TÓM TẮT
Nowadays power quality has become a very important issue in the power distribution network. With anincrease in energy demand, the requirements for power quality are also much higher than before. One of the power quality issues in the distribution network is harmonic. The influence of harmonic on the power network includes energy losses, current distortion and voltage waveforms on the distribution network. Besides, harmonic affects relay protection and other sensitive electrical equipment of the distribution network. In the paper, the harmonic measurement data on some industrial plants in Central Vietnam’s provinces has been provided. Based on this data, the parameters have been calculated, using theMatlab/Simulink software. A passive filter has been suggested for improving the power quality of the distribution network.
