Based on the intelligent electric energy meter, the marketing remote cost control application system could realize the timely calculation, remote cost control and service of the prepaid customers. The cost control strategy of marketing remote cost control application system could realize the activities like reminder, reminder fees, power-cut and power-recovery of the electricity customers through matching the calculation result of users. In this paper, we mainly explore the large industrial customers, project the "switch" model based on the different energy consumption between production period and nonproduction period. When the load rate of the transformer greater than 30%, the customer is in production period, the early-warning charge is high; otherwise the early-warning charge is low. The cost control strategy based on the reasonable methods and means in the "switch" model can help us to achieve the aim of popularization and reasonable application of remote cost control.
