TDM1.2-030-300概述 在生產(chǎn)同步發(fā)電機(jī)過(guò)程中,為了測(cè)試同步發(fā)電機(jī)的負(fù)荷能力,發(fā)電機(jī)能否得到設(shè)計(jì)效果,都要用一臺(tái)發(fā)動(dòng)機(jī)帶動(dòng)發(fā)電機(jī)進(jìn)行負(fù)載實(shí)驗(yàn),這樣實(shí)驗(yàn)一臺(tái)大功率發(fā)電機(jī)費(fèi)用比較高。隨著電子電力技術(shù)的發(fā)展,我們采用一種新技術(shù),用一臺(tái)異步電動(dòng)機(jī)帶動(dòng)發(fā)電機(jī),再把發(fā)電機(jī)發(fā)出的電送回電網(wǎng)。這種方式操作簡(jiǎn)單可靠,沒(méi)有環(huán)境污染,并且節(jié)省了大量的人力、物力、財(cái)力。 二、 改造 為了使測(cè)試臺(tái)的操作更為TDM1.2-030-300簡(jiǎn)單,合理。我們大膽的對(duì)山東省東營(yíng)勝利油田某一分公司的測(cè)試臺(tái)進(jìn)行了改造。該公司生產(chǎn)的同步發(fā)電機(jī)功率一般為400KW、500KW等規(guī)格,現(xiàn)我們將測(cè)試臺(tái)發(fā)動(dòng)機(jī)改為一臺(tái)630KW變頻電機(jī),并采用我公司DZB100B6300L4B系列變頻器進(jìn)行驅(qū)動(dòng),經(jīng)過(guò)實(shí)踐證明由電動(dòng)機(jī)與同步發(fā)電機(jī)構(gòu)成的對(duì)拖系統(tǒng)效果十分顯著,得到了良好的評(píng)價(jià)。 三、 原理 測(cè)試臺(tái)電路圖:
由上圖可知,TDM1.2-030-300由變頻器驅(qū)動(dòng)電動(dòng)機(jī),再由電動(dòng)機(jī)拖動(dòng)同步發(fā)電機(jī)轉(zhuǎn)子。將同步發(fā)電機(jī)所發(fā) 之電回饋到電網(wǎng),形成一個(gè)能量負(fù)反饋。在同步發(fā)電機(jī)測(cè)試過(guò)程中有時(shí)需要緊急停車,因此我們又采用了制動(dòng)單元,制動(dòng)電阻對(duì)電動(dòng)機(jī)進(jìn)行能耗制動(dòng)。 四、 優(yōu)點(diǎn) 1、 取消了以前測(cè)試臺(tái)所需要的發(fā)動(dòng)機(jī)設(shè)備,減少了設(shè)備投資費(fèi)用。 2、 減省了大量的測(cè)試裝置,減低了故障率。 3、 節(jié)省了大量的人力、物力、財(cái)力,增強(qiáng)了企業(yè)的競(jìng)爭(zhēng)力。 4、 降低了噪音,完全消除了廢氣的排放。 5、TDM1.2-030-300 提高了工作效率,并且操作簡(jiǎn)單可靠。
