The invention relates to a transformer substation model construction method based on a BPA element model, which comprises the following steps: constructing a voltage class index, and establishing an association relationship between equipment and voltage classes; judging whether a bus model is generated or not according to the number of the devices connected with the connection points; establishinga transformer substation model according to the connection points of the transformer elements or the series compensation connection points; and establishing an association relationship between the line and the transformer substation. According to the association relationship between the voltage level and the equipment, the association relationship between the line and the transformer substation and the relationship between the connection point and the equipment, the substation module with clear layers is constructed, the problems that when a BPA element model is adopted to construct a substation at present, the layers are not clear, and positioning, searching and other aspects of equipment on a substation graph are extremely inconvenient are solved, and graph-model association is facilitated.
Description
technical field [0001] The invention relates to the technical field of power system automation, in particular to a method for building a substation model based on a BPA component model. Background technique [0002] BPA is an electromechanical transient simulation tool. Its model is saved in files with the extension dat and swi. The files contain primary equipment information and area information such as transformers, lines, loads, generators, capacitors / reactances, etc. These primary equipment pass through Ports are connected to each other to form a topological connection point represented by the name of the B card. The BPA model is a flat model and lacks hierarchy. [0003] BPA's model is a flat model, lacking layers. When drawing power flow diagrams, BPA provides a way to create substation primitives by manually gathering nodes. There is no support for substation models at the bottom layer. In terms of model management, graphics generation, substation filtering, hierarch...
