State Grid Putian Power Supply Company: Increased the "Smart Engine" for the improvement of the quality and efficiency of the operation inspection

On September 26, the Putian Power Supply Company of State Grid launched an analysis of the risk management control analysis of 220 kV Hanjiang changes through the operation risk board of the Intelligent Production Management Center, ensuring the safe and orderly development of on -site operations.

In April 2022, Putian Power Supply Company officially launched the Intelligent Production Management Center to strengthen the quality control of equipment and ensure the reliable supply of power as the main goal. Carry out major businesses such as the entire element of production information, the entire process of equipment health, the entire process of production operations, and the full process of the whole process of key tasks. Promote the transformation of equipment management from "offline to online, extensive to lean, passive to active", to the company for the company The improvement of the penetration and lean management level of operational inspection management provides a strong "wisdom engine".

Digital wisdom and capability, build a "peak summer" firewall

On August 23, the Putian Power Supply Company Intelligent Production Management Center through comprehensive analysis equipment thermal temperature and power outage risk to determine the Licheng transformed 110 kV Lidong Road Ⅱ Ⅱ isolation switch B phase and the line -connected line of the bybilitt connection. Power treatment, based on dynamic tracking abnormal information, carry out comprehensive diagnosis and analysis of equipment, and fully escort the safe and stable operation of the power grid during the peak summer.

In the summer of 2022, as the temperature continued to rise and the economic situation recovered, the power equipment was also tested. In the past, relying on manual statistical collation, checking data, and exclusion of hidden dangers, not only did the workload, low efficiency, but also inevitably caused omissions. After the company's intelligent production management and control center is launched, 5 RPA applications are developed, and the information of the entire platform's full factor equipment is collected in real time. Relying on the smart monitoring of the device status and the abnormal state of the equipment discovered by the work order, it is used to guide the business departments by digital empowerment. Precisely carry out the investigation and treatment of hidden dangers of equipment defects so that there are counting in the state of the equipment and reducing the burden at the grassroots level.

"110 kV La Nansan No. 2 has a load rate of more than 80%for 5 consecutive days. Please arrange personnel to perform power testing immediately." During the duty, the staff on duty monitors the load of the transmission and transmission equipment through the RPA application every day. When the equipment load rate is mutated, analysts of the Intelligent Production Management Center will comprehensively evaluate the health status of the equipment, and urge business centers to deal with the work centers in a timely manner to quickly eliminate hidden dangers of risks. The overload risk has achieved overload risk from "post -event processing" to "after -to -later" to "after -to -after" The transformation of prevention beforehand.

During the peak summer period, the risk control of power grids is particularly important. In the past, the management department lacked effective process supervision of the implementation of risk management and control measures for grassroots units. Now the analyst of the production control center analysts daily check the inspection records, equipment temperature test records, remote videos, etc. Methods, monitor the implementation of the control measures of each unit during the risk operation of the power grid, and urge each responsible unit to do the special patrol and power -based inspection work under the special operation method, and effectively ensure that during the period of the special operation method of the power grid Essence

Since the Summer, the production control center has used digital means to carry out monitoring and disposal of the load rate of the input and transmission equipment, the risk of the power grid, the risk of major operating risks, the important equipment and the defective equipment during the real -time Duxia, and the disposal Work mode, deep digging the value of the data is the control of the summer management. Up to now, the center of the center has 133 undergone load rates exceeding 80%of the transmission and transmission equipment, 398 special tours in the inspection of the substation, and found 5 risk management and control issues in the power grid. The defect completed the elimination of power before the preservation, and found 10 operating risks, and effectively guaranteed the reliable power supply of the power grid during the high load.

Digital wisdom reinforcement, improve the ability of defect management and control

The health status of the equipment is related to the safe and stable operation of the power grid. In the past, due to the lack of unified platforms to manage the equipment, it may cause some defect management to manage offline offline management, poor shortcomings, and insufficient professional collaboration caused by failing to timely arrange equipment defects within the range of power outages. Repeat power outage and maintenance.

To this end, the Putian Power Supply Company Intelligent Production and Control Center strictly implements the principle of "one stop and multiple use" and "repair must be repaired". Daily monitoring the defect entry and processing of the control platform, according to the rules formulated by the professional departments, marked the key focus on the defects, and and and of. According to the monitoring of the power outage plan, whether to arrange the discharge of the discharge in the range of power outages simultaneously, and continuously track the progress of the elimination of the shortcomings, the responsible unit that fails to eliminate the shortage of the shortcomings shall be warned. , Effectively reduce the risk of equipment operation and improve the level of essential safety.

"According to the equipment that combines the range of power outages from the production control center, we can achieve the power outage arrangement of infrastructure and relocation, eliminate all stock defects within the power outage range at one time, and reach the maintenance cycle within the power outage range to reach the maintenance cycle of the maintenance cycle. The purpose of sporadic equipment simultaneously arranging the maintenance of the maintenance has greatly improved the efficiency of work. "Li Huibin, director of the operation of Putian Power Supply Company, said.

In order to increase the disappearance of equipment defects and prevent repeated power outage caused by the unsatisfactory task due to a single power outage plan. Arrange the equipment consumer shortage plan in advance in advance to ensure that the equipment combined with the power outage and the consumption rate of the power outage is 100%.

At present, the supervision and transmission of the production and control centers combined with the combined power outage plan to reasonably arrange 15 thermal and shortage tasks, combined with the power outage plan to supplement 37 thermal shortage tasks within the power outage range, greatly improving the safety operation level of the equipment, reducing equipment abnormalities, suspension of failure to stop transportationThe number of times and equipment repeatedly stopped the power, which was a solid foundation for stable summer.In the future, Putian Power Supply Company's Production Management Center will continue to use the intelligent transport inspection and control platform as the basis to deeply excavate the value of existing massive production data, promote the integration and development of intelligent, digital technology and power grid equipment management business, strengthen equipment management and control capabilities, give full play to the center of the centerThe important role in the construction of the modern equipment management system to build a new defense line for ensuring the security of the power grid.(Pan Han Xu Hui)
