毕业设计输电线路导线温度检测及动态增容系统设计

毕业论文（设计）题目：输电线路导线温度检测及动态增容系统设计系部名称：专业班级：学生姓名：学号：指导教师：教师职称：20年月日中原工学院信息商务学院毕业论文（设计）I摘要在社会用电量日益增加的今天，如何提高输电线路的输送容量是目前电力部门比较关注的一个问题。本论文从导线温度与输电线路载流量的关系入手，提出了输电线路动态增容的概念，并提出了输电线路动态增容监测系统的思路。通过动态的检测导线温度和环境温度等气象条件分析，确定输电线的输电容量，从而提高导线在一定气象环境下的传输容量。用杆塔监测主分机将导线温度，湿度，风速，日照强度等集中打包为GSM，通过GSM通信模块发送至监测中心。监测中心利用上述信息，结合导线的辐射吸收系数和摩尔根载流量公式计算可允许的载流量，得出了运用动态的检测导线温度和环境气象条件可以提高输电线路的输送容量结论。此外，本次设计软件部分采用单片机C语言进行编程，实现本次设计的控制功能。关键字：输电线路，传输容量，允许温度，导线应力中原工学院信息商务学院毕业论文（设计）IITheDesignofTemperatureTestingForTransmissionlinesanddynamiccompatibilizingsystemAbstractTodaythesocialpowerconsumptiongrowingtodaybyday.Oneofthecurrentlyconcerninelectricitydepartmenthowishowtoimprovethetransmissionlinestransmissioncapacity.Thepaperwhichfromtheheatandwiretransmissionlinesoftherelationshipofthecarryingcapacityputsforwardtheconceptofdynamiccompatibilizingtransmissionlines,andalsoputsforwardthetransmissionlinedynamiccompatibilizingmonitoringsystemofthought.Throughanalysisthedynamictestingtemperatureandenvironmentaltemperature,conductormeteorologicalconditions.wecandeterminethetransmissionwires,soastoimprovethetransmissioncapacityincertainmeteorologicalenvironment.Lordextensionwithtowermonitoringofenvironmentaltemperature,humidity,windspeed,sunshinestrengthforGSM,centralizedpackagedbyGSMcommunicationmodulesenttothemonitoringcenter.Usingtheaboveinformationmonitorcenterofwires,combinedwithradiationabsorptioncoefficientandMorganampacitiesallowstheformulatocalculatethecarryingcapacity.Thetestisobtainedbydynamicconductorandenvironmentaltemperaturemeteorologicalconditionscanimprovethetransmissionlinestransmissioncapacityconclusion.Inaddition,thesoftwarepartofthisdesignadoptssingle-chipmicrocomputerCprogramminglanguage,tomakecontrolfunctionscometrue.Keyword:TransmissionlinesTransmissioncapacityAllowtemperatureWirestress中原工学院信息商务学院毕业论文（设计）III目录1绪论........................................................................................................................................12系统的设计及思路..................................................................................................................22.1设计要求..................................................................................................................22.1.1基本要求...................................................................................................................22.1.2设计的特色...............................................................................................................22.1.3国内外的研究现状...................................................................................................32.2输电线路导线温度检测及动态增容系统的基本结构..........................................42.3输电线路导线温度检测及动态增容系统的工作原理..........................................52.4输电线路导线温度检测及动态增容系统的设计思路..........................................53提高现有输电线路输送容量的基本算法............................................................................63.1影晌导线载流量的因素及各因素对导线载流量影响程度..................................63.2气象因素对载流量的影响......................................................................................94系统硬件设计........................................................................................................................134.1单片机的选择........................................................................................................134.2传感器....................................................................................................................134.2.1温度传感器DS-18B20...........................................................................................144.2.2PHWS/WD风速风向传感器.................................................................................164.2.3湿度传感器.............................................................................................................184.2.4日照强度传感器.....................................................................................................214.3键盘部分................................................................................................................224.4显示部分................................................................................................................224.5电源监控和电源指示部分....................................................................................245系统的软件设计..................................................................................................................265.1主程序流程图..........................................................................................................265.2A/D转换流程图......................................................................................................265.3键盘扫描子程序流程图..........................................................................................286结论......................................................................................................................................29致谢........................................................................................................................................30参考文献....................................................................
