[0002] Communication equipment protocols are a set of rules for data exchange and communication within a substation and between the substation and external networks. They define key elements such as data format, transmission rate, synchronization method, error detection and correction mechanisms, ensuring the accuracy and integrity of information during transmission.

[0150] Step S08: Communication Equipment Operation Status Assessment: The communication equipment protocol verification coefficient used to obtain the substation communication operation status is compared with the communication equipment protocol standard verification coefficient and processed.

[0151] In this embodiment, it should be specifically explained that the present invention collects substation communication data for each monitoring sub-period of the substation communication operation status through communication equipment. The communication equipment performance monitoring index for each monitoring sub-period of the substation communication operation status is calculated based on the communication equipment performance data acquisition unit, and the substation operation efficiency monitoring index for each monitoring sub-period of the substation communication operation status is calculated based on the substation operation efficiency data acquisition unit. Further analysis yields the communication equipment protocol verification coefficient, which is compared with the communication equipment protocol standard verification coefficient. If the communication equipment protocol verification coefficient for the substation communication operation status is less than the communication equipment protocol standard verification coefficient, it indicates that the substation communication equipment does not meet the reliability standard. The substation communication equipment that does not meet the reliability standard should be located, and management personnel should be notified for inspection. Conversely, if the coefficient is greater than the coefficient, it indicates that the substation communication equipment meets the reliability standard. By utilizing a custom data acquisition frequency period division, subtle changes in the substation communication status can be captured, improving the accuracy of data acquisition. By monitoring and analyzing the communication operation status data of the substation communication equipment, it is beneficial to promptly address potential problems and hidden dangers, ensuring the reliability and stability of the substation communication equipment and improving the overall operating efficiency and safety of the substation.

[0152] This invention calculates the first substation communication operation status by using the historical communication equipment performance monitoring index for each monitoring sub-period. The communication equipment fault judgment index of the substation communication operation status in each time period is used to determine the time period in which the communication network status is abnormal. The substation operation efficiency monitoring index of each abnormal monitoring sub-period of the substation communication operation status is used to calculate the [missing information - likely a specific calculation method or index]. The communication equipment fault repair and diagnosis index is calculated for each time period of the substation's communication operation status. The repair effect of communication faults is evaluated based on the calculation results of the communication equipment fault repair and diagnosis index. By calculating the communication equipment fault judgment index, the time periods in which the communication network status is abnormal can be identified. After identifying the abnormal time periods, managers can carry out more targeted inspection and maintenance work, avoiding blind investigation and waste of resources, and improving the management efficiency of substation communication equipment. Furthermore, through the scientific evaluation of the fault repair effect, a closed-loop management from fault discovery to repair effect evaluation is realized, which greatly improves operation and maintenance efficiency and achieves refined, intelligent and efficient fault management.

Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
