Power grid equipment monitoring big data analysis oriented uniform information model and modeling method

Abstract

The invention belongs o the technical field of power grid automatic dispatch, and particularly relates to a power grid equipment monitoring big data analysis oriented uniform information model and modeling method. The uniform information model includes a resource model and a measurement model; the resource model includes an equipment container, a primary equipment model and an associated secondary equipment model. The modeling method includes the following steps: (S1) using a CIM model in IEC 61970 to describe and establish the equipment container, the primary device model and a correlation thereof, and importing the equipment container and the primary device model and the correlation thereof to the uniform information model; (S2) using an SCL model in IEC61850 to establish the secondary equipment model, and importing the secondary equipment model to the uniform information model; (S3) establishing the correlation between the primary equipment model and the secondary equipment model; and (S4) expanding measurement class information to a measurement package, and establishing a generalized measurement model. The uniform information model can achieve the correlation between primary equipment and secondary equipment, can perform model expansion on measurement classes in the CIM model, can intensively access all the measurement class information, and can achieve uniform modeling.

Description

technical field [0001] The invention belongs to the technical field of power grid automatic dispatching, and in particular relates to a unified information model and a modeling method for big data analysis of power grid equipment monitoring. Background technique [0002] With the comprehensive acceleration of UHV power grid construction, the rapid development of new energy sources and the in-depth advancement of power market reforms, the characteristics of integrated operation of power grids have become more and more obvious. Centralized analysis and decision-making, multi-professional business collaboration and cross-dispatch agencies are implemented for power grids. The need for work collaboration is more urgent. In recent years, the information resources that can be obtained by the power grid dispatching control center have become more and more abundant, and there are more and more information sources available for monitoring and analysis of power grid equipment, and the ...
