摘要
煤矿电力监控系统是对煤矿井上、井下高(低)压开关供电、电力保护装置、调度自动化等集成一体进行监测监控的电力自动化系统。本文对井下电力监控分站与主站通讯数据接口和通讯协议标准进行了分析研究,重点研究了煤矿电力监控分站与主站之间硬件通讯接口类型、通讯协议标准、电力监控分站与保护器、监控主站与监控分站交换过程以及高低压通讯装置通讯点表定义等内容,研究表明:通过约定电力监控分站与主站之间的硬件接口与通讯接口协议,可有效实现各种类型数据参数接入和集成,实现煤矿井下供电系统和供电各设备的在线数据监测、远程控制、实时报警、数据统计分析、运行安全保护、用电计量管理等功能,实现井上下变电所无人值守智能监控管理,为智能矿山建设提供基础保障。
Coal mine power monitoring system is a power automation system that monitors and supervises the power supply of the integration of high(low)voltage switches,power protection devices and dispatching automation in coal mines.In this paper,the communication data interface and communication protocol stan⁃dard between underground power monitoring substation and master station are analyzed and studied,focusing on the hardware communication interface type between coal mine power monitoring substation and master sta⁃tion,communication protocol standard,the exchange process between power monitoring substation and protec⁃tor,monitoring master station and monitoring substation,and the definition of communication point table of high and low voltage communication device.The study shows that by agreeing the hardware interface and communication interface protocol between the power monitoring substation and the master station,various types of data parameters can be effectively accessed and integrated to realize online data monitoring,remote control,real-time alarm,data statistical analysis,operational safety protection,electricity metering manage⁃ment and other functions of the underground coal mine power supply system and power supply equipment,and to achieve unattended intelligent monitoring and management of the underground substation,providing the foundation for the construction of intelligent mines.
