one、Background
The pain points of substation operation and maintenance are as follows:
1) Real time monitoring is difficult, and daily inspections and maintenance operations cannot be monitored in real time. Currently, traditional work modes are still used, which can only replay and investigate the reasons afterwards, and cannot track the entry personnel in real time. Supervision is cumbersome;
2) Lack of visual management, unable to real-time understand the on-site operation situation and equipment status when dividing the operation and maintenance work area, basically using video monitoring methods, unable to link and view equipment information for management;
3) Difficulty in event tracing, intelligent event tracing relies on monitoring playback, difficult evaluation of monitoring blind spots, multiple management systems are independent of each other, lack correlation analysis, and rely more on manual management on site or in the background;
4) Work safety is not guaranteed, and dangerous behaviors such as crossing boundaries, misunderstandings, and operational errors cannot be alerted in real time. The utilization rate of video surveillance is low, and maintenance mainly relies on fence protection. The preparation work is cumbersome and there is a risk of power supply.
two、solution
Yunzhan is based on the concept of digital twins, with an active environmental safety warning system as the core of construction. Through 3D visualization, the overall structure and equipment distribution of the substation are accurately modeled in a 1:1 ratio, and real-time status data is associated and mapped with the model to realistically restore the scene and meet diverse display needs. It can present the real environment image realistically in front of the eyes.
The advantages of the plan are as follows:
1) Efficient operation and maintenance, intelligent cloud inspection
The digital twin system can reflect the real-time operation status of substation equipment, and the equipment status information is fully controlled. The operation and maintenance personnel can conduct "intelligent cloud inspection" in the command center, realizing remote operation and maintenance, automatic warning, and auxiliary decision-making, effectively improving the real-time perception ability of substation equipment and environment panorama, and bringing revolutionary changes to the safety operation and maintenance management mode of substations, truly realizing unmanned operation.
2) Fault analysis, advance warning
Comprehensive monitoring and management of various devices within the digital twin system. Potential hazards such as overheating and discharge during operation can be alerted in advance, and the current equipment status can be quickly identified to locate defects. This enables proactive detection and precise handling, thereby improving the efficiency of emergency fault handling and effectively shortening the repair time. Combined with user work order information, real-time monitoring of work order processing progress, on-site maintenance screen tracking, and fault repair results can be achieved, providing objective basis for the repair process and plan sorting.
