【摘要】：母線艙是GIS(Gas Insulated Switchgear,氣體絕緣密封式設(shè)備)組合電器的重要構(gòu)成組件,安裝在母線艙上,在安裝的過程中,使用波紋補(bǔ)償器來對設(shè)備生產(chǎn)和安裝過程中造成的誤差進(jìn)行必要的補(bǔ)償。波紋補(bǔ)償器在環(huán)境溫度出現(xiàn)劇烈的變化的情況下,如果波紋補(bǔ)償器在頻繁的拉伸與壓縮等外力作用下進(jìn)行變化,極易出現(xiàn)金屬疲勞,從而不能對誤差進(jìn)行充分的補(bǔ)償,在這種情況下,母線艙極易出現(xiàn)艙體焊縫開裂、氣體泄漏等故障,影響電網(wǎng)運行安全。因此,為了保障變電站安全穩(wěn)定運行,本文旨在構(gòu)建一套對GIS母線艙形變位移監(jiān)測并對超閾值的形變進(jìn)行預(yù)警的在線實時監(jiān)測系統(tǒng),用于實時監(jiān)測GIS母線艙伸縮節(jié)的位移形變等信息,分析其成因和危害,對超過設(shè)備允許的變形和應(yīng)力做出預(yù)警,保證GIS組合電器母線艙安全穩(wěn)定可靠運行。在母線艙位移形變監(jiān)測系統(tǒng)開發(fā)和建設(shè)實施中,作者除了在系統(tǒng)建設(shè)的前期參與了系統(tǒng)架構(gòu)的設(shè)計工作以外,對系統(tǒng)需求的了解、總結(jié)和系統(tǒng)原型界面設(shè)計等工作內(nèi)容也進(jìn)行了積極的參與;在系統(tǒng)的編碼實現(xiàn)過程中,客戶端設(shè)備管理模塊、監(jiān)控管理模塊、客戶端連接管理模塊、位移數(shù)據(jù)接收和管理模塊、報警模塊和數(shù)據(jù)分析模塊的編碼實現(xiàn)也是有作者獨立或者參與下完成的。參與對數(shù)據(jù)庫的設(shè)計,參與了組合式位移信息采集傳感器模塊的設(shè)計與開發(fā)。在測試階段,筆者參與完成了系統(tǒng)的功能測試和所有模塊的單元測試。本文所設(shè)計的母線艙位移形變監(jiān)測系統(tǒng)主要由組合式位移信息采集傳感器模塊、位移信息接收與發(fā)送模塊和母線艙位移形變監(jiān)測控制系統(tǒng)三個部分組成。組合式位移信息采集傳感器模塊通過傳感器組,采集表征GIS組合電器母線艙運行狀態(tài)的部分信息,并做初步處理,同時設(shè)計便于安裝、調(diào)試和運維的夾持裝置;位移信息接收與發(fā)送模塊將Zigbee無線傳感網(wǎng)絡(luò)控制器技術(shù)應(yīng)用在智能終端技術(shù)平臺,實時歸集各項監(jiān)測數(shù)據(jù),并通過無線網(wǎng)絡(luò)傳輸技術(shù),將歸集后的信息發(fā)送到母線艙位移形變監(jiān)測控制系統(tǒng)的數(shù)據(jù)處理單元;母線艙位移形變監(jiān)測控制系統(tǒng)采用B/S模式構(gòu)建,具有終端管理、實時數(shù)據(jù)監(jiān)測、實時數(shù)據(jù)曲線顯示、歷史數(shù)據(jù)顯示、數(shù)據(jù)分析及異常情況報警提醒等功能。目前,該系統(tǒng)處于試運行階段,筆者所負(fù)責(zé)的模塊功能穩(wěn)定、運行正常,達(dá)到了預(yù)期目標(biāo)。
[Abstract]:Busbar compartment is an important component of GIS(Gas Insulated switch gear. The corrugated compensator is used to compensate the errors caused during the production and installation of the equipment. The corrugated compensator changes dramatically in the ambient temperature. If the corrugated compensator changes under the action of external forces such as frequent tension and compression, it is easy to appear metal fatigue, so that the error can not be fully compensated. In this case, the busbar cabin is prone to crack in the hatch weld. Therefore, in order to ensure the safe and stable operation of substation, this paper aims to construct an on-line real-time monitoring system for monitoring deformation displacement of GIS busbar cabin and warning the deformation over threshold. It is used to monitor the displacement and deformation information of the GIS busbar cabin telescopic joint in real time, analyze its cause and harm, and make early warning of the deformation and stress that exceed the equipment allowable. In order to ensure the safe, stable and reliable operation of the GIS combined electrical busbar cabin, in the development and construction of the system, the author not only participated in the design of the system architecture in the early stage of the system construction, but also understood the requirements of the system. In the coding process of the system, the client equipment management module, the monitoring management module, the client connection management module, the displacement data receiving and managing module, the client connection management module, the displacement data receiving and managing module, etc. The coding implementation of alarm module and data analysis module is also completed by the author independently or with the participation of the author. It participates in the design of database and the design and development of the combined displacement information acquisition sensor module. The author participated in the function test of the system and the unit test of all modules. The displacement information receiving and transmitting module and the bus compartment displacement monitoring and controlling system are composed of three parts. The combined displacement information acquisition sensor module collects some information about the running state of the GIS composite electrical busbar cabin through the sensor group. At the same time, the clamping device is designed to be convenient for installation, debugging and operation. The displacement information receiving and transmitting module applies the Zigbee wireless sensor network controller technology to the intelligent terminal technology platform, and gathers the monitoring data in real time. Through the wireless network transmission technology, the collected information is sent to the data processing unit of the monitor and control system of the bus slot displacement and deformation, the system is constructed by B / S mode and has terminal management. The functions of real-time data monitoring, real-time data curve display, historical data display, data analysis, and alarm and warning of abnormal situation are all functions. At present, the system is in the stage of trial operation, and the function of the module the author is responsible for is stable and running normally. The target was achieved.
