【摘要】：温度是反映变电站电力设备状态的重要方面。监测变电设备温度主要是为了记录设备在运行状态下的实时温度,减少安全事故的发生,进而减少对电力系统稳定运行的影响。目前绝大多数变电站点采用的是巡视测温的方式,需要值班员人工测温,如果设备发热处要求的测温频次很高,值班员需要多次手持红外热像仪靠近开关柜去测量设备表面温度,这极大增加了值班员的工作量,也增加了发生安全事故的可能性,而且人工巡检的温度监测精确性差,连续性不高,可能导致异常运行条件下电力设备的故障发生。针对上述问题,本文设计了一种变电站设备无线温度监测系统,该系统可以实现电力设备温度的在线监测,通过设定不同地点的报警温度值,实现对多点的温度采集、分析和报警。根据系统所要实现的功能和技术要求,系统设计结构分为采集层、传输层和应用层。采集层中采用了带ZigBee通信模块的CC2530采集节点,通过DS18B20温度传感器实时采集现场电力设备温度信息,以无线方式发送给传输节点。传输层中采用了以ARM9为核心的S3C2440传输节点,它作为其下温度采集节点组成的ZigBee网络的网关,向下管理和接收采集节点的温度信息,向上通过以太网与远端监控中心进行通信。远端监控中心使用MySQL数据库管理体系的数据库,存放采集节点信息、传输节点信息、电力设备信息等,同时可以设定多点的报警阈值。监控界面的编写使用的是java web开发环境Eclipse,通过配置Tomcat的环境变量、JDK的开发环境变量,使用javaBean、javaScript以及HTML作为工具,将MySQL更新的数据导入到网页上显示。文中给出了采集节点、传输节点的硬件电路和软件实现方案。分析了远端监控中心数据库的访问过程,构建了 MySQL数据库,设计了浏览访问界面。最后,对数据库的运行和访问界面进行了测试,结果表明可以实现温度的存储、显示和查询。最后,本文对研究工作完成了总结,还针对移动终端APP监测软件的开发和以及实现温度的预警功能进行了展望。
[Abstract]:Temperature is an important aspect to reflect the state of substation power equipment. The main purpose of monitoring the temperature of substation equipment is to record the real-time temperature of the equipment under the operation state, to reduce the occurrence of safety accidents, and then to reduce the influence on the stable operation of power system. At present, most substation sites use the method of inspecting temperature, which requires manual temperature measurement by duty personnel. If the temperature measurement frequency required by the heating place of the equipment is very high, Duty attendants need to hold infrared thermal imagers several times to measure the surface temperature of the equipment near the switchgear, which greatly increases the workload of duty guards and the possibility of safety accidents. Moreover, the temperature monitoring accuracy of manual inspection is poor. The continuity is not high, which may lead to the fault of power equipment under abnormal operation conditions. In order to solve the above problems, this paper designs a wireless temperature monitoring system for substation equipment. The system can realize the on-line monitoring of power equipment temperature. By setting the alarm temperature value of different locations, the temperature collection of multiple points can be realized. Analysis and alarm. According to the functions and technical requirements of the system, the system design structure is divided into collection layer, transmission layer and application layer. CC2530 acquisition node with ZigBee communication module is used in the collection layer. The temperature information of field power equipment is collected in real time by DS18B20 temperature sensor and sent to transmission node by wireless mode. In the transport layer, S3C2440 transmission node, which is based on ARM9, is used as the gateway of ZigBee network composed of temperature acquisition nodes. It manages and receives the temperature information of the collection nodes down and communicates with the remote monitoring center through Ethernet. The remote monitoring center uses MySQL database management system to store node information, transmit node information, power equipment information, etc. At the same time, multi-point alarm threshold can be set. Monitoring interface is written using java web development environment Eclipse, by configuring Tomcat environment variables of JDK development environment variables, using javaBeaner javaScript and HTML as tools, the java web updated data will be imported to the web page to display. In this paper, the hardware circuit and software implementation of acquisition node and transmission node are given. The accessing process of remote monitoring center database is analyzed, MySQL database is constructed and browsing interface is designed. Finally, the running and accessing interface of the database are tested, and the results show that the temperature storage, display and query can be realized. Finally, the research work is summarized, and the development of mobile terminal app monitoring software and the realization of temperature warning function are prospected.
