“…The operating principle is based on a control loop, where the input signal is the electromagnetic torque of the asynchronous motor (AM) and the output signal is the motor speed. The wind speed can be modified through one independent input of the emulator [31]. The block diagram of the wind turbine emulator is presented in Fig.…”

Abstract-This paper is analyzing the operation of a standalone wind turbine system with variable speed Permanent Magnet Synchronous Generator (PMSG) and a system for storing energy during wind speed and load variations. Energy storage devices are required for power balance and power quality in stand alone wind energy systems. Initially, the holistic model of the entire system is achieved, including the PMSG, the boost converter and the storage system. The power absorbed by the connected loads can be effectively delivered and supplied by the proposed wind turbine and energy storage systems, subject to an appropriate control method. The main purpose is to supply 230 V/50 Hz domestic appliances through a single-phase inverter. The simulation results, validated by experimental testing, show a good prediction of the electrical parameter waveforms. The control system is implemented on a dSPACE DS1103 real-time board. Furthermore, the results confirm the stability of the supply.

In actual operation, drive train of wind turbine is not entirely rigid transmission, sometimes flexible characteristics contained. Facing this problem, this paper presents a simulation method on flexible characteristics, which based on closed-loop torque control. Through the method which based on closed-loop torque control, we can make the emulation motor reproduce the flexible characteristics of wind turbine. Results show that this method is effective and feasible. It can reproduce the flexible characteristics of wind turbine properly, and simulation accuracy has been further improved.

“…A graph showing these regions of operation is shown in figure 1 The mechanical model of the turbine system as a whole (usually including the gearbox and appropriate shafts) are also important. There are existing models including higher order effects such as shaft elasticity and gearbox inertia ( [7] [8], [9], [10], [11]), often referred to as "two-mass" or "threemass models", depending on how many significant mechanical components are included in the model. It was determined early in development of the emulator that including these effects in our turbine model was beyond the scope of this project and thus they are neglected.…”

Abstract-In order to provide a testing environment for generator control strategies, a wind turbine emulator was developed. First, a mathematical model was developed for the a 1.5MW wind turbine generator based on available modeling data. Using this data a function relating maximum power output and wind speed was developed along with a one-mass model of the turbine. The model was implemented in a software simulation along with controllers for a DC motor acting as the wind turbine and a dynamometer acting as the generator. The software simulation was implemented in LabVIEW and read in a data file containing high sample rate (20 Hz) wind speed data, calculated the optimal power from that wind speed, and generated control signals for the DC motor and dynamometer.The effectiveness of the controller was found by calculating the mean-square error between the optimal power calculated by the simulation turbine model and the actual power produced by the DC motor/dynamometer combination. Two 800 second wind speed data files were used as test inputs for the emulator: a lowspeed low-frequency wind profile and a turbulent or varyingspeed wind profile. The results of the controller development using these two wind speeds show that the turbine inertia is a significant factor in following the optimal power output of a wind turbine. The time constant of the generator speed-tracking function specified in the modeling data also plays a significant role in how quickly the system can respond to changes in wind speed.
