【摘要】：伴隨工業(yè)化程度的提高，人們對(duì)電的需求也逐年增加。因此，如何能保證電力的正常供應(yīng)，成為電力維護(hù)人員非常關(guān)心的問題。影響電力正常供應(yīng)的因素有很多，其中電纜接頭過熱在影響電力正常供應(yīng)的因素中占有很大的比重。所以，，對(duì)電纜接頭溫度的監(jiān)測(cè)就顯得尤為重要。 本文將以電纜接頭溫度為研究對(duì)象，以光纖光柵溫度傳感器為基礎(chǔ)，結(jié)合嵌入式系統(tǒng)理論，利用ZigBee無線網(wǎng)絡(luò)通信技術(shù)，建立電纜接頭溫度監(jiān)測(cè)網(wǎng)絡(luò)，以實(shí)現(xiàn)對(duì)電纜接頭溫度監(jiān)測(cè)。 本文采用ZigBee網(wǎng)狀網(wǎng)絡(luò)拓?fù)浣Y(jié)構(gòu)搭建了電纜接頭溫度在線監(jiān)測(cè)系統(tǒng)的硬件平臺(tái)，并對(duì)監(jiān)測(cè)節(jié)點(diǎn)、路由器和協(xié)調(diào)器的硬件電路分別進(jìn)行了設(shè)計(jì)。電路設(shè)計(jì)主要以微處理器CC2530為控制芯片、CC2591為功率放大芯片，絕緣型光纖光柵溫度傳感器YT-PL-01-3000為溫度數(shù)據(jù)采集元件、12位并行輸出的ADS801為模數(shù)轉(zhuǎn)換芯片。并對(duì)電流/電壓轉(zhuǎn)換電路部分進(jìn)行了設(shè)計(jì)。在監(jiān)測(cè)系統(tǒng)軟件方面，分別對(duì)監(jiān)測(cè)節(jié)點(diǎn)、路由器、協(xié)調(diào)器以及上位機(jī)的工作流程進(jìn)行設(shè)計(jì)，并利用虛擬儀器Labview對(duì)上位機(jī)界面進(jìn)行設(shè)計(jì)。 在監(jiān)測(cè)系統(tǒng)硬件平臺(tái)的基礎(chǔ)上，對(duì)獲取的電纜接頭溫度數(shù)據(jù)，分別采用固定門限檢測(cè)算法和溫度變化率檢測(cè)算法對(duì)其運(yùn)算處理，并且以不同的級(jí)別判斷監(jiān)測(cè)區(qū)域的電纜接頭的運(yùn)行狀態(tài)。為了能夠給電力維護(hù)人員提供更多的應(yīng)對(duì)電力突發(fā)事件的時(shí)間，本文又利用卡爾曼預(yù)估值算法對(duì)電纜接頭溫度進(jìn)行預(yù)測(cè)及判別預(yù)警，建立了溫度預(yù)估計(jì)數(shù)學(xué)模型，并利用MATLAB軟件進(jìn)行仿真。仿真結(jié)果表明卡爾曼預(yù)測(cè)算法能夠?qū)﹄娎|接頭溫度預(yù)測(cè)，使電纜接頭的溫度不僅可以實(shí)時(shí)被監(jiān)測(cè)，而且可以提前預(yù)測(cè)電纜接頭的溫度。本文最后又根據(jù)三種算法設(shè)計(jì)報(bào)警規(guī)則，從而使電纜接頭溫度報(bào)警能夠準(zhǔn)確和及時(shí)，為電力維護(hù)人員提供技術(shù)支持，有效的保證電力系統(tǒng)及時(shí)維護(hù)和正常運(yùn)行。
[Abstract]:With the development of industrialization, the demand for electricity is increasing year by year. Therefore, how to ensure the normal supply of electricity has become a problem of great concern to maintainers. There are many factors that affect the normal power supply, among which the overheating of the cable joint occupies a large proportion of the factors that affect the normal power supply. Therefore, it is very important to monitor the temperature of cable joint. In this paper, based on fiber grating temperature sensor and embedded system theory, using ZigBee wireless network communication technology, the cable junction temperature monitoring network is established. In order to achieve the cable joint temperature monitoring. In this paper, the hardware platform of the on-line monitoring system for cable joint temperature is built with the ZigBee mesh network topology. The hardware circuits of the monitoring node, router and coordinator are designed respectively. The circuit is mainly designed with microprocessor CC2530 as control chip CC2591 as power amplifier chip and insulated fiber Bragg grating temperature sensor YT-PL-01-3000 as temperature data acquisition element and 12-bit output ADS801 as analog-to-digital conversion chip. The current / voltage conversion circuit is designed. In the software of monitoring system, the work flow of monitoring node, router, coordinator and host computer are designed, and the interface of upper computer is designed by LabVIEW. On the basis of the hardware platform of the monitoring system, the fixed threshold detection algorithm and the temperature change rate detection algorithm are used to deal with the temperature data of the cable joint, respectively. At the same time, the operation state of cable connector in monitoring area is judged by different levels. In order to provide more time for power maintainers to deal with power emergencies, this paper uses the Kalman prevaluation algorithm to predict and discriminate the cable junction temperature, and establishes a mathematical model of temperature pre-estimation. And use MATLAB software to carry on the simulation. The simulation results show that the Kalman prediction algorithm can predict the temperature of the cable connector, so that the temperature of the cable joint can not only be monitored in real time, but also can be predicted in advance. Finally, the alarm rules are designed according to three algorithms, so that the cable joint temperature alarm can be accurate and timely, provide technical support for the power maintenance personnel, and effectively ensure the timely maintenance and normal operation of the power system.
