Three-phase imbalance regulating system and method

Abstract

The invention discloses a three-phase imbalance regulating system, which comprises at least one charging pile, a distribution transformer and a control module, wherein the at least one charging pile is used for charging an electric vehicle; the distribution transformer is used for carrying out single-phase power supply on resident electricity load and the at least one charging pile; and the control module is used for obtaining electric energy from a phase line with low power consumption and compensating a phase line with high power consumption when detecting three-phase power imbalance of thedistribution transformer, thereby achieving three-phase power balance. The invention further discloses a three-phase imbalance regulating method. According to the three-phase imbalance regulating system and method, balance use of three-phase power of the distribution transformer can be ensured and the safety and reliability of power utilization are ensured.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a three-phase unbalance adjustment system and method. Background technique [0002] At present, my country's new energy vehicles are developing rapidly. Housing and construction committees all over the country have issued requirements for reserving parking spaces in new residential areas or installing charging piles in a certain proportion. Old residential areas also require charging pile installation and power distribution design in a certain proportion. . [0003] The power distribution in the community is three-phase power, but the actual practical new energy vehicles are mostly AC single-phase power to charge the car. In this context, there will be such a situation in each residential area. When the charging piles charge the new energy vehicles of the residents, due to the unbalanced use of the charging piles, the three-phase imbalance problem of the distribution trans...

AI Technical Summary

Problems solved by technology

In this context, there will be such a situation in each residential area. When the charging piles charge the new energy vehicles of the residents, due to the unbalanced use of the charging piles, the three-phase imbalance problem of the distribution transformer in the community will occur, resulting in the distribution of the community. One phase or two phases of the electric transformer are overloaded, which will cause the overheating trip protection of the transformer in the station area, and cause the power outage accident in the community

[0004] In addition, there is another situation. The distribution transformer of the original community did not consider the part of the charging power of new energy vehicles. When the charging piles charge new energy vehicles and the peak power consumption of users is superimposed, the transformer will be thermally protected due to overload. blackout
