變頻電機發展過程

    變頻電機發展過程

    現在的電機變頻係統大都是采用的恒V/F控製係統
，這個變頻控製係統的特點是結構簡單、製zhi作zuo便bian宜yi。這zhe個ge係xi統tong被bei廣guang泛fan應ying用yong在zai風feng機ji等deng大da型xing的de並bing且qie對dui於yu變bian頻pin係xi統tong的de動dong態tai性xing能neng要yao求qiu不bu是shi很hen高gao的de地di方fang。這zhe個ge係xi統tong是shi一yi種zhong典dian型xing的de開kai環huan控kong製zhi係xi統tong
，這zhe個ge係xi統tong能neng夠gou滿man足zu大da多duo數shu電dian機ji的de平ping滑hua的de變bian速su要yao求qiu，但dan是shi對dui於yu動dong態tai和he靜jing態tai的de調tiao節jie性xing能neng都dou是shi有you限xian的de，不bu能neng應ying用yong在zai對dui動dong態tai和he靜jing態tai性xing能neng要yao求qiu比bi較jiao嚴yan格ge的de地di方fang。為wei了le實shi現xian動dong態tai和he靜jing態tai調tiao節jie的de高gao性xing能neng，我wo們men隻zhi能neng采cai用yong閉bi環huan控kong製zhi係xi統tong來lai實shi現xian。所suo以yi有you的de科ke研yan人ren員yuan提ti出chu了le控kong製zhi閉bi環huan轉zhuan差cha頻pin率lv的de電dian機ji調tiao速su方fang式shi

，這zhe種zhong調tiao速su方fang式shi能neng夠gou在zai靜jing態tai動dong態tai調tiao速su中zhong達da到dao很hen高gao的de性xing能neng，但dan是shi這zhe種zhong係xi統tong隻zhi能neng在zai轉zhuan速su比bi較jiao慢man的de電dian機ji中zhong得de到dao應ying用yong，應ying為wei在zai電dian機ji的de轉zhuan速su較jiao高gao的de時shi候hou
，這zhe種zhong係xi統tong不bu僅jin不bu會hui達da到dao節jie約yue電dian能neng的de目mu的de，還hai會hui使shi電dian機ji產chan生sheng極ji大da的de瞬shun態tai電dian流liu，使shi得de電dian機ji的de轉zhuan矩ju在zai瞬shun間jian發fa生sheng變bian化hua。所suo以yi說shuo為wei了le實shi現xian在zai較jiao高gao的de轉zhuan速su中zhong實shi現xian較jiao高gao的de動dong態tai和he靜jing態tai性xing能neng
，隻zhi有you先xian解jie決jue電dian機ji產chan生sheng瞬shun態tai電dian流liu的de問wen題ti，隻zhi有you將jiang這zhe個ge問wen題ti合he理li的de解jie決jue我wo們men才cai能neng更geng好hao的de發fa展zhan電dian機ji變bian頻pin節jie能neng控kong製zhi技ji術shu。
