Embodiment Construction

[0027] Services that know the relationship of entity attributes allow external applications, such as navigation or data access, to perform consistency checks on relationships stored in external storage data before triggering functions, or to perform continuous checks.

[0028] Figure 1 shows the setup of the consistency verification system. The external storage stores a collection of reference containers, which hold reference models of entities in different IT systems. The setup of the reference container is shown in more detail in FIG. 4 . Entities are assigned an entity type, which holds a list of available properties. Each entity type may be assigned a list of key attributes for attribute consistency. If access is required to a certain entity of a particular IT system, that entity can be addressed and details about that entity can be obtained from that IT system. There are multiple adapters for each IT system that allow pinging of the system's data sets. The signal sent...

Abstract

Attribute consistency works on the comparison of a reference value against the online value of the attributes, which are retrieved from the corresponding system. In order to know which attributes need to be considered for consistency, a list of relevant attributes of each entity type in each application is stored together with the reference value of the entity. This attribute list is used by the consistency service. Therefore several attribute values of one entity in one system can be included in a combined 'hash' value. At start-up or in the engineering phase, this reference value is computed out of the defined attribute list. At the time of a consistency check, the values of the attributes are read and a 'hash' value is calculated with the same algorithm as the reference value. If those two values differ, an inconsistency occurred. The inventive method allows validating consistency of attributes of an entity in one of the participating applications. Any inconsistency can be propagated to all other participating applications which then may trigger functionality accordingly.

Description

technical field [0001] The present invention relates to the field of utility automation. [0002] It concerns a method of verifying the consistency of entities stored in datasets of many different IT systems used to operate utility automation entities. Background technique [0003] As energy markets deregulate, the focus of utilities shifts toward optimizing internal business processes. On the IT systems side, navigating, synchronizing and retrieving information stored in the various data sources where work is performed (eg SCADA - Supervisory Control and Data Acquisition, CMMS - Computerized Maintenance Management System, GIS - Geographic Information System) is challenged. [0004] All applications affect the same "scope of expertise" - the physical assets in utility operations such as stations, lines, transformers, circuit breakers, zones and regions. Various applications can be used to model these assets and assign them specific attributes. However, uniform access to t...
