Influence of harmonics on electric energy measurement
The influence of harmonics on electric energy measurement is discussed. The influence of linear and non - linear loads on electric energy measurement is studied. The irrationality in present electric energy measurement is pointed out by calculating the energy consumptions of linear and non -linear loads with harmonics. The simulative test is carried out based on the model established with RTDS(Real Time Digital Simulator) and the measuring process and measurement errors are analyzed. Test result shows that the consumer watt - hour is not in accordance with the energy consumed actually when the harmonic exists,so the current electric power measurements still have disadvantages and should be improved.
