摘　　要：阐述了正弦与非正弦电路的无功电能表计量理论,介绍了电磁式和电子式无功电能表的各种无功电能计量方法,为系统了解和更有针对性地选择合适的理论方法提供了基础。As improvement of measurement technique and power system management, vat-hour meter techniques have made great progress. Different reactive energy measure theories are adopted for different circuits and many reactive energy measure methods are developed to meet different requirements of consumers. Measurement theory of vat-hour meter for sinusoidal and nonsinusoidal circuit are presented in this paper and the whole reactive energy measurement methods for electromagnetic or electronic var-hour meters are introduced so that a systematic knowledge and more reasonable selection on reactive energy measurement theories and methods can be achieved.
