【摘要】：利用潮流能發(fā)電技術(shù)解決偏遠(yuǎn)海島的能源供應(yīng)和海洋水下監(jiān)測(cè)儀器供電問(wèn)題意義重大。潮流能作為一種清潔能源,不會(huì)對(duì)環(huán)境造成污染與破壞,并具有儲(chǔ)量大、發(fā)電規(guī)律可預(yù)測(cè)等優(yōu)點(diǎn),近年來(lái)潮流能的開(kāi)發(fā)利用已成為可再生能源研究的熱點(diǎn)。潮流能發(fā)電裝置大多獨(dú)立運(yùn)行,離散分布在無(wú)人值守區(qū)域,對(duì)保證設(shè)備高效運(yùn)行和及時(shí)維護(hù)帶來(lái)不便。為保證潮流能發(fā)電裝置穩(wěn)定、可靠的運(yùn)行需配備實(shí)時(shí)或準(zhǔn)實(shí)時(shí)監(jiān)控系統(tǒng)。當(dāng)前針對(duì)潮流能發(fā)電技術(shù)的研究呈現(xiàn)多樣化發(fā)展,各種新型潮流能發(fā)電裝置層出不窮,但與之配套的遠(yuǎn)程監(jiān)控系統(tǒng)則在數(shù)據(jù)采集的精準(zhǔn)度、通信鏈路的傳輸速度及數(shù)據(jù)存儲(chǔ)的可靠性等方面都存在嚴(yán)重不足。目前監(jiān)控系統(tǒng)基本上是由潮流能發(fā)電裝置的研制單位自行設(shè)計(jì),其前端數(shù)據(jù)采集使用霍爾元件與AD電路相結(jié)合的方式,數(shù)據(jù)采集電路的通用性沒(méi)有保證;數(shù)據(jù)遠(yuǎn)程通信鏈路采用藍(lán)牙與無(wú)線電臺(tái)的方式,在數(shù)據(jù)傳輸過(guò)程中容易產(chǎn)生丟數(shù)現(xiàn)象,并且傳輸距離十分有限;監(jiān)控?cái)?shù)據(jù)采用文本格式或者Excel表格進(jìn)行存儲(chǔ)數(shù)據(jù)會(huì)造成數(shù)據(jù)查詢、分析和管理的不便,一旦文件損壞,甚至?xí)斐蓴?shù)據(jù)永久性丟失。針對(duì)這種情況,本文設(shè)計(jì)了一種通用的潮流能發(fā)電裝置遠(yuǎn)程實(shí)時(shí)監(jiān)控系統(tǒng),主要完成了如下研究工作:1.遠(yuǎn)程監(jiān)控系統(tǒng)前端數(shù)據(jù)采集模塊,采用多功能電力儀表進(jìn)行參數(shù)測(cè)量,這些智能電力儀表經(jīng)過(guò)國(guó)家有關(guān)計(jì)量部門(mén)校準(zhǔn),其輸出結(jié)果的標(biāo)準(zhǔn)性和權(quán)威性有保障。前端處理機(jī)與各個(gè)電力儀表之間通過(guò)RS-485連接,使用MODBUS-RTU協(xié)議讀取上述儀表的參數(shù)完成數(shù)據(jù)采集。最后將數(shù)據(jù)采集電路進(jìn)行集成化和模塊化處理,以便其他潮流能發(fā)電裝置直接使用。2.針對(duì)監(jiān)測(cè)數(shù)據(jù)傳輸過(guò)程中存在的數(shù)據(jù)丟失和速率偏慢等問(wèn)題,設(shè)計(jì)了兩種無(wú)線數(shù)據(jù)傳輸方案,其一是基于ARM開(kāi)發(fā)板與3G路由器組成的無(wú)線數(shù)據(jù)傳輸模塊,其二是以SIM300模塊為基礎(chǔ)部件,設(shè)計(jì)完成的無(wú)線數(shù)據(jù)傳輸模塊,最后通過(guò)比較兩種方案的優(yōu)缺點(diǎn),確定選擇第一種方案作為本套監(jiān)控系統(tǒng)的首選方案,另一種方式作為備用。3.提出使用數(shù)據(jù)庫(kù)服務(wù)器存儲(chǔ)監(jiān)測(cè)數(shù)據(jù),解決數(shù)據(jù)存儲(chǔ)的可靠性和長(zhǎng)久保存問(wèn)題,并使用LabVIEW設(shè)計(jì)了潮流能發(fā)電裝置實(shí)時(shí)監(jiān)控程序,通過(guò)開(kāi)放數(shù)據(jù)庫(kù)連接(Open Database Connectivity,ODBC)訪問(wèn)潮流能發(fā)電裝置的實(shí)時(shí)工作狀態(tài),顯示直觀方便。該遠(yuǎn)程監(jiān)控系統(tǒng)實(shí)際應(yīng)用于本課題組研制的15KW自變距潮流能發(fā)電裝置以及5KW模塊化潮流能發(fā)電裝置上并始終穩(wěn)定工作,證明了該系統(tǒng)在實(shí)用性、穩(wěn)定性、可靠性等方面達(dá)到了實(shí)際應(yīng)用要求,對(duì)國(guó)內(nèi)外其他潮流能裝置的遠(yuǎn)程監(jiān)控系統(tǒng)設(shè)計(jì)有借鑒和參考價(jià)值。
[Abstract]:It is of great significance to use tidal power generation technology to solve the problems of energy supply in remote islands and the power supply of underwater monitoring instruments. As a kind of clean energy, tidal energy can not cause pollution and damage to the environment, and has the advantages of large reserves and predictable rules of power generation. In recent years, the development and utilization of tidal energy has become a hot topic in the research of renewable energy. Most of the power generation devices operate independently and are distributed in unattended areas. It is inconvenient to ensure the efficient operation and timely maintenance of the equipment. In order to ensure the stability of power generation equipment, reliable operation needs to be equipped with real-time or quasi-real-time monitoring system. At present, the research on power flow power generation technology is diversified, and a variety of new power generation devices are emerging in endlessly, but the corresponding remote monitoring system is in the accuracy of data acquisition. The transmission speed of communication link and the reliability of data storage are seriously deficient. At present, the monitoring system is basically designed by the research and development unit of the power flow power generation device. The front end data acquisition uses the combination of Hall element and AD circuit, and the generality of the data acquisition circuit is not guaranteed. Bluetooth and radio are adopted in data remote communication link. It is easy to lose number in the process of data transmission, and the transmission distance is very limited. Monitoring data using text format or Excel table to store data will cause inconvenience of data query, analysis and management. Once the file is damaged, it will even cause permanent loss of data. In view of this situation, this paper designs a universal remote real-time monitoring and control system for power flow power generation device, and mainly completes the following research work: 1. The front-end data acquisition module of remote monitoring and control system adopts multi-function electric power instruments to measure parameters. These intelligent power instruments are calibrated by relevant national metering departments and the output results are guaranteed to be standard and authoritative. The front-end processor is connected with each power instrument by RS-485, and the parameters of the instrument are read by MODBUS-RTU protocol to complete the data acquisition. Finally, the data acquisition circuit is integrated and modularized, so that other power generation devices can be directly used. 2. 2. Aiming at the problems of data loss and slow data rate in the process of monitoring data transmission, two wireless data transmission schemes are designed. One is the wireless data transmission module based on ARM development board and 3G router. The other is the design of wireless data transmission module based on SIM300 module. Finally, by comparing the advantages and disadvantages of the two schemes, we choose the first scheme as the preferred scheme of the monitoring system, and the other as the backup. 3. This paper proposes to use database server to store monitoring data, to solve the problem of reliability and long-term storage of data storage, and to design a real-time monitoring program of power flow power generation device by using LabVIEW. Through open database connection, Open Database Connectivity C (ODBC) is used to access the real-time working state of power flow power generation device, and the display is intuitionistic and convenient. The remote monitoring system has been applied to the 15KW self-variable distance power flow power generation device and the 5KW modular power flow power generation device developed by our research group and has always worked stably, which proves that the system is practical and stable. Reliability and other aspects meet the practical application requirements, which has reference and reference value for the design of remote monitoring system of other power flow devices at home and abroad.
