The power supply current can be subjected to overload acquisition subsection control and ordered charging. Operating current of a power supply transformer is collected and divided into a plurality of time periods, a first time period is a time period which does not reach rated current, a charging pile can perform direct charging or reserved charging and belongs to a low-load disordered charging time period, and when peak power consumption reaches the rated current or exceeds the rated current full load, a second time period is started. Power supply current collection begins to uniformly dispatch all automobile charging piles in a community for ordered charging, the time period belongs to a full-load ordered charging period, the running current of a power supply transformer is controlled within rated current, and in a set delay time, if an electricity load still cannot be balanced within two hours, a third period is automatically switched to, and the time period is switched to a fourth period; in the third period, the delay time is set not to exceed two hours according to the rule that the power supply transformer is allowed to be overloaded for 20% two hours, that is, the power supply capacity of the community is increased by 20% within two hours, the third period belongs to an overload ordered charging period, and the peak power consumption of the community can be quickly relieved through overload ordered charging.
本发明供电电流可超载采集分段控制与有序充电。我们把供电变压器运行电流采集分多个时段,第一时段是没有达到额定电流时段,充电桩可以直充或预约充电,属低负荷无序充电时段,当高峰用电达到额定电流或超过额定电流满载时进入第二时段,供电电流采集开始对小区内所有汽车充电桩统一调度进行有序充电,属满载有序充电时段,将供电变压器运行电流控制在额定电流内,在设定的延缓时间内如两个小时内用电负载仍然不能平衡时自动转入第三时段,第三时段是根据供电变压器允许超载20%2小时的规定,设定延缓时间不得超过两小时,相当于小区供电容量在两小时内增加了20%,属超载有序充电时段,超载有序充电应该很快使小区高峰用电得到缓解。
