Embodiment Construction

[0049] The core idea of ​​the present invention is to construct a system that summarizes the characteristics of IT equipment, power grid secondary equipment, general software and business software, abstracts public features to form a hierarchical structure, and establishes a business system including the master station end and the substation end of the secondary system. , ICT infrastructure, power grid secondary equipment, and a model with clear syntax and semantic definitions. This model is used to describe the operating status and health indicators of each component of the secondary system. The model is divided into three parts: data model, resource model and dependency model. Among them, the data model solves the description of all software and hardware classifications in the secondary system, the resource model solves the problem of how the model of the secondary system is connected with the primary model of the existing power grid, and the dependency model solves complex a...

Abstract

The invention discloses a power secondary system modeling method and a system. A model which is established according to the method and the system comprises a data model, a resource model and a dependence relationship model. The problems in the three aspects of classification object management, the combination of management object organization and power grid architecture, and the description of a complex relationship are solved. The complexity and the maintenance difficulty, which are caused by the fact that the same model is used to solve the problems in the three aspects, are avoided. Related concepts of an IEC61970 CIM model is introduced into the resource model. Each management object of a secondary system is combined with a power grid primary model. A unified model of primary and secondary models of a power grid are provided. For a business dependence relationship description method, four kinds of basic services are summarized. Public infrastructure services are abstracted. The complex multi-to-multi dependence relationship is decomposed to various kinds of services. Re-organization is carried out under the guidance of finally reflecting the business operation condition. The problem of defining the dependence relationship among a business, software and hardware and between the business and other businesses is solved.

Description

technical field [0001] The invention relates to the field of electric power technology, in particular to a modeling method and system for a secondary power system. Background technique [0002] In the past ten years, with the continuous development of power system and information technology, the monitoring scope of the power secondary system (hereinafter referred to as the secondary system) has been continuously expanded and the technical level has been continuously improved. The advancement of information and communication technology (hereinafter referred to as ICT) has become a major driving force for the development of modern power grid technology. The power secondary system built on the basis of modern information and communication technology has changed the basic structure of power infrastructure to a considerable extent. , and become an important technical guarantee for the safe, reliable, stable and economical operation of the power primary system. In this case, due ...
