Abstract

The invention discloses a method for converting data of a power network system from PSS / E (power system analysis / emulation) to SimPowerSys. The method comprises the steps of: (1) connecting information, static power element parameter information and dynamic power element parameter information from a power network in a PSS / E data file, obtaining and forming power network layout information; (2) dividing the area of the power network system and forming a sub-module within each area, and arranging a busbar unit according to the position information of the sub-module and coordinate information of the busbar unit within each sub-module, and (3) wiring the busbar unit. According to the method for converting data of the power network system disclosed by the invention, original data in the PSS / E file are utilized; automatic generation of a simulation model of the SimPowerSys power system is achieved, manually converting or recompiling a great number of data files is not needed, the model compiling process is greatly simplified, the compiling error is reduced and the work efficiency is improved.

Description

technical field [0001] The invention relates to the field of power system simulation calculation, in particular to a power network system data conversion method from PSS / E to SimPowerSys. Background technique [0002] With the development of DC transmission technology and the investment of multiple DC lines, my country has invested in multiple high-voltage DC transmission lines, especially the East China Power Grid and the Southern Power Grid have formed a multi-infeed large-scale AC-DC interconnection system. For the calculation and research of this kind of power system containing power electronic devices, the conventional electromechanical transient program has certain limitations. In order to truly reflect the detailed response characteristics of AC and DC systems under various fault conditions, it is necessary to adopt an electromagnetic transient program that can be accurately simulated. [0003] PSS / E is one of the commonly used electromechanical transient simulation ...
