Description

Intelligent binding method for power grid maintenance application form

Technical Field

The invention relates to an intelligent binding method for a power grid maintenance request form, and belongs to the field of power grid information integration.

Background

The equipment maintenance arrangement in the current power grid is mainly based on a monthly maintenance plan compiled after the monthly production maintenance power failure balance can be uniformly balanced, and related maintenance units propose daily maintenance plans according to the field reality and the monthly maintenance plan and manage the maintenance plans when the maintenance working day is close

The system fills in a maintenance request form, transacts equipment outage or starts an application procedure for the abnormal equipment. The maintenance request sheet comprises information such as the name of the outage equipment, working content, power failure range, safety measures, planned power outage and power transmission time and the like, and is transmitted to a link to be executed of a dispatching desk after circulation approval of links such as a reporting unit, a carrier, protection approval, center leaders and the like. After the maintenance application form formally approves execution, a dispatcher plans to write a power-on/off instruction ticket according to the maintenance application form, and handles start-up, completion and termination on the maintenance application form in the maintenance working process, so as to realize closed-loop management on the maintenance work.

Because the electric wire netting equipment is numerous, and because uncontrollable reasons such as bad weather, equipment defect, on-the-spot actual overhaul is difficult to follow the maintenance plan strictly, numerous and the maintenance application form that goes on simultaneously cause very big puzzlement for each professional examination and approval personnel and regulation and control executive personnel, current main drawback summary as follows:

firstly, the method comprises the following steps: in order to avoid repeated power failure of the same loop or the same equipment, a power failure of construction and capital construction and the like, related special duty of a fortune teller and the like needs to combine planned maintenance work with technical improvement countermeasures, power failure of capital construction and the like during examination, approval and maintenance application form, and meanwhile, power grid safety constraint and boundary conditions need to be considered, so that the power grid safety structure is prevented from being excessively influenced by the maintenance work. Therefore, it is important to reasonably arrange the time span and sequence of the maintenance work, and it puts high demand on professional literacy of related personnel

II, secondly: for the maintenance application form to be executed, due to the fact that safety measures are overlapped in multiple maintenance works of the same transformer substation and the power-on and power-off time ranges are crossed, a dispatcher needs to comprehensively browse all related applications of the substation when drawing up an instruction ticket, the approval opinions of examination and approval personnel of each node are fully understood, the instruction ticket is drawn up according to the safety measures of each time node, meanwhile, feasibility of actual operation and economy of power grid operation need to be considered, the work of drawing up and browsing the application form in dispatching is complex and low in efficiency, and once the contents of the application form are omitted or misunderstood, the safety of the power grid can be seriously affected.

And thirdly, the scattered and unrelated maintenance application forms can only be integrated manually, so that the development of the follow-up intelligent billing function of the power grid is hindered, and the further improvement of the intelligent and automatic level of the power grid is influenced.

In the actual maintenance production process, except the scheduled maintenance application, temporary applications such as combined application and urgent defect elimination application exist, the examination and approval and the execution of the temporary applications need to be comprehensively planned with the scheduled application, the overall execution is realized, and the work difficulty of each professional is further increased.

Example two

Referring to fig. 2, further, the specific steps of binding or placing the temporarily submitted maintenance request form and the planned maintenance request form into a single-listed application library according to the relevance include:

The method adopted by the embodiment is that the working content field is taken to be compared with the safety measure fields in the planned overhaul application library and the temporary application library in a fuzzy mode for retrieval, and independent binding is carried out or the working content field and the safety measure fields are merged into the original application binding package when the working content field meets the condition that the time coverage and the safety measure fields have the same 'XX equipment'.

Fourth-level binding, wherein if a temporarily submitted maintenance request form cannot be contained in any binding package in the third-level binding, the fourth-level binding is carried out, the maintenance time and the safety measures in the field content of the temporarily submitted maintenance request form are extracted, the maintenance time and the safety measures of all the single-column request forms are traversed, and if the maintenance time of the temporarily submitted maintenance request form is overlapped with that of the single-column request form and the safety measures have the same category, the temporarily submitted maintenance request form and the single-column request form are packaged into a new binding package;

fifth-level binding, if a temporarily submitted maintenance application form cannot be packed with any single-row application form into a new binding package in the fourth-level binding, performing fifth-level binding, extracting the equipment topological relation and maintenance time in the field content of the temporarily submitted maintenance application form, acquiring the name and number of secondary equipment of the equipment in the temporarily submitted maintenance application form according to the equipment topological relation, traversing the maintenance time and safety measures of the maintenance application form in the new binding package generated in the fourth-level binding according to the name and number of the secondary equipment and the maintenance time, and if the maintenance time of the temporarily submitted maintenance application form is overlapped with the maintenance time of the maintenance application form in the new binding package and the name and number of the secondary equipment appear in the safety measures of the maintenance application form, incorporating the temporarily submitted maintenance application form into the new binding package;

the dispatcher station is focused on tracking the maintenance request form process. The time field of all the overhaul application sheets in the same bundle is changed from overhaul time to application approval time. The bundle package is recalculated according to the actual progress of each application form and is displayed on the same interface, as shown in fig. 4.

According to the embodiment, the functions of examination and approval verification and post binding verification are added, the error checking prevention and manual correction of binding results are realized, and the accuracy and operability of binding of the application form are improved.
