Therefore, the inspection workload of each employee is greatly increased on the basis of unchanged number of the employees. Due to the fact that main wiring forms and equipment types of all substations are different, the traditional patrol management method for a single substation cannot meet patrol management of a plurality of substations.

With the deep propulsion of the integrated operation and maintenance work of the power transformation, various operation and maintenance works are orderly developed, and the related maintenance work must be integrated while the patrol work is carried out, so that the purpose of saving time is achieved. The traditional operation and maintenance work methods are all carried out item by item, namely, the patrol is taken as a single work and is not generally associated with other maintenance works, and obviously, the mode falls behind.

Various protocols, such as: the equipment regulation, the scheduling regulation, the relay protection regulation, the electric power safety production regulation and the like all provide relevant requirements for inspection work. However, according to the actual situation of the site, such many regulations are inevitably omitted in the process of the site patrol, thereby affecting the quality of the patrol. The requirements for inspection work in a plurality of regulations have similar places and special requirements for different conditions, and are not beneficial to being rapidly mastered, so how to integrate the regulations and compile inspection key points which are beneficial to being rapidly mastered by operation and maintenance personnel is the key for ensuring inspection quality.

According to different maintenance units of the transformer substation, inspection management requirements of the transformer substation are different, in practice, a user transformer substation, a transformer substation to which a state network company belongs, a transformer substation to which a power plant belongs and the like exist, each unit provides own inspection requirements for the governed transformer substation, and a unified standard management method does not exist. And a unified patrol management method is the key for rapid development of a power system in the future.

All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

It should be noted that the embodiments and features of the embodiments may be combined with each other without conflict.

The invention is further described with reference to the following drawings and specific examples, which are not intended to be limiting.

As shown in fig. 8, a substation patrol management method according to the present embodiment includes:

step one, selecting a tour route template in a database according to tour positions, ranges and equipment;

and step two, according to the requirement of the current operation and maintenance and the state information of each device in the patrol template, modifying the patrol route, the patrol step prompt and required tools of the patrol template, and sending the modified patrol route template to the staff of the current operation and maintenance.

In the embodiment, the patrol route template is firstly established, and only corresponding modification needs to be carried out on the template for each specific patrol work, so that a great deal of time is saved, and different personnel can achieve the unification of patrol work according to the unified template; the prompt data of the inspection steps of the equipment are established in the template, and the inspection step prompt is established for each equipment according to the actual condition of the field equipment, so that the inspection key of operation maintenance personnel can be effectively prompted; aiming at each equipment, various regulations are integrated, the inspection steps are comprehensive and reasonable, the condition to be considered for each inspection is given, the on-site practice is necessarily the standard in the arranging process, and the equipment with special conditions is definitely marked to prompt operation and maintenance personnel; integrating the state information of the equipment, knowing the state information of the equipment to be patrolled, including the defects of the equipment, the abnormal condition of the equipment, whether the equipment is operated or not, and further carrying out the next route planning according to the state information of the equipment; and determining the related operation and maintenance work required in the operation and maintenance work according to the transformer substation classification and the related work plan. Through the tour route template, combine this operation maintenance work to launch concrete position, reasonable planning route avoids walking the repetitive path as far as possible, before the tour work begins, relevant equipment is prepared completely, high-efficient completion relevant work. If in the process of inspection tour, the inspection of safety tools and instruments, the inspection of small animal prevention measures, the inspection of fire-fighting facilities, the test of storage batteries, the test of grounding current of a main transformer core, the temperature measurement of equipment and the like can be carried out; and finally, comprehensively planning and planning comprehensively according to the information to obtain the track adopted by the tour.

The inspection routes in the inspection route template of the embodiment include three types, and the inspection templates of the transformer substation are manufactured by integrating equipment maintenance work required to be carried out in the inspection process and inspection requirements of various regulations on equipment through reasonable path planning. And then, a specific accurate patrol route is obtained by combining the template with actual work.

The design principles and the application range of the three routes are as follows:

1. the first type is an S-shaped inspection route around equipment, the inspection route is suitable for equipment fields which are arranged in parallel and are similar in interval arrangement of indoor and outdoor equipment of a transformer substation, the key point of inspection is that an interval unit is used as a unit, and the observation unit equipment is observed to have abnormal phenomena. Generally, the patrol route can be adopted when routine patrol and light-off patrol are performed on substation equipment, and an S-shaped patrol route outside a substation is shown in fig. 1; in the high-voltage chamber or the protection chamber, when a plurality of rows of high-voltage cabinets or protection cabinets exist, the patrol route can also be adopted, as shown in fig. 2, the patrol starts from the lower left corner and finishes when the patrol reaches the upper right corner. The patrol route can fully and comprehensively check the conditions in the high-pressure chamber while saving patrol time, and can also perform related indoor work while patrolling, such as small animal prevention measure check and the like.

In two routine tours or lights-off tours, different tour directions are adopted, the tour for the first time can adopt the directions shown in fig. 1 and fig. 2, the tour for the second time can adopt the reverse tour direction, namely, the tour is started from the high-voltage cabinets in the first row at four intervals of the line, so that the observation angle can reach full coverage within the tour period of one month, and the related requirements are met.

2. The second type is a 8-shaped inspection route around equipment, and is suitable for purposeful special inspection of equipment with a plurality of intervals outside a transformer substation, and the total station equipment is subjected to comprehensive inspection or special inspection. Among them, the types of special tours generally include: when newly thrown into equipment, during overload, during abnormal weather and after failure. The patrol route can cover all outdoor equipment of the substation, the observation angle has no dead angle, the basic patrol unit takes each original as the standard, the equipment needs to be observed carefully, and the direction of the patrol route can be reversed. The second type of tour takes a long time without special conditions, is not recommended to be carried out together with other operation and maintenance work, and needs to ensure the quality of tour. Generally, for a particular tour of a single line interval, the route starts from the lower left corner and returns to the line exit, as shown in the following figure. The schematic diagram of the 8-shaped tour route is shown in FIG. 3;

for the condition that the number of the outdoor intervals of the transformer substation is small and the length of the single line interval is small, a second type of inspection route can be adopted for routine inspection and light-out inspection, as shown in fig. 4.

3. The third type is an O-shaped inspection route around the equipment, and the inspection route is suitable for special inspection of single equipment outdoors in the transformer substation. For the inspection of important equipment, such as the inspection of a transformer, a third inspection route can be adopted; and a third inspection route can be adopted when the outdoor equipment of the substation of the small-sized transformer substation is less. In combination with specific situations, when the indoor equipment is few, the third patrol route is also a patrol route suitable for selection. The tour route is simple, and can be divided into a clockwise route and an anticlockwise route for comprehensively observing the tour equipment. The O-shaped patrol route of the transformer and the protection screen is shown in figures 5 and 6;

4. the relationship of the three kinds of patrol routes is organically combined, namely, a specific route is established according to specific conditions. Such as: in the case of routine inspection, the inspected route includes a defective device, and a third inspection can be taken for the device; the transformer is used as key equipment, and a third inspection can be performed on the body of the transformer; there are devices that have just been operated, for which interval a second special tour may be taken, etc. The three patrol routes should be flexible and specific to specific situations, but should not deviate from the conventional patrol routes. The routine patrol route map of a certain substation is shown in fig. 8, and a specific routine of the routine patrol of the certain substation is determined according to the above contents. The method is carried out in sequence of first indoor and then outdoor.

(1) Indoor route: the high-voltage chamber only has one row of high-voltage cabinets, so that the high-voltage chamber adopts a third inspection route, the inspection process of the high-voltage chamber is required to meet the regulation of relevant regulations, and the inspection is carried out according to the prompting data of the inspection step of the equipment. Two rows of protection cabinets are arranged in the main control room, so that a first tour route is easy to adopt. After two rows of protection cabinets are patrolled, the operation and maintenance work which is carried out indoors through safety appliance inspection and storage battery sampling is carried out.

(2) Outdoor route: starting from the main transformer body, the main transformer body firstly carries out the third inspection, and carries out the grounding current test work of the main transformer core. And performing a first route inspection on other parts of the main transformer primary interval. The first tour route is adopted at the interval of the first route and the third route. And the second line interval is just subjected to switching operation, and special patrol and infrared temperature measurement are required, so that the second patrol route is adopted for patrol. After the sequence of the first line, the second line and the third line is completed in sequence, the first line, the second line and the third line are returned to the primary interval side of the transformer along the bus, and finally the first line and the second line are returned to the transformer body to complete the patrol of the outdoor equipment of the transformer substation.

In the process of patrolling, the bus interval is on the route of the patrolling route, and the third type of patrolling can be completed. Therefore, the routine inspection covers all the equipment outside and inside the transformer substation, and the inspection requirement is met.
