The invention discloses a three-phase load balance control method based on a charging pile group, relates to the technical field of charging pile group control, solves the problem that the original three-phase control process is not accurate, and fully manifests the adaptability advantage by flexibly adjusting the current supply of each phase according to the current requirements at different moments. When the current demand at the next moment is the same as that at the previous moment, the current stable power supply state is maintained, unnecessary operation is reduced, and equipment loss is reduced; when the current demand is increased, a method of gradually increasing the current and synchronously coordinating each phase is ingeniously adopted, three-phase balance is orderly realized, each charging pile can obtain stable and sufficient electric power, the overall charging efficiency is improved, the waiting time of a vehicle due to insufficient electric power is shortened, and in the scene that the current demand is reduced, the current is controlled to be gradually reduced by reverse thinking; three-phase balance is ensured in the whole process, and equipment impact or power grid fluctuation caused by sudden reduction of current is avoided.
本发明公开了基于充电桩桩群三相负载平衡控制方法,本发明涉及充电桩桩群控制技术领域,解决了原始的三相控制进程并不精准的问题,本发明通过根据不同时刻电流需求灵活调整各相电流供应,充分彰显其适应性优势;当后一时刻电流需求与前一时刻相同,维持当前稳定供电状态,减少不必要操作,降低设备损耗;面对电流需求上升时,巧妙采用逐步提升电流、同步协调各相的方法,有条不紊地实现三相平衡,保证每个充电桩都能获得稳定、充足电力,提升整体充电效率,减少车辆因电力不足等待时间,电流需求下降场景下,逆向思维控制电流逐步下降,全程确保三相平衡,避免因电流骤减造成设备冲击或电网波动。
