“…( [3], [5], [7], [8], [10], [14], [15], [16], [17]). To produce the mechanical power, the most common type of motor used was the DC motor due to the direct relationship between motor torque and rotor current.…”

“…Obviously, for any given target power point there are a large number of torque and speed combinations that will yield a valid result. Based on current literature ( [3], [8]), the common "division of labor" between the turbine control and generator control is to allow the generator to regulate the shaft speed and the turbine to regulate the torque. This technique was applied when developing the controllers for each unit.…”

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.

“…The proposed WPSS based on modules can become results for experimental results are unclear [10]. In [11], the pitch-influenced characteristics of generator output are illustrated in experimental results. Nevertheless, the WPSS in this paper can show only fixed-pitch characteristics without pitch control for power regulation.…”

This paper presents a module approach for lab-scale wind power systems (WPS). The system is designed into functional modules. These modules can be used independently or in other projects. It is also convenient to handle and set up them on a small table in classrooms and labs. Hence, they are very useful for training and research. In addition, operation on both aerodynamic side and generator side is developed in this research. Many papers on wind system simulators focus only on aerodynamic system with pitch angle control or generator system with optimal control. Thus, the operation of WPS in 2 regions, which requires coordination of aerodynamic and generator sides, is not explained and demonstrated in previous study. Many case studies are conducted to demonstrate the capability of the module-based WPS. The system is capable of speed control, optimal power control and pitch angle control. As illustrated in experimental results, these control strategies can efficiently cooperate under operation in 2 regions of WPS.

“…This variable-frequency AC power is converted into a 60 Hz AC power and is connected to the power grid through the converter and inverter. [8,9] Previously developed hardware simulators calculated turbine torque using offline wind data. Thus, it is not possible to analyze the operational characteristics of a PMSG wind power system in real time.…”

-This paper describes a real-time hardware simulator for a grid-tied Permanent Magnet Synchronous Generator (PMSG) wind power system, which consists of an anemometer, a data logger, a motor-generator set with vector drive, and a back-to-back power converter with a digital signal processor (DSP) controller. The anemometer measures real wind speed, and the data is sent to the data logger to calculate the turbine torque. The calculated torque is sent to the vector drive for the induction motor after it is scaled down to the rated simulator power. The motor generates the mechanical power for the PMSG, and the generated electrical power is connected to the grid through a back-to-back converter. The generator-side converter in a back-to-back converter operates in current control mode to track the maximum power point at the given wind speed. The grid-side converter operates to control the direct current link voltage and to correct the power factor. The developed simulator can be used to analyze various mechanical and electrical characteristics of a grid-tied PMSG wind power system. It can also be utilized to educate students or engineers on the operation of grid-tied PMSG wind power system.
