Embodiment Construction

[0026] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0027] A consistency verification method for distribution network historical data service interface, based on the object management organization OMG, data access tool DAF, and industrial system historical data access standard HDAIS, on the basis of supporting the object-oriented general information model CIM, matching The historical data standardization access interface of the power grid system conducts a specification consistency test. If it fails, it will feed back an error message and wait for modification until it succeeds.

[0028] The specific steps of the method are:

[0029] 1) Create HDAIS service object;

[0030] 2) Check the HDAIS interface, including: consistency check, data read check, data update check, entry attribute read check, label check, data replay check, data object discovery check, One or more of data model discovery v...

Abstract

The invention relates to a power distribution network historical data service interface consistency verifying method. The method includes the steps that standard consistency testing is carried out on a historical data standardized access interface of a power distribution network system on the basis of supporting an object-oriented common information model (CIM) through an object management group (OMG), a data access facility (DAF) and an historical data access interface standard (HDAIS) of an industrial system; if the testing fails, error information is fed back, and errors wait to be corrected until the testing succeeds. The method is accurate in verification, consistency verifying is carried out on the system interface comprehensively, intersystem accessible historical data access is ensured, and resource sharing is ensured. The historical data access interface can be verified efficiently and comprehensively, development efficiency can be improved by two times according to the actual number of interfaces supported by a system, resources are saved, and the development and maintenance cost is lowered.

Description

technical field [0001] The invention relates to a method for verifying the consistency of a historical data service interface of a distribution network. Based on the OMG HDAIS standard, the historical data service interface is standardized and verified. Background technique [0002] The historical data access service of the distribution network system must follow the uniform standard interface HDAIS. HDAIS is an international standard issued by OMG. The HDAIS interface defines a series of operation interfaces for time series data management and access, so that various applications in the system can generate and use these historical data. This interface can provide historical data access or services based on time series, such as one day, one week or longer. A typical example of applying historical data in distribution network business applications is load forecasting. The realization of power load forecasting needs to be based on the changing trend of historical data. HDAIS...
