【摘要】：变电站是电力系统的一个重要环节,保障变电站中一次设备和二次设备的安全运行,关系到整个电网运行的可靠性及稳定性。变电站环境是影响变电站设备工作状态及工作性能的重要因素。目前变电站环境监测存在监测因子单一、信息化程度不高、人员工作强度大等问题,特别是对温湿度的监测还处于人工巡视记录模式,不能实时监测,易产生人为误差,不能在温湿度超限的第一时间发现异常,造成设备运行的安全隐患。本文结合计算机通信技术、自动化技术以及电子技术,提出了一种基于安卓操作系统的变电站环境监测系统。该系统由下位机硬件终端及上位机软件组成,下位机以单片机为核心,具有温湿度检测、显示、判断、与上位机通信等功能;上位机软件是在PC机上搭建安卓开发环境,安装SDK软件,采用JAVA语言开发编写APP应用程序。该APP软件具有实时显示变电站温湿度参数、下位机控制、参数设置等功能。根据所设计的变电站环境监测系统方案,完成了上位机及下位机的设计及样机制作,并进行了下位机传感器性能测试、控制性能测试以及系统整体测试。针对测试过程中发现的传感器测量数据误差较大问题,通过将中值滤波引入到程序设计中提高测量精度,改进后的测量数据显示温度误差最小为0 ℃,最大为0.4 ℃;湿度测量误差最小为0 RH%,最大为3RH%。最后将上位机软件安装在智能手机上,进行了系统整体测试。测试结果表明,该系统数据测量较为准确,APP软件显示正常,数据异常时APP报警正常,控制性能良好。所研究开发的变电站环境监测装置,具有一定的工程应用价值。
[Abstract]:Substation is an important link in power system. It is related to the reliability and stability of the whole power network to ensure the safe operation of the primary and secondary equipments in the substation. Substation environment is an important factor affecting the working state and performance of substation equipment. At present, there are some problems in substation environmental monitoring, such as single monitoring factor, low information level, large working intensity, etc. Especially, the monitoring of temperature and humidity is still in the manual inspection record mode, which can not be monitored in real time, and it is easy to produce human error. Can not be found in the temperature and humidity beyond the first time abnormal, resulting in equipment operation safety risks. A substation environment monitoring system based on Android operating system is presented in this paper, which combines computer communication technology, automation technology and electronic technology. The system is composed of the hardware terminal of the lower computer and the software of the upper computer. The lower computer takes the single chip computer as the core and has the functions of temperature and humidity detection, display, judgment, communication with the upper computer, etc. The upper computer software is to build the Android development environment on the PC computer, install the SDK software, and use JAVA language to develop and write the APP application program. The APP software can display the temperature and humidity parameters of substation, control the lower computer and set the parameters in real time. According to the design of substation environment monitoring system, the design and prototype of upper computer and lower computer are completed, and the performance test, control performance test and whole system test of lower computer sensor are carried out. Aiming at the large error of sensor measurement data found in the testing process, the median filter is introduced into the program to improve the measurement accuracy.
