“…Reduced-order methods have been well studied in the area of control, fluid dynamics, structural analysis, etc. [8][9][10]. A number of ROMs have been developed for wind farms [11,12], but these models have only focused on modelling the drive train (DT) dynamics within the wind farm.…”

At present, over 1500 offshore wind turbines (OWTs) are operating in the UK with a capacity of 5.4GW. Until now, the research has mainly focused on how to minimise the CAPEX, but Operation and Maintenance (O&M) can represent up to 39% of the lifetime costs of an offshore wind farm, mainly due to the assets’ high cost and the harsh environment in which they operate. Focusing on O&M, the HOME Offshore research project (www.homeoffshore.org) aims to derive an advanced interpretation of the fault mechanisms through holistic multiphysics modelling of the wind farm. With the present work, an advanced model of dynamics for a single wind turbine is developed, able to identify the couplings between aero-hydro-servo-elastic (AHSE) dynamics and drive train dynamics. The wind turbine mechanical components, modelled using an AHSE dynamic model, are coupled with a detailed representation of a variable-speed direct-drive 5MW permanent magnet synchronous generator (PMSG) and its fully rated voltage source converters (VSCs). Using the developed model for the wind turbine, several case studies are carried out for above and below rated operating conditions. Firstly, the response time histories of wind turbine degrees of freedom (DOFs) are modelled using a full-order coupled analysis. Subsequently, regression analysis is applied in order to correlate DOFs and generated rotor torque (target degree of freedom for the failure mode in analysis), quantifying the level of inherent coupling effects. Finally, the reduced-order multiphysics models for a single offshore wind turbine are derived based on the strength of the correlation coefficients. The accuracy of the proposed reduced-order models is discussed, comparing it against the full-order coupled model in terms of statistical data and spectrum. In terms of statistical results, all the reduced-order models have a good agreement with the full-order results. In terms of spectrum, all the reduced-order models have a good agreement with the full-order results if the frequencies of interest are below 0.75Hz.

“…A lot of research work on modeling and simulation of DFIGs has been done both at home and abroad, literature [2] established overall dynamic mathematical models of wind, wind turbine, doubly-fed asynchronous induction motor, converter and electrical control part of VSCF WTGs , just as shown in figure 1, but considering that because of high order of generator model, when conducting simulation with large wind farms models, the problem of dimension disaster may occur , literature [3] deduced the detailed reduced-order generator model, and discussed its application value in power market. VSCF wind power generation control unit focuses mainly on generator rotor field voltage control and wind turbines blade angle control, the goal is to make mechanical parts of the wind turbine cooperate with electrical parts of the generator, thus enhance the efficiency of converting wind energy to electricity and improve the power quality.…”

In order to build an aggregated wind farm model to research on the effect large scale wind power has on the transient performance of the power system, firstly, it is necessary to build an effective WTGs model. Based on the electro-magnetic transient simulation platform PSCAD/EMTDC, this paper built models of all the parts of Doubly-fed type VSCF wind generator, including wind model, wind turbine model, rotation system model, detailed converters model, and emphatically expounded the implementation process of the control strategy based on the stator flux vector oriented principle. Then through the change of wind speed and setting three-phase short-circuit fault on the net side, the model is verified on the decoupling control of active and reactive power for maximum point power tracking (MPPT) and the ability of low voltage ride-through.
