Abstract

The invention discloses a PSCAD-EMTDC simulation model automatic generation method in the field of power system analysis control. The technical scheme is that files described by a G-language (a power system pattern description language) and an E-language (a power system data marker language) are obtained from a national power grid smart power grid dispatching technical support system D5000, then device parameters are obtained on the basis that E-format data of the D5000 are analyzed, assignment of coordinate information in '.psc' files is achieved through data conversion, the coordinate information of a device is obtained by analyzing G-format files, and assignment of the coordinate information in the '.psc' files is further achieved. By adopting the PSCAD-EMTDC simulation model automatic generation method, the defect that the parameter conversion and entering work is heavy and simulation parameter errors are difficult to inspect during manual PSCAD-EMTDC modeling are overcome, and the model generating efficiency and the model generating accuracy are improved.

Description

technical field [0001] The invention belongs to the field of power system analysis and control, in particular to a method for automatically generating a PSCAD-EMTDC simulation model. Background technique [0002] EMTDC (Electric-Magnetic Transient in DC System) is an electromagnetic transient simulation software widely used in power systems. PSCAD is a graphical user interface of EMTDC, which can realize user interaction functions such as graphical modeling and simulation control. PSCAD / EMTDC is mainly used for simulation of electromagnetic transient and control links. At present, the power grid data managed and maintained by the power production department are mainly used for power flow calculation and electromechanical transient analysis parameters. Although the parameters used for electromagnetic transient simulation can be converted from the data used for power flow calculation and electromechanical transient calculation, these The parameters are much more complicated ...
