Chart-model integrated transformer substation and dispatch master station cooperation modeling method

Abstract

A chart-model integrated transformer substation and dispatch master station cooperation modeling method comprises an environment establishing stage and a model establishing stage. According to the method, transformer substation model establishing in a chart-model integrated mode, whole network model integrated processing and seamless connecting can be achieved. On a transformer substation side, a chart-model integrated transformer substation model can guide out transformer substation configuration files which are used for a 61850 transformer substation to carry out configuration. On a master station side, a chart-model integrated power grid model can guide out a CIM, a CIM / E data model, an SVG, a G format transformer substation graph and a geography wiring diagram. The fact that a power grid primary equipment model, a power grid secondary equipment model and graph information are maintained at a transformer substation source end and shared in the whole network is achieved, the shortcoming that currently, the master station side carries out repeated modeling and maintaining on the transformer substation model and the graph is overcome substantially, repeated modeling error probability and production cost are lowered, the consistency and the operability of the power grid model are improved, and accordingly IEC 61850 and IEC61970 standard systematization application is promoted.

Description

technical field [0001] The invention belongs to the field of electric power system and automation thereof, and in particular relates to a cooperative modeling method of a substation and a dispatching master station integrated with graphics and models. Background technique [0002] Intelligent dispatching and intelligent substation are two key links of smart grid. The main station energy management system of dispatching centers at all levels in the power system follows the IEC61970 standard and uses CIM and CIM / E models to describe the grid model. The substation automation system follows the IEC61850 standard and uses the substation configuration description language SCL to describe the substation model. [0003] The IEC61970 series standard defines the application program interface of the energy management system. The purpose is to facilitate the integration of various applications in the energy management system from different manufacturers, to facilitate the interconnectio...

AI Technical Summary

Problems solved by technology

[0011] Duplication of substation construction and dispatching personnel greatly increases redundant work and wastes costs

[0012] To sum up, the difference between the two standard systems makes it difficult to achieve information synchronization and information sharing between the master station of the dispatching center and the substation
