Power system user defined simulation method facing object program configuration

Abstract

The invention provides a power system user defined simulation method facing object program configuration; the method comprises the following steps: class definition facing the object program configuration; pretreatment of a user defined model; initialization of the user defined model; simulation calculation of the user defined model. The method uses a PSASP to satisfy the demands that mass power system novel elements emerge in the present stage, so flexible modeling simulation methods are needed for large power grid stabile analysis; the novel method expands the power system simulation function, enlarges a power system simulation software usage scope, improves the simulation efficiency, thus further developing the power system simulation software market; in addition, the user defined function is separated from the PSASP, so PSASP sales can be more flexible; by facing the object program configuration design, input / output variable expansion of basic operation functions and UD interface functions can be more conveniently and flexibly carried out, thus continuously enriching existing model database, and strengthening the user defined function.

Description

technical field [0001] The invention relates to a simulation method, in particular to a power system user-defined simulation method based on an object-oriented program framework. Background technique [0002] With the rapid development of power system and power electronics technology, new system components are continuously invested and system control technology is improving day by day. It is required that several new components and various control functions can be simulated in the calculation of power system. General simulation analysis software is equipped with user-defined (UD) modeling and / or third-party software interface functions to realize open simulation of the software and make up for the lack of professional simulation software. [0003] In the existing domestic power system simulation software, the user-defined (User-defined, UD) function technology is relatively backward, and the power system analysis software package (PSASP) has UD functions, but does not use ob...

AI Technical Summary

Problems solved by technology

[0003] In the existing domestic power system simulation software, the user-defined (User-defined, UD) function technology is relatively backward, and the power system analysis software package (PSASP) has UD functions, but does not use object-oriented programs Architecture method, UD function is integrated with power system analysis comprehensive program, it cannot run independently, the program structure is not clear, and it is not convenient for maintenance, function expansion, use and sales

[0004] Foreign commercial software such as matlab, PSCAD, etc. all have user-defined functions, but the implementation mechanism is different from this method, and most of them are simulations with variable step lengths, and there is no method to independently run user-defined functions based on fixed-step simulations
