Construction of testing system for energy efficiency measurement of high voltage motor and research of critical technology based on broadband sensing technology
Abstract: in order to meet accurate measurement for energy efficiency of high voltage three phase asynchronous motor, so make its function reach the requirement of energy efficiency measurement of high voltage and high efficiency motor, critical technical difficulties and revelant solutions for high voltage energy efficiency measurement are analyzed, and experimental platform based on loss analysis for high voltage motor energy efficiency measurement is constructed. Article clarifies the energy efficiency measurement platform based on broadband power measurement systematically, and overcomes the difficulties such as trouble in broadband signal acquisition, low stability and low accuracy in traditional way, so it adopts new technics such as broadband test and digital fiber optic transmission which promotes ability of signal acquisition in kinds of frequency, analysis, transmission, processing and electromagnetic interference resistance effectively, and reduces energy loss greatly. Platform realizes energy efficiency measurement for the high voltage motor of rated power below 2MW whose frequency ranges from 1Hz to 1kHz, through variable frequency power, optical fiber transmission, fully automated operation and human-computer interaction interface. Through the quantity traceability analysis of broadband power measurement system in the two table methods and relevant test which constructed in the paper, it verifies that measurement uncertainty of platform and technical characteristics meet the demand of national energy measurement demand, and opening and advancement with great flexibility is great.
