Problems solved by technology

[0004] If it is a large-scale power grid with a large number of nodes, a large number of buses, transformers, transmission lines, and loads, and the connection is complicated, if manual conversion is used, it will consume a lot of manpower, and some calculation errors will inevitably occur in manual calculation conversion, and Very low conversion efficiency
At the same time, due to the model difference between PSASP software and PSCAD software, they cannot be completely corresponding, so that the data cannot be converted

Abstract

The invention discloses an automatic conversion method for converting a PSASP (Power System Analysis Software Package) data model into a PSCAD (Power System Computer Aided Design) data model, and realizes automatic conversion to a PSCAD / EMTDC (Electro Magnetic Transient in DC System) electromagnetic transient model from PSASP electromechanical transient data. The method provided by the invention automatically converts PSASP data and model into PSCAD model data, automatically generates a data file of a PSCAD format, avoids the heavy work of parameter conversion and input during manual modeling, reduces modeling errors, and improves model generation efficiency and model generation accuracy so as to realize a purpose that a large-scale DC power system is subjected to accurate electromagnetic transient analysis.

Description

technical field [0001] The invention relates to the field of power system simulation software, in particular to an automatic conversion method from PSASP to PSCAD data and models. Background technique [0002] Digital simulation is the main method of power system planning, design, operation, control, and fault analysis. Accurate model parameters and calculation methods are the prerequisites for realizing accurate digital simulation of power systems. The current power system digital simulation mainly includes electromechanical transient digital simulation and electromagnetic transient simulation.
