The invention provides an intelligent power-rationing method and an intelligent electric meter. The intelligent power-rationing method comprises the steps that the intelligent electric meter receives a power-rationing instruction message from a control center; after receiving the power-rationing instruction message from the control center, the intelligent electric meter obtains target power-rationing power corresponding to the power-rationing instruction message; and the intelligent electric meter distributes a running state adjustment instruction to an intelligent electric appliance on a power utilization line to adjust a running state of the intelligent electric appliance on the power utilization line according to a power-rationing scheme preselected by a user so as to enable actual power-supply power to be smaller than the target power-rationing power, wherein the intelligent electric appliance comprises a receiving unit, and the receiving unit is used for receiving and executing the running state adjustment instruction from the intelligent electric meter. The invention provides a mode capable of replacing power failure to cope with the problem of power shortage in peak time of power utilization.
