煤矿井下供电设备监控系统设计及实现
|
摘要
本文针对煤矿井下特殊环境中电力运行的实际情况,结合以太网通讯技术、继电保护理论、数字化集成电路技术的设计思想,给出了煤矿井下供电设备监控系统设计方案及实现方法。
目前煤矿井下现有供电设备经常无故障误跳电、有故障没发现、停电后无法及时送电等现象。供电系统的不稳定和电气设备故障(如局扇故障、无计划停电、开关故障、电缆故障等)造成局扇停电,不能及时发现,使采掘工作面瓦斯超限和积聚,随时会引发的恶性事故。另外井下电网传统继电保护在事故预警、保护控制方面技术落后,普遍存在越级跳闸、电压波动引起的大面积停电、漏电保护不可靠、不能及时预警绝缘降低、保护拒动和误动现象;故障无法迅速定位,靠二次故障进行故障定位;保护器功能单一,测量保护精度差,无法实现上下级变电所保护紧密配合。
本文通过对国内外矿井保护技术及数字信号处理(DSP)技术的研究,结合煤矿供电系统现状,提出了符合现场实际的煤矿井下供电设备监控系统设计方案。该方案将系统从构成上分为设备层、变电层、通讯层、监控层四个层次,并就四个层次的设备、功能及特点进行了详细的描述。并着重介绍了保护原理和使用数字信号处理(DSP)技术的强大数据处理能力和高运行速度优越性,分别从保护单元、处理单元、通信单元及遥控方面的软硬件设计和数据采集、处理、传输的方式方法进行了论述。另外为保证系统的可靠性,选择了总线不引出芯片的CPU,使系统在稳定性、可靠性上,都占有一定的优势。
通过对遥控合闸过程的实际操作描述,检验系统的运行状况是否与设计相符,实现煤矿井下供电设备监控系统具备遥测、遥信、遥调、遥控的四遥功能。
The thesis analyses the practical situation of coal mine substations of electric operation, brings the microcomputer coal mine substations protection system design and implementation with Ethernet, protective relay and digital integrated circuit.
The electric devices of coal mine often trip without faults,can’t find with fault and can’t power on in a moment.The power supply system and electrical equipment fault cause part( such as part fault, power failures without plan and cable failure ) power failure and could be found,which cause supercritical gas and make accidents. he excavate no gas and dust, will cause of accident. The traditional relay protection behind the times with the early warning and protection.There are power failure with the voltage fluctuation, unreliable leakage protection,the warning of insulation depression.
Local ventilators often do not work by the unstable power supply system and electric device fault,this phenomenon can also cause supercritical gas and make accidents.
The electric devices protections of coal mine’s backwards in technology often cause large area power loss、protection’s unreliable、wrong fault locating .etc This topic give an improvement scheme,including device layer、transformer layer、communication layer、monitor and control layer. This article brief principles of the power protection、DSP’s application、design plan of the protection unit、CPU unit、communication unit .etc
Based on the above,we can have the more stable and reliable protections.
