  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

    本文針對電站風機性能監測系統研究較少的現狀,在實驗的基礎上分析了現場加裝進氣和由於安裝成的導流器葉片開度不一致對風機性能曲線的影響,並在此基礎上採用節流方測量流量,以風機調節性能曲線為依據,建立了基於徑向基函數( rbf )神經網路的風機流量全程監測型;以實驗室4 - 73no . 8d離心風機為研究對象,探討了rbf神經網路差壓型在變轉速、變導流器開度和變管網阻力等工況下的應用精度和誤差分佈規律;最後用visualc + +語言開發了風機性能在線監測系統。
