Abstract

The invention, which belongs to the field of power distribution, provides an adjustment ad treatment device for simulating grid high-power three-phase unbalance. The device comprises a switch device,a three-phase transformer, a three-phase unbalance host, an extension, and a user load. After the switch device is connected, the three-phase unbalance host detects the voltage and current of the three-phase power supply to calculate the power; and the grid three-phase unbalance is simulated by adjusting the load device. Therefore, a problem that the user is not easy to understand the three-phaseunbalance and the related studies can not be performed conveniently because of lots of energy consumption caused by the experiment is solved.

Description

technical field [0001] The invention belongs to the technical field of power distribution, and in particular relates to a high-power three-phase unbalance adjustment and control device for a simulated power grid. Background technique [0002] Because the three-phase power supply and single-phase power supply of electrical equipment are used in combination, the three-phase unbalance objectively exists in different loads and different power consumption times, and it is difficult to grasp the law of the power load and cannot be predicted in advance. To study the three-phase unbalance needs to use large-scale in the experiment. Power equipment simulation, high-power equipment has high cost and high energy consumption, and when the three-phase unbalance is high, it will cause great harm to the equipment, resulting in short life of the equipment, and the entire experiment cost is extremely high. Contents of the invention [0003] The purpose of the present invention is to provid...
