Research on Harmonics and Voltage Sags in Distribution Networks
This article studies voltage sags and total harmonic distortion(THD)in distribution networks.The experimental power grid was modeled by power sources,lines,and power impedance.The electrical load of the network is an electronic load,which is a rectifier bridge,and its output terminals are connected to capacitor banks and linear resistors.The power quality of the distribution network by changing the load impedance,capacitor banks,and number of loads in the distribution network were analyzed.The voltage sags and THD in distribution networks were studied using PSCAD and MATLAB software.
