Abstract

The invention relates to a wind power generation converter semi-physical simulation platform, which comprises an upper computer, a controller, a real-time simulator, a human-computer interface and an oscilloscope, and is characterized in that the upper computer is respectively connected with the controller and the real-time simulator, the real-time simulator is also connected with the oscilloscope, and the controller is also connected with the human-computer interface; the real-time simulator is used for building a converter model required by testing; the upper computer is used for inputting external data for testing the converter in wind power generation to the converter model; the controller is used for compiling a switch control strategy required to be tested, outputting an SPWM signal and transmitting the SPWM signal to the real-time simulator; the oscilloscope is used for displaying the output waveform of the real-time simulator; and the human-computer interface is used for generating and transmitting an operation instruction to the controller. Compared with the prior art, the method has the advantages that the development cost is low, the simulation step length is smaller, the electromagnetic transient process of the switch can be simulated, and the loss of the switch can be simulated more accurately.

Description

technical field [0001] The invention relates to the technical field of wind power converter simulation technology, in particular to a half-physical simulation platform for wind power converters. Background technique [0002] The hardware-in-the-loop simulation platform for wind power converters belongs to the real-time simulation platform. In order to improve the accuracy and credibility of the simulation, some foreign companies have developed a real-time simulation platform based on FPGA. For example, the dSPACE real-time simulation system is a control system simulation test platform developed by the German dSPACE company, which is compatible with Matlab / Simulink / RTW and realizes seamless connection; RT-LAB is a model-based engineering design application platform that realizes engineering projects. The design, real-time simulation, prototype and hardware fast in-loop test; the iHawk real-time simulation work platform developed by American Parallel Computer Corporation is ba...
