Through analyzing relation judgment matrix , consistency matrix , induced matrix and measure matrix , a prediction accelerating method to rectified element is put forword 摘要通過分析判斷矩陣、一致性矩陣、導(dǎo)出矩陣及度量矩陣的關(guān)系,提出一種修改判斷矩陣的預(yù)測加速修正法。
Because central potentials of four y windings in 12 - phase generator are not equal each other and there is no common reference inside the generator , it is difficult to identify the on / off of rectifying elements . in this paper , by using a mathematical model with line voltage substitute for phase voltage , the problem that there is no common reference in the 12 - phase generator with rectifier is solved . based on results of the studies on small prototype , 920kw charging generator applied in a submarine is improved in design , and therefore power oscillation with high magnitude when two generators are operating in parallel 由于十二相發(fā)電機(jī)中四個y繞組的中點(diǎn)電位不等,電機(jī)內(nèi)部沒有公共參考點(diǎn),從而在判斷整流元件導(dǎo)通時,不能象三相同步發(fā)電機(jī)整流系統(tǒng)那樣認(rèn)為陽極電位最高或陰極電位最低的整流元件導(dǎo)通,本文采用了以線電壓代替相電壓建立十二相整流發(fā)電機(jī)的數(shù)學(xué)模型,從而解決了十二相發(fā)電機(jī)無公共參考點(diǎn)的問題。
