A Judgment Method of Power Outage Period Based on Historical Data Statistics

Abstract

The invention discloses a power-cut construction period judgment method based on historical data statistics. The method comprises the steps that actual construction period time of all equipment under different work content at different voltage classes in different power-cut places in recent years is extracted; on the basis of the actual construction period time, timeliness of data is considered, and an original standard power-cut construction period is modified to acquire a more reasonable standard construction period setting value; and then, construction period judgment is performed on a power-cut plan currently input into a power-cut information management system, and whether the current construction period setting of the power-cut plan is within a standard construction period range or not is judged by performing key field mapping on the plan and comparing the plan with a corresponding power-cut construction period standard. Through mapping and statistical modification on historical data, a more reasonable construction period standard is used for judging whether time arrangement of a future power-cut plan is reasonable or not, a criterion is provided for a power supply company, and the accuracy of construction period setting can be improved.

Description

technical field [0001] The invention relates to a method for judging a power outage duration based on historical data statistics, in particular to a key field mapping for data information in a historical power outage database, and belongs to the technical field of power outage duration judgment. Background technique [0002] The software architecture can usually be divided into three layers: interface presentation layer, business logic layer and data access layer. Usually in the enterprise application development environment, the object-oriented development method has become the mainstream method. Objects only exist in memory. If you want to save object data permanently, you need to persist the object, that is, store the object in the database. Conversely, data needs to be loaded from the database and constructed as memory objects. At present, the relational database is still the mainstream and the most widely used database, and the form of its data storage is non-object-o...

Problems solved by technology

Manually writing and maintaining the mapping and conversion code of the data access layer, due to the differences between compatible database types (Oracle, Sql Server, DB2, Sybase, etc.) and versions, etc., this will undoubtedly be a tedious and time-consuming task

[0003] Moreover, for data in business application systems, due to reasons such as efficiency and space, one type of data often needs to define multiple entity object types, and the definition, conversion, deployment, and maintenance of these object types are also relatively cumbersome. Communication requirements require a common unified data format and object form to encapsulate data

[0004] In addition, the power supply company currently does not have a high degree of utilization of historical power outage data, and seldom makes effective judgments on the set value of the power outage period after generating the outage plan, and the length of the construction period is generally set based on experience. The time arrangement is not scientific enough, it is necessary to improve this problem
