The invention discloses an electric power wireless communication method applicable for distribution network automation. A base station can select different channel coding modes, rate matching modes and modulation modes according to error rate conditions of current channels, and send scheduling requests including the channel coding modes, the rate matching modes and the modulation modes in a down time slot. A terminal processes data requested by the base station by use of the channel coding modes, rate matching modes and modulation modes selected by the base station according to the scheduling requests, and send the data to the base station in an upper time slot. In this way, channel coding modes, rate matching modes and modulation modes, which are best for current channel error rate conditions, can be adopted, so use of the channels can be maximized and transmission efficiency of the data is increased.
