Description
Technical Field
The invention relates to the technical field of intelligent patrol of transformer substations, in particular to a remote visual intelligent patrol system of a transformer substation.
Background
Substation intellectualization is an important component of smart power grids, and future substations will be towards the trend of intelligent substations. The transformer equipment is the foundation of the transformer substation, the reliable and safe operation of the transformer substation is related to the production safety and the corresponding social benefit of the transformer substation, and the safety and the stability of the intelligent power grid are greatly influenced. An important link in the transformer substation management work is transformer substation inspection, and the link can inspect the running condition of equipment to master the running rule of the equipment in real time, so that the stable and safe work of the transformer substation is ensured. The substation equipment inspection work and the importance thereof can avoid unnecessary loss if the hidden problem of the equipment can be found in time, and plays an important role in enhancing the safety and economic operation index of the power supply system.
Therefore, the equipment of the substation needs to be checked regularly. However, most of the current transformer substations do not have a unified inspection management method by adopting a paper recording mode, and many disadvantages and shortcomings exist.
(1) Inspection personnel leak inspection. The transformer substation equipment is numerous, and a conventional 220kV transformer substation is generally provided with 2 primary equipment such as a 200kV main transformer, outlet intervals of various voltage levels, a 10kV capacitor, a reactor, PT and the like, and also has secondary equipment such as various protection screens and the like, so that the layout is complex, and inspection workers are easy to miss inspection. The inspection is not detailed enough, and the operators pay more attention to the primary equipment such as transformers, CT, PT and the like, and usually neglect the secondary equipment which is remote in places. Moreover, the transformer substation reserves enough margin from the new production, and many intervals are not put into operation, and the transformer substation needs to be extended according to the economic development in the later operation process, so that inspection personnel can easily miss inspection of new equipment according to subjective experience.
(2) The inspection tool is not uniform. The defects of most equipment such as the heating of a knife switch interface cannot be identified by naked eyes, and the assistance of equipment of an infrared thermometer is needed. The unattended transformer substation is a transformer substation with a plurality of patrol center pipes, each transformer substation cannot be provided with expensive instruments, the transformer substation is uniformly placed in the patrol center, and the transformer substation is carried by patrol personnel when the transformer substation needs to be patrol. However, in daily practice, the inspection personnel easily forget to carry or forget to carry, or forget to perform routine inspection on auxiliary instruments, and often find that the instruments with the past are dead or damaged, cannot be used, and influence the inspection quality.
(3) The inspection time is too short. The inspection content of the power transformation equipment is many, the standard is strict, the inspection is required to be performed strictly, and enough inspection time is required to be ensured. Therefore, the quality of inspection is greatly dependent on the time for the operator to inspect the equipment. The common working intensity before of the operators in the someone duty mode is lower, the workload is greatly increased after the inspection center is established, the number of substations to be inspected is increased, and a part of operators are led to be led to practice during the inspection. The inspection is not in place, responsibility of running inspection personnel is not strong, the inspection work is performed on tigers, work output is not performed, equipment defects are easily seen, and big errors are generated. Therefore, it is necessary to make a scientific inspection route to improve the inspection rate.
Because no person on duty handles on site for the first time when no person on duty substation equipment has an accident, the equipment is inspected, and the fact that the equipment with defects or abnormality is found in time is the important thing in running work. Because a strict inspection standard is not formulated, the inspection standard and the operation method of specific equipment in the transformer substation are not standardized, task information of tasks of each transformer substation equipment is lacking, whether workers carefully and carefully fulfill working obligations is difficult to ensure for daily inspection, special inspection and night inspection, visual management of inspection conditions and corresponding equipment is not facilitated for management staff, the inquiry function is difficult to realize by the traditional paper information recording method, the operation is extremely complicated, and the intelligent operation is completely insufficient. Therefore, it is necessary to design a remote visual intelligent patrol system for the transformer substation.
