The design of on - line three - phase input and output variable frequency uninterruptable power supply 在線式三進(jìn)三出交流變頻不間斷電源的設(shè)計(jì)
Aiming at the impact of electric network fluctuation on frequency diverter , it provides countermeasures in aspects of expanding electric network capacity , technical reformation , electric network filtering , applying on - line tap changer and uninterruptable power supply , and modifying frequency inverter parameter setup 針對(duì)電網(wǎng)波動(dòng)對(duì)變頻器運(yùn)行造成的影響,從電網(wǎng)擴(kuò)容與技術(shù)改造、電網(wǎng)濾波、采用有載調(diào)壓變壓器和不間斷電源、修改變頻器參數(shù)設(shè)置等方面提出了相應(yīng)的措施。
At present , fes technology has been successfully applied in many fields such as uninterruptable power supply ( ups ) systems , electric power systems , hybrid electric vehicles , etc . researches indicate that in energy sources and attitude control system of satellites , by fess both energy storage and attitude control can be accomplished . it would be remarkable to improve global performance of satellites , so aeronautics & astronautics departments attach great importance to fess 研究表明,在衛(wèi)星能源和姿態(tài)控制系統(tǒng)中,利用飛輪儲(chǔ)能系統(tǒng)可以同時(shí)完成能量?jī)?chǔ)存和姿態(tài)控制兩方面的功能,這對(duì)于提高衛(wèi)星的總體性能有著顯著的意義,因而得到航空航天部門的重視,并成為該研究方向的前沿課題,但目前尚未進(jìn)入實(shí)用階段。
