Problems solved by technology

In the existing field of power system modeling, automation personnel start modeling the power system locally, first modeling the electrical components in the substation, and then combining multiple electrical components into an interval model, and then Multiple bays are connected through busbars and transformers to form a substation model, that is, after storing the information of each electrical component in the database, a bay model is built for each electrical component in the database, and then a substation model is generated. The modeling method needs to perform many repeated modeling operations on electrical components, and then build intervals for each electrical component. The process is cumbersome and complicated, which consumes a lot of work and is inefficient.
In fact, by comparing and analyzing the various models of the substation, it will be found that in the same substation, the same voltage level, the same type (with the same topology) of the interval, many of their parameters are the same, for example, which Devices need to collect telemetry, which devices need to collect telesignals, which protection signals are in this interval, etc. These parameters are basically the same, that is to say, this modeling method in the existing technology is actually repeated a lot If the substation can be modeled with intervals instead of electrical components as the basic unit, the efficiency of power modeling will be greatly improved. At present, there is no effective power system construction with intervals as the basic unit. Modular schemes emerge

Abstract

The invention provides electric system modeling method and system. The electric power modeling system is modeled by using an interval as a basic unit. Aiming at the intervals of same type with same topological structure, an interval model is established for one of the intervals of the type, then other intervals are generated by using the interval model, and a substation model is formed by connection of buses, transformers and the like by using the intervals after the intervals are generated. For the intervals of the same type, the topological structures and many parameters are same, other intervals are generated by using one interval model as a template interval, therefore, the invention has convenient and quick operation and less workload; and compared with the traditional modeling mode using an electric element as a basic unit, the invention greatly reduces the workload and improves the efficiency of the electric power modeling.
