Abstract

In order to study the influence of unbalanced three-phase load on distribution transformer's outlet voltage, the ATP-EMTP simulation model has been built. Distribution transformer's outlet voltage under different load parameters has been researched. The simulation results show that active and reactive power have influence on distribution transformer's outlet voltage simultaneously. The unbalanced three-phase load will cause the unbalance of distribution transformer's outlet three-phase voltage. The simulation results agree well with the measured results. It's actually not the case that the heavier the load, the lower the phase voltage while the lighter the load, the higher the phase voltage. When the three-phase load is unbalanced, there are 6 kinds of relationship between the distribution transformer's outlet three phase voltage.
