Abstract

Abstract: The transient characteristics of wind turbine generator have great influence on the stable operation of renewable energy base and the power grid in the near region, therefore it is of great significance to build accurate wind turbine generator model for large scale renewable energy integration. However, current wind turbine generator model mostly adopt typical model, some differences exist between the model and the real wind turbine generator, dissatisfying the demand of power system simulation. This paper presents a new EMT modeling method of "filed test - control hardware in the loop(CHIL) - dynamic link library(DLL)" for wind turbine generator. CHIL simulation platform based on FPGA is built and the accuracy of CHIL modeling is verified by filed test. Furthermore, a controller-less digital modeling method based on dynamic link library is proposed with the controller code packaged in the digital model, thus, the EMT model of wind turbine generator is realized and the two level time domain consistency verification proves the feasibility and accuracy of this modelling method.

Key words: wind turbine generator, electromagnetic transient model, control hardware in the loop, dynamic link library
