Embodiment Construction

[0028] On the basis of CIM, refer to the relevant standards of China Southern Grid, and expand and define a unified model UCIM. On the basis of CIM, UCIM mainly expands the secondary equipment, fixed value, generalized measurement model for various professional information, and job-related descriptions.

[0029] 1. Power system resource model

[0030] The power system resource model is mainly based on equipment containers and primary equipment. The equipment container model adopts three layers: plant station, voltage level, and interval. Conductive equipment with a clear voltage level is placed under a specific voltage level interval, across voltage level objects and plant stations. The main object can be directly placed in the bay directly belonging to the power station, such as the main transformer bay where the main transformer is located can directly belong to the substation. The equipment model mainly includes: primary equipment such as transformers, switches, switches, ...

Abstract

The invention relates to a unified modeling method employing a generalized measuring transverse correlation mode. The unified modeling method is characterized by comprising the following steps of grid equipment modeling, secondary equipment modeling, primary equipment and secondary equipment correlation establishing, asset modeling, other-data abstract modeling, generalized measuring model establishing and meta-model defining, wherein secondary equipment modeling is conducted according to the IEC61850, and a PSR is used as the center of a generalized measuring model. The method is also applicable to unified modeling of an automated system of all related information in a power system. The method increases the software development efficiency and accuracy, shortens the development cycle and realizes power grid model unification, a complete data platform is provided, the flexible metadata mechanism is adopted, a multi-layer system framework for services is used, and therefore convenience is brought to electric power information resource sharing.

Description

technical field [0001] The invention is applied to the dispatching automation field of various electric power systems, particularly relates to the unified modeling of the related automation systems of the inspection and maintenance center, and is also applicable to the data integration of other automation systems. Background technique [0002] China Southern Power Grid has continued to carry out in-depth research and pilot application of substation operation and maintenance technology. The substation cockpit is an integrated technology platform for substation operation and maintenance, integrating professional technical system information such as substation monitoring, control, equipment monitoring and maintenance management. Since the System Operation Department of China Southern Power Grid Corporation led the research on the cockpit technology of comprehensive operation of the power system, more and more attention has been paid to the inspection and maintenance center respo...
