Project background:
Electric vehicle battery swap stations use a large number of switching power supplies during the charging process to rectify AC power into DC power to charge the battery. Therefore, a large number of switching power supplies are used to charge the battery during the charging process. A large number of third harmonics are generated, and the third harmonics are superimposed on the neutral line, resulting in problems such as excessive neutral current. For conventional three-phase approximately balanced loads, the normal current of the neutral line is generally less than 30% of the phase current. No matter how the intelligent charging system configures the load distribution, the change in charging load will still cause instantaneous three-phase imbalance. The application of these nonlinear loads poses a serious safety hazard to the safe and stable operation of the power supply and distribution system. A large number of harmonics are injected into the system. Once a power failure occurs, it will cause serious economic losses at the least, and cause public events at the worst, resulting in serious consequences.
CoEpower Harmonic solution:
The closer the AHF is installed to the harmonic source, the more obvious the reduction in neutral current. Therefore, we can analyze the load harmonic source data and perform harmonic control for different harmonic pollution situations based on the power distribution of the charging station.
