[0025] The utility model provides a data analysis device for electricity sales management, please refer to Figure 1-4 A smart distribution network data management and analysis device includes a terminal acquisition unit, a data transmission unit 3 and a background processing unit. The terminal acquisition unit includes a digital meter 1 and a data concentrator 2.

[0026] The following is a description of the process using an analysis cycle: Taking a sampling cycle of 12 hours as an example, the sampling data includes the power load data collected in 12 hours, including power supply E1, maximum load power consumption E2, minimum load power consumption E3 and line loss power P0. Assuming that the power supply E1 is a stable supply during the sampling cycle, the average load parameter and the maximum and minimum values ​​of the average load limit value can be calculated based on the power parameter. The ratio of cycle power consumption to time is the average load. The average load parameters within 12 hours are: average power supply load P1 = E1 / 12, power consumption load P at maximum load 2=E2 / 12, power load at minimum load P3=E3 / 12, then calculate the maximum and minimum values ​​respectively to determine the adjustment range of the background processing unit of the power grid, then the maximum value PMAX=K1*(P1-P3+P0), the minimum value PMIN=K2*(P1-P2), where K1 and K2 are coefficients related to the rated carrying capacity of the power supply system; after calculating various relevant data, the data to be uploaded adopts TCP / IP protocol and is transmitted to the background processing unit through the optical fiber Ethernet network, and the subsequent data sending process also uses this method to realize the interconnection and exchange of data.

[0027] After the analysis process is completed, the processing process begins. After the background processing unit receives the load parameter data, it uses the data as a parameter variable to input into the overall operation requirements of the power grid. According to the different periods of operation of the overall power grid and the different load amounts, the regulated load value PC of each distribution network is obtained and periodically sent down through the optical fiber network. The sending period can be set to 2 hours. The system calculates the total load deviation value P based on the regulated load value. The total load deviation value P is the difference between the maximum power supply load P4, the extreme load P5, and the regulated load PC, that is, P=P4-P5+PC. The load correction value F*P is calculated based on the load cost function F. Under the premise of satisfying the load deviation correction, the optimal regulation correction plan is determined based on the principle of optimal cost ratio. The early warning module mainly realizes alarm processing. If the measured data exceeds the warning value, the on-duty personnel and the area manager can be prompted by sound, text, electronic map, or mobile phone alarm.
