespread power outages,gas gauge,affecting mine safety.High-speed data communication network within the distribution system protection and control devices for rapid data exchange,lines or components by other real-time data,and then integrated to determine and select the most favorable point of failure for the system stability and fault isolation measures corresponding jump switch,system-wide intelligence judgments,automation and control.
