【摘要】：稳定可靠的电力监控系统在煤矿的应用,可以提升煤矿供电管理水平,推进现代化矿井的信息化建设。针对目前国内一些煤矿电力监控系统响应速度慢、稳定性不高、对馈电开关控制功能不完善等问题,设计将纳林河二号矿井电力监控系统纳入矿井工业自动化系统,统一进行软硬件平台的建设,使用1000M工业控制环网作为信息传输介质;通过对矿井供电系统的优化设计,为实现系统简单、控制可靠、维护方便的电力监控系统奠定基础;通过对防爆开关智能型综合保护器的选型,统一了RS-485总线通讯协议的接口,解决了电力监控分站与变电所内高低压隔爆开关、移变、照明综保等设备信息传输问题,实现了对井下高低压配电装置的远程控制功能;通过对国内电力监控分站的研究,设计选型具有6路485RTU接口的电力监控分站,并通过485端口的合理分配,使每路485RTU接口接入不超过10路智能综合保护器,在软件设计中使用控制指令优先传输的技术等,极大提高了电力监控系统的响应速度;目前该矿电力监控系统已投入运行,形成了井下各变配电硐室的远程控制和无人值守。本文所述煤矿电力监控系统在矿井的设计与应用与传统设计应用相比,针对性更强、系统考虑更加全面、性能得到了进一步加强。
[Abstract]:The application of stable and reliable power monitoring system in coal mines can improve the level of power supply management in coal mines and promote the information construction of modern mines. In view of the slow response speed and low stability of some domestic coal mine power monitoring systems at present, To solve the problem of imperfect control function of feed switch, the electric power monitoring system of Nalinhe No. 2 mine is integrated into the mine industry automation system, and the software and hardware platform is unified, and the 1000m industrial control ring network is used as the information transmission medium. Through the optimization design of mine power supply system, it lays a foundation for the realization of simple system, reliable control and convenient maintenance, and unifies the interface of RS-485 bus communication protocol by selecting the intelligent comprehensive protector of explosion-proof switch. It solves the problem of information transmission of high and low voltage flameproof switch, shift, lighting and so on, realizes the remote control function of underground high and low voltage distribution device, and through the research of domestic electric power monitoring sub-station, The design and selection of the electric power monitoring sub-station with 6 channels 485RTU interface and reasonable distribution of 485 ports make every 485RTU interface access no more than 10 channels intelligent integrated protector, and use the technology of control instruction priority transmission in the software design, etc. It has greatly improved the response speed of the electric power monitoring system, which has been put into operation at present. The design and application of the power monitoring system in coal mine is more targeted and more comprehensive than the traditional design and application. The performance has been further enhanced.
