CONSUMER ELECTRIC ENERGY MEASUREMENT IN CONSIDERATION OF HARMONIC POLLUTION
Tong Xiangqian, Xue Junyi (Xi'an Jiaotong University, Xi'an 710049, China)
Under power market, it is necessary for utilities and power consumers to consider the effects of both consumer harmonics on the network and network background harmonics on consumers in electric metering systems. By discussing the characteristics of harmonic energy at the point of common coupling (PCC), an uniform watt hour metering method that all consumers pay for their fundamental energy at PCC without regard to the existence of harmonics in the network or the consumer is presented. Theoretic analysis and field measurement results indicate that the consumer watt hour should not be the energy consumed actually but the fundamental energy in consideration of harmonic energy loss.
