Description
Technical Field

[0002] The main function of power equipment communication transmission encryption is to protect data security, prevent information leakage and improve system security. Through encryption technology, power equipment communication transmission can prevent sensitive information from being intercepted during transmission. The real-time data transmitted in the power system includes remote control, remote adjustment and setting value information of protection devices, etc. These data are related to the equipment status and directly affect the safe operation of the power grid. Encrypting the data during the transmission process through wireless communication technology can effectively prevent this information from being stolen. For example, after using the area identification instrument to collect the phase and attribute information of the user's electric energy meter, the collected data needs to be transmitted to the data monitoring center. Encrypting these data during the transmission process can effectively prevent the user's electric energy meter information from being stolen; However, in the process of data transmission of power equipment, while ensuring data security, it is also necessary to ensure data transmission efficiency. In the use of the power equipment such as the substation identification instrument, the uncertainty of the identification distance has always been a hidden danger problem. Due to the different line impedances caused by different user loads in different time periods, coupled with the uncertainty of the identification distance, it is easy for the substation identification instrument to sometimes receive the carrier signal during use, but sometimes not. As a result, the substation identification instrument cannot accurately and efficiently collect user electricity meter information to transmit the collected data to the data monitoring center, affecting the data transmission efficiency of the power equipment.

The user load of the current planned period is predicted through an exponential smoothing algorithm, which is conducive to accurately estimating the interference data that will be encountered when using the area identification instrument to collect information in the current planned period; After predicting the user load in the current planned period, obtain the identification distance at which the substation identification instrument can receive the carrier signal when it was in the corresponding environment in the past, that is, when the user load is the predicted load, and further analyze the effective identification distance under the interference of the corresponding user load. Considering that setting an appropriate signal transmission frequency can effectively improve the identification problem of the substation identification instrument, when the signal transmission frequency is set appropriately, the substation identification instrument can identify the electric energy meter information within the effective identification distance. By establishing a signal transmission frequency model, the effective identification distance obtained under the interference of the corresponding user load is input into the signal transmission frequency model to predict the optimal signal transmission frequency of the substation identification instrument in the current planned period. The substation identification instrument is used to collect the electric energy meter information within the effective identification distance according to the predicted signal transmission frequency, which is conducive to improving the information collection efficiency of the substation identification instrument, and then the collected data is transmitted to the data monitoring center, which further improves the data transmission efficiency of the substation identification instrument.
