1. Aiming at the study actuality of fan performance monitoring system and analysis of fan performance curve changes affected by inlet - box and the different fixed - angles of guide blades in the course of installation , a fan flow monitoring model based on rbfnn in whole flow zone was established in this thesis . in the model , the method of no throttle and fan performance curve were used as basis . and on the basis of that model , fan performance curves of 4 - 73no . 8d were approached with experimental data of different speed , different opening - angles of guide blade and different resistance of pipeline , the precision and the error law of model were studied
   本文針對(duì)電站風(fēng)機(jī)性能監(jiān)測(cè)系統(tǒng)研究較少的現(xiàn)狀，在實(shí)驗(yàn)的基礎(chǔ)上分析了現(xiàn)場(chǎng)加裝進(jìn)氣箱和由于安裝造成的導(dǎo)流器葉片開(kāi)度不一致對(duì)風(fēng)機(jī)性能曲線的影響，并在此基礎(chǔ)上采用無(wú)節(jié)流方法測(cè)量流量，以風(fēng)機(jī)調(diào)節(jié)性能曲線為依據(jù)，建立了基于徑向基函數(shù)( rbf )神經(jīng)網(wǎng)絡(luò)的風(fēng)機(jī)流量全程監(jiān)測(cè)模型；以實(shí)驗(yàn)室4 - 73no . 8d離心風(fēng)機(jī)為研究對(duì)象，探討了rbf神經(jīng)網(wǎng)絡(luò)差壓模型在變轉(zhuǎn)速、變導(dǎo)流器開(kāi)度和變管網(wǎng)阻力等工況下的應(yīng)用精度和誤差分布規(guī)律；最后用visualc + +語(yǔ)言開(kāi)發(fā)了風(fēng)機(jī)性能在線監(jiān)測(cè)系統(tǒng)。
