1.RAMVBUCapability2.RAMVDriveCharacter3.MVDriveEnergySaving4.IntelligentMotorControl39我國能源面臨的問題我國能源面臨的問題人均能源資源相對不足,資源質量較差,探明程度低。

人均煤炭探明可采儲量僅為世界人均平均值的1/2,石油僅為1/10能源生產消費以煤為主。

原煤在能源消費結構中所占比重為75.6%,給環(huán)境保護帶來極大壓力能源工業(yè)技術水平低下,勞動生產率較低。

我國煤炭工業(yè)職工總數(shù)占世界52%,但煤炭產量占世界總產量21.5%,人均年產煤量僅為世界其他產煤國總計的人均年產煤量的1/5能源資源分布不均,交通運力不足,制約能源工業(yè)發(fā)展。

能源資源西富東貧,給能源運輸帶來壓力,運力不足造成煤炭積壓,制約煤炭工業(yè)發(fā)展,也造成電力供應不足能源供需形式依然緊張。

能源缺口大,拉閘限電,成品由價格上漲,煤炭供應不足能耗水平高,能源利用率低下。

能源系統(tǒng)的總效率不及發(fā)達國家的一半,工業(yè)產品單耗比工業(yè)發(fā)達國家高出30%~90%能源環(huán)境問題日趨嚴重,制約經濟社會發(fā)展。

以城市為中心的環(huán)境污染日趨嚴重,并開始向農村蔓延,生態(tài)破壞的范圍繼續(xù)擴大Copyright?2008RockwellAutomation,Inc.Allrightsreserved.40%Flow70%100%HeadControlbyValve/DamperEnergyusedEnergyusedBCAEnergyusedHowEnergyisSavedonPumpsandFansPump/Fanrunningat80%speedwithVFD,onlyconsumes50%ofenergy!Pump/Fanrunningat70%speedwithVFD,onlyconsumes34%ofenergy!PumpcurveSystemcurveControlbyaDriveCopyright?2007RockwellAutomation,Inc.Allrightsreserved.41離心風機/泵電機轉速與流量、壓力、耗能的關系Q1Q2=N1N2流量電機轉速H1H2=N1N2壓力2P1P2=N1N23耗能CentrifugalPump/Fan
