[0033] Through steps one to three, the above method can effectively reduce the resource investment required for simultaneously monitoring multiple power links, which helps to control the operating costs of the new power system. Through step four, the power links with potential hidden dangers can be quickly identified, thereby improving the monitoring efficiency of the new power system.

[0034] Example 2

[0035] Reference Figures 2 to 3 The comprehensive information monitoring system of the new power system includes a comprehensive information monitoring module, a power link marking module, and a monitoring priority locking module.

[0036] Comprehensive information monitoring module: obtain the monitoring preset values ​​of each power link in the new power system (the new power system is a complex and comprehensive system, which covers multiple power links. The power links are interrelated and interact with each other to form a new power system to achieve efficient, clean, safe and sustainable development of energy. The power links include but are not limited to the power generation side, transmission side, distribution side, power consumption side, and energy storage side), and sort the power links in descending order according to the value of the monitoring preset value. Every t time, conduct a comprehensive analysis of each power link in turn according to the sorting of the power links.

[0037] Power link marking module: after comprehensive analysis of each power link, a comprehensive analysis log of the power link is generated. The comprehensive analysis log includes the power link name (i.e. the name of the power link), the comprehensive information value, and the log generation time. The comprehensive information value of the comprehensive analysis log is obtained, and the comprehensive information threshold of the power link is obtained simultaneously (each power link corresponds to an independent comprehensive information threshold, and the comprehensive information thresholds of different power links are not necessarily the same). When the comprehensive information value is greater than or equal to the comprehensive information threshold, the power link is marked as a hidden danger power link. When the comprehensive information value is less than the comprehensive information threshold, the power link is not marked, and the next power link is comprehensively analyzed synchronously according to the order of the power links.

[0038] By setting up a comprehensive information monitoring module and a power link marking module, the monitoring order and priority of different power links in the new power system can be reasonably arranged, which not only ensures that each power link is monitored independently, but also helps to conduct in-depth and detailed analysis of each power link, facilitates the discovery of unique problems in each power link, and can effectively reduce the resource investment required for monitoring multiple power links at the same time, which helps to control the operating costs of the new power system.

[0039] The monitoring preset value of the power link is obtained in the following way: obtain all comprehensive analysis logs of the new power system before the current time of the system, obtain the power link name of the comprehensive analysis log, mark the comprehensive analysis log with the same power link name as the same-link comprehensive analysis log, obtain the comprehensive information value of the same-link comprehensive analysis log, sum and average the comprehensive information values ​​of all the same-link comprehensive analysis logs, and obtain the comprehensive information mean FCY, obtain the log generation time of the same-link comprehensive analysis log, sort all the same-link comprehensive analysis logs in the order of log generation time, sum and average the two adjacent comprehensive information values ​​after sorting, and obtain the comprehensive neighbor mean, set the comprehensive neighbor mean threshold (the system sets the threshold and can be adjusted according to actual needs), when the comprehensive neighbor mean is greater than or equal to the comprehensive neighbor mean threshold, increase the number of comprehensive neighbor shadows by one, when the comprehensive neighbor mean is less than the comprehensive neighbor mean threshold, do not process it, sum the number of comprehensive neighbor shadows, and obtain the total number of comprehensive neighbor shadows HMg, using the formula The monitoring preset value Juc of the power link is obtained, where P1 is the comprehensive information mean coefficient, P2 is the comprehensive neighboring shadow total number coefficient, the value of P1 is 0.82, and the value of P2 is 0.74.

[0040] The comprehensive information value of the comprehensive analysis log is obtained in the following way: obtain the power link name of the comprehensive analysis log, obtain various power information of the power link within the time length t (each power link contains various power information, such as the transmission side contains line operation status information, transmission equipment status information, transmission environment impact information, etc., such as the power consumption side contains power load information, power quality information, power safety information, etc.), obtain the power information impact model of various power information (each power information corresponds to an independent power information impact model), input each power information into the corresponding power information impact model, obtain the power information impact value of various power information, obtain the power information impact limit of various power information (each power information corresponds to an independent power information impact limit, that is, the system sets the threshold and adjusts it according to actual needs), compare the power information impact value of the same power information with the power information impact limit, and when the power information When the impact value is greater than or equal to the power information impact limit, the power information is marked as operation hidden danger information. When the power information impact value is less than the power information impact limit, the power information is marked as normal operation information. The total number of operation hidden danger information of the power link is marked as EY, and the total number of normal operation information of the power link is marked as XK. The power information impact value of all operation hidden danger information and the power information impact limit are calculated by difference to obtain the hidden danger impact prominent value SRz. The hidden danger impact prominent value coefficient is set to AGg, g = 1, 2, 3, ..., g; AG1 < AG2 < AG3 < ... < AGg. Each of the above hidden danger impact prominent value coefficients corresponds to a different range of hidden danger impact prominent values, including [0, SR1], (SR1, SR2], ..., (SRZ-1, SRZ]. When the hidden danger impact prominent value SRz∈[0, SR1], the hidden danger impact prominent value coefficient is AG1. Using the formula The comprehensive information value Zxz of the power link is obtained, where s1 is the coefficient of the number of operation hidden danger information, s2 is the coefficient of the number of normal operation information, z=1, 2,..., Z, Z is the total number of operation hidden danger information, the value of s1 is 1.83, and the value of s2 is 1.59.

[0041] Different power information corresponds to different power information impact models. Different electronic information impact models are constructed in the same way, but the training data of the model needs to be replaced. The following takes the line operation status information as an example to disclose the construction method of the power information impact model: collect n groups of line operation status information, each group of line operation status information contains multiple information related to the line operation status, and the information related to the line operation status includes but is not limited to line temperature, line active power, line reactive power, and line voltage. Build a deep learning model, use n groups of line operation status information as training data for the deep learning model, assign a power information impact value to each training data, divide multiple training data into training sets and validation sets at a ratio of 1:2, and obtain the power information impact model through training the training set and validation set. Among them, the value range of the power information impact value is (1~2), the larger the value of the power information impact value, the higher the line operation status will cause the operation risk of the new power system to increase, and the smaller the value of the power information impact value, the lower the line operation status will cause the operation risk of the new power system to decrease.

[0042] Monitoring priority locking: When a hidden danger power link appears, the remaining power links ranked after the hidden danger power link will be marked as power links for investigation, and the comprehensive monitoring value of the hidden danger power link and the comprehensive monitoring value of the power link for investigation will be obtained, and then the locking priority value of the power link for investigation will be obtained, and all the power links for investigation will be sorted in order from small to large according to the locking priority value, and the power links for investigation will be comprehensively analyzed in the sorting order.

[0043] By setting the monitoring priority lock, when a hidden danger is found in a certain power link, the monitoring order of the power link can be flexibly adjusted according to the power link with the hidden danger, which helps to quickly lock the power link with potential hidden dangers and improve the monitoring efficiency of the new power system.

[0044] The comprehensive monitoring value of the link is obtained in the following way: obtain m consecutive comprehensive analysis logs of the same power link before the current time of the system, obtain the comprehensive information value of the comprehensive analysis log, set the high value of the comprehensive information and the low value of the comprehensive information (the high value of the comprehensive information is greater than the low value of the comprehensive information, and the high value of the comprehensive information and the low value of the comprehensive information are the thresholds set by the system, which can be adjusted according to actual needs); when the comprehensive information value of the comprehensive analysis log is greater than or equal to the high value of the comprehensive information, mark the type of the comprehensive analysis log as a high hidden danger type; when the comprehensive information value of the comprehensive analysis log is less than or equal to the low value of the comprehensive information, mark the type of the comprehensive analysis log as a low hidden danger type; when the comprehensive information value of the comprehensive analysis log is between the high value of the comprehensive information and the low value of the comprehensive information, mark the type of the comprehensive analysis log as a low hidden danger type. The type of the log is marked as the medium hidden danger type. All comprehensive analysis logs are sorted in the order of log generation time. The types of two adjacent comprehensive analysis logs after sorting are compared. When the types of two adjacent comprehensive analysis logs are the same, no processing is performed. When the types of two adjacent comprehensive analysis logs are different, the number of hidden danger changes is increased by one. The number of hidden danger changes is summed to obtain the total number of hidden danger changes ddg. All comprehensive analysis logs of high hidden danger types are sorted in the order of log generation time. The log generation time of the two adjacent comprehensive analysis logs after sorting is calculated by time difference to obtain the high hidden danger log interval. All high hidden danger log intervals are summed and averaged to obtain the average high hidden danger log interval RSW. The formula is used The comprehensive monitoring value AED of the power link is obtained, where k1 is the total number of hidden danger changes coefficient, k2 is the average high hidden danger log interval coefficient, the value of k1 is 0.63, and the value of k2 is 0.57.

[0045] The locking priority value of the power link under investigation is obtained by the following method: the difference between the comprehensive monitoring value of the hidden danger power link and the comprehensive monitoring value of the power link under investigation is calculated, and then the locking priority value of the power link under investigation is obtained.
