Embodiment Construction

[0023] PSCAD is used as the main simulation program, and third-party simulation software (hardware) is used as the secondary simulation program. The simulation start, end, and the setting of the simulation step are all controlled by PSCAD. The interaction with the outside world is realized through the self-defined module in PSCAD. The function of PSCAD module can only be realized by Fortran language or C language. When C language is adopted, the function interface in C needs to be declared by Fortran language. Because C language is more convenient for system programming, the following specific functions are all implemented in C language.

[0024] 1. Interface composition

[0025] Such as figure 1 , the interface is divided into 3 parts,

[0026] 1. PSCAD collaborative module cosim_interface

[0027] This module is a custom module in PSCAD. Its symbols in the PSCAD schematic diagram are shown as figure 2 .

Abstract

The invention provides a collaborative interface for co-simulation of PSCAD (power system computer aided design) with third-party simulation software or hardware. The collaborative interface is characterized by comprising a collaborative module cosim_interface, set through a custom module of the PSCAD; the collaborative module comprises an interface declaration and an interface module; data interaction between the PSCAD and the third-party simulation software or hardware during co-simulation is achieved through the collaborative module cosim_interface, co-simulation of the PSCAD with the third-party simulation software or hardware is achieved, and the blank that the present PSCAD is in short of co-simulation with otherness of the simulation software or hardware is filled.

Description

technical field [0001] The invention relates to the field of electric power system electronic simulation, in particular to the cooperative interface of PSCAD and third-party simulation software or hardware cooperative simulation. Background technique [0002] Simulation plays a very important role in the research and development of power systems and power electronic equipment. [0003] PSCAD / EMTDC software is widely used in power system electromagnetic transient simulation and power electronic equipment simulation. But it has the following disadvantages: [0004] 1. PSCAD switch devices all use ideal models, it is difficult to simulate the detailed waveforms on the circuit. The semiconductor switches in simulation software such as Saber and Spice use precise models to obtain precise waveforms. [0005] 2. At present, most power electronic control devices use FPGA, and the control codes are mostly written in HDL language. It makes a lot of sense to co-simulate the HDL cod...
