中文摘要:

对中国电科院研制建立的单相无功功率/电能计量标准装置做了阐述。基于电流比较仪式电桥,标准装置以交/直流转换标准、交流标准电阻和标准电容为基础,通过直接向直流电压标准溯源,确立一个准确的无功功率/电能标准值。装置的测量不确定度为30ppm。利用虚拟仪器技术,研究并设计无功计量装置的系统软件,从而实现无功表计的自动化校准和测试。

英文摘要:

This paper describes the new CEPRI single-phase reactive power calibration standard.Based on current-comparator Bridge,traceability is achieved by ac-dc transfer standard,reference resistor and reference capacitor.It allows calibrating active/reactive power and energy meters.The systematic uncertainty of the system is less than 30 parts per million(ppm) for reactive power calibration.Software of the calibration system is studied and designed by virtual apparatus programming language,thus performing automatic calibration of the reactive metering.
