Abstract

The invention provides a method for automatically converting electromagnetism transient models and element pictures from a PSCAD (power system computer aided design) to an ADPSS (advanced digital power system simulator). The method comprises the following steps of determining coordinates of endpoints of elements; performing topology analysis to determine a connection relation between the elements; automatically generating an electromagnetism transient model of the ADPSS; and forming an intermediate file of the ADPSS. By the method for automatically converting the electromagnetism transient models and the element pictures from the PSCAD to the ADPSS, the existing data files of which the format is PSCAD are directly converted into intermediate data files of a simulation procedure of the ADPSS, and the purpose of efficiently and accurately simulating and analyzing a large-scale alternating-current and direct-current power system is achieved.

Description

technical field [0001] The invention relates to a conversion method, in particular to an automatic conversion method of electromagnetic transient models and component graphics from PSCAD to ADPSS. Background technique [0002] For AC and DC systems, in order to facilitate the study of electromagnetic transients and control links, it is necessary to establish a simulation model of AC and DC systems. PSCAD / EMTDC is one of the commonly used electromagnetic transient simulation programs for AC and DC systems in China. It can not only study AC and DC power system problems, but also complete power electronics simulation and nonlinear control. However, the use of PSCAD / EMTDC electromagnetic transient calculation program also has certain shortcomings. Due to the limitations of its algorithm, there are problems such as small simulation scale when using PSCAD / EMTDC to simulate AC and DC systems. [0003] All-digital real-time simulation device for electric power system (ADPSS) is an ...
