With the growth of population, the progress of industrialization and the acceleration of urbanization, the demand for electricity is increasing. Conventional power systems face challenges such as insufficient power transmission capability and unstable power supply. To meet the growing demand for electricity, it is often necessary to construct new transmission lines. However, newly built transmission lines face a number of difficulties including land acquisition, environmental protection, investment costs, etc. In addition, the time period of newly-built transmission line is longer, can't in time satisfy urgent electric power demand.
To address these problems, researchers and power companies have begun to explore methods of dynamic compatibilization using existing transmission lines. The dynamic capacity-increasing technology aims at meeting the increase of power requirements, prolonging the service life of the line and reducing the requirements of newly-built power transmission lines by improving the transmission capacity of the existing power transmission lines. The dynamic capacity-increasing monitoring terminal of the power transmission line monitors the operation parameters and the environmental conditions of the power transmission line, and evaluates the dynamic safety current-carrying capacity of the power transmission line in real time so as to furthest excavate the power transmission potential of the power transmission line and improve the transmission capacity of the power transmission line.
Due to engineering cost, it is impossible to install a dynamic capacity-increasing monitoring terminal on each section of transmission wire, and only a representative capacity-increasing bottleneck point can be selected to install the monitoring terminal. Therefore, the dynamic capacity-increasing monitoring terminal is distributed on the power transmission line, and the dynamic capacity-increasing monitoring terminal is arranged in the area with the highest risk during dynamic capacity-increasing operation, namely the area with the highest wire temperature and the largest wire sag, so that the wire temperature value and the sag value of the risk position can be monitored in real time, the wire temperature exceeding and the sag out-of-limit are prevented, and the safe operation of the line is endangered.
In addition, the dynamic capacity-increasing monitoring terminal arranged on the transmission line generally monitors the corresponding section line according to a preset fixed monitoring frequency, so that the differential monitoring requirements of the lines in different environments cannot be met, and further the monitoring resource waste of the low-risk section line and the monitoring frequency deficiency of the high-risk section line are caused.
In order to solve the above technical problems, in the method for managing a power transmission line dynamic capacity-increasing monitoring terminal according to the present embodiment, each dynamic capacity-increasing monitoring terminal in the set of dynamic capacity-increasing monitoring terminals respectively obtains monitoring data of a section to be monitored corresponding to a line to be monitored, so as to send the monitoring data to a monitoring management cloud platform, and then the monitoring management cloud platform determines a first monitoring frequency according to first monitoring data corresponding to the first dynamic capacity-increasing monitoring terminal and a preset monitoring frequency evaluation model, and sends the first monitoring frequency to the first dynamic capacity-increasing monitoring terminal, so that the first dynamic capacity-increasing monitoring terminal monitors the first section to be monitored according to the first monitoring frequency, and therefore, the monitoring frequency of the dynamic capacity-increasing monitoring terminal is dynamically adjusted according to actual monitoring data, monitoring resource waste of the line in the low risk section is effectively avoided, and monitoring reliability of the line in the high risk section is effectively ensured.

The dynamic capacity-increasing monitoring management system can comprise a monitoring management cloud platform and a dynamic capacity-increasing monitoring terminal set, wherein each dynamic capacity-increasing monitoring terminal in the dynamic capacity-increasing monitoring terminal set is respectively in communication connection with the monitoring management cloud platform. Optionally, the dynamic capacity-increasing monitoring terminal is an intelligent device in the electric power system, and is mainly used for monitoring the running state and the environmental condition of the high-voltage transmission line in real time, so as to evaluate and determine the maximum allowable current-carrying capacity of the line on the premise of ensuring the safety, and realize the dynamic capacity increase of the transmission line. Such terminals typically integrate a variety of sensor technologies, data communication technologies, and data analysis algorithms, the functions of which include achieving physical quantity monitoring, image monitoring, and wireless communication. The physical quantity monitoring can be realized by measuring the temperature of the lead wire in real time through a temperature sensor arranged on the lead wire, collecting weather information such as wind speed, wind direction, humidity, sunlight intensity and the like, and monitoring the current passing through the power transmission line. For image monitoring, a high-definition camera is used for shooting on-site photos or videos and used for observing the condition of wire waving and the change of the surrounding environment of a circuit. And then, the collected data are transmitted to a monitoring management cloud platform in real time by utilizing wireless communication technologies such as GPRS/3G/4G/5G and the like. Through the dynamic capacity-increasing monitoring terminal, the electric power department can manage the power transmission line more finely, improve the transmission efficiency of the power grid, reduce the potential safety hazard caused by overload, and utilize the existing line resources to the maximum extent on the premise of not affecting the safety.
In this step, each dynamic capacity-increasing monitoring terminal in the dynamic capacity-increasing monitoring terminal set respectively obtains monitoring data of a section to be monitored corresponding to a line to be monitored, so as to send the monitoring data to the monitoring management cloud platform, wherein the line to be monitored comprises a plurality of sections to be monitored.
S102, the monitoring management cloud platform determines a first monitoring frequency according to first monitoring data corresponding to the first dynamic capacity-increasing monitoring terminal and a preset monitoring frequency evaluation model.
In this step, the monitoring management cloud platform determines the first monitoring frequency according to the first monitoring data corresponding to the first dynamic capacity-increasing monitoring terminal and the preset monitoring frequency evaluation model, where the first dynamic capacity-increasing monitoring terminal is any dynamic capacity-increasing monitoring terminal in the dynamic capacity-increasing monitoring terminal set.
Specifically, the monitoring management cloud platform may utilize equation 1 and according to the first monitoring temperatureFirst monitoring sag/>Determining the first monitoring frequency/>Wherein, formula 1 is:

Specifically, the monitoring management cloud platform sends the first monitoring frequency to the first dynamic capacity-increasing monitoring terminal, so that the first dynamic capacity-increasing monitoring terminal monitors the first section to be monitored according to the first monitoring frequency.
In this embodiment, each dynamic capacity-increasing monitoring terminal in the dynamic capacity-increasing monitoring terminal set is used for respectively acquiring monitoring data of a section to be monitored corresponding to a line to be monitored, so as to send the monitoring data to the monitoring management cloud platform, then the monitoring management cloud platform determines a first monitoring frequency according to the first monitoring data corresponding to the first dynamic capacity-increasing monitoring terminal and a preset monitoring frequency evaluation model, and sends the first monitoring frequency to the first dynamic capacity-increasing monitoring terminal, so that the first dynamic capacity-increasing monitoring terminal monitors the first section to be monitored according to the first monitoring frequency, and therefore dynamic adjustment of the monitoring frequency of the dynamic capacity-increasing monitoring terminal according to actual monitoring data is achieved, monitoring resource waste of the line in the low-risk section is effectively avoided, and meanwhile monitoring reliability of the line in the high-risk section is effectively guaranteed.

Therefore, each dynamic capacity-increasing monitoring terminal in the first subsequence of the dynamic capacity-increasing monitoring terminal responds to the suspension monitoring instruction, data monitoring of the corresponding section to be monitored is suspended, and monitoring can be suspended for part of the dynamic capacity-increasing monitoring terminals in the safety section with the monitoring frequency continuously lower than the preset monitoring frequency threshold, so that monitoring resources are effectively saved. It should be noted that after the dynamic capacity-increasing monitoring terminal in the second sub-sequence monitors the abnormal data, the dynamic capacity-increasing monitoring terminal in the first sub-sequence is woken up again to monitor again, so as to improve the monitoring reliability. Therefore, by the dynamic monitoring adjustment mode, the waste of monitoring resources of the continuous low-risk section line is effectively avoided, and meanwhile, the reliability of monitoring the high-risk section line is effectively ensured.
In addition, after each dynamic capacity-increasing monitoring terminal in the first subsequence of the dynamic capacity-increasing monitoring terminal responds to a suspension monitoring instruction and suspends data monitoring of the corresponding section to be monitored, the dynamic capacity-increasing monitoring terminal in the first subsequence of the dynamic capacity-increasing monitoring terminal sends a withdrawal monitoring request to the monitoring management cloud platform after the first time length of the dynamic capacity-increasing monitoring terminal in the first subsequence of the dynamic capacity-increasing monitoring terminal suspending data monitoring of the corresponding section to be monitored exceeds a preset time length threshold. And the monitoring management cloud platform determines that the monitoring data of each section to be monitored does not have abnormality in the first duration, and sends an exit monitoring confirmation instruction to the dynamic capacity-increasing monitoring terminal in the first subsequence of the dynamic capacity-increasing monitoring terminal so as to enable the exit monitoring indicator lamp on the dynamic capacity-increasing monitoring terminal in the first subsequence of the dynamic capacity-increasing monitoring terminal to flash. The monitoring management cloud platform sends a dynamic capacity-increasing monitoring terminal recovery instruction to the monitoring management terminal, the dynamic capacity-increasing monitoring terminal recovery instruction comprises position information of the dynamic capacity-increasing monitoring terminal in a first subsequence of the dynamic capacity-increasing monitoring terminal, the dynamic capacity-increasing monitoring management system comprises the monitoring management terminal, and the monitoring management terminal is in communication connection with the monitoring management cloud platform. Therefore, after judging according to the actual monitoring data, the part of the dynamic capacity-increasing monitoring terminals are recovered in a targeted mode, so that the monitoring of the dynamic capacity-increasing monitoring terminals can be guaranteed to meet the actual working condition environment, the number of the dynamic capacity-increasing monitoring terminals can be reduced as much as possible, the operation cost is effectively reduced, and the multiplexing rate of equipment is improved.
Further, after the exit monitoring confirmation instruction is sent to the dynamic capacity-increasing monitoring terminal in the first subsequence of the dynamic capacity-increasing monitoring terminal, the monitoring management cloud platform sends a monitoring frequency increasing instruction to the dynamic capacity-increasing monitoring terminal in the second subsequence of the dynamic capacity-increasing monitoring terminal, so that the frequency of data monitoring is increased by the dynamic capacity-increasing monitoring terminal in the second subsequence of the dynamic capacity-increasing monitoring terminal, the monitoring frequency of the section is increased under the condition that the number of the dynamic capacity-increasing monitoring terminals of the section is reduced, and after a period of time, if abnormal data does not occur, the monitoring frequency can be restored to the original monitoring frequency.
At present, for the installation and distribution of dynamic capacity-increasing monitoring terminals on a line, because of the lack of an effective and reasonable guiding method, for an actual transmission line, an evenly distributed installation and distribution mode is directly adopted, namely, one set of monitoring terminals is installed at intervals of a fixed distance (such as 10 km). This even distribution has to be done in a way that is practically without any rationality. The installation distribution points of the dynamic capacity-increasing monitoring terminal are combined with capacity-increasing operation risks of all the wire sections of the power transmission line to determine reasonable installation positions, and only then the operation safety of the power transmission line during the dynamic capacity-increasing period can be fully ensured.
