“…The emulators are built either in full size, i.e. in the MW-range [76], or on a laboratory scale, ranging from sub-kW applications [77][78][79][80][81][82][83] through a few kW [84][85][86][87][88] up to 10 kW [75,89,90] and 20 kW [91,92]). Other concepts simulate the whole drive train as well as control system, therefore, only the grid connected power converter is present as physical device, enabling to simulate full-scale turbines while using smaller power converters through scaling [93,94].…”

“…The known inputs of the first modeling are the torque coefficient of wind turbine and wind turbine radius R , while the known inputs of the second modeling are intrinsic parameters of the wind turbine. Many researchers have made the related research of the wind turbine modeling in [1][2][3][4]6]. However it is difficult to model based on the torque coefficient because the wind turbine torque coefficient is unknown, and the only coefficient is the manufacturing parameters of the blade which may be obtained from the manufacturer.…”

“…It not only has the same mechanical characteristics with the actual wind turbine, but also provides controllable equivalent wind energy. So it can be used in the design, estimation and test application of the WPGS, which greatly improves the efficiency and validity of research and development [1][2][3][4].The key of the wind turbine emulator system is the establishment of the wind turbine output torque model which can be applied to any wind speed input varying with time and space.…”

Abstract. In the laboratory without the condition of actual wind farm or wind turbine, building a wind turbine output characteristic emulation system can provide an effective way for the research on WPGS. Firstly the wind turbine torque model was built, redistributed the bladed element by weight coefficient and calculated the wind turbine torque based on the blade element theory. Then characteristics of the wind turbine were emulated by controlling the DC motor armature winding current. So the wind turbine emulator based virtual wind was built. Finally the experiment platform of VSCF WPGS was also built. The experiments not only confirms the correctness and superiority of the detailed wind turbine model, reflects the rapid tracking performance of the emulated torque, but also simulates the wind turbine to meet the research of VSCF WPGS such as the sub-synchronous or super-synchronous running of DFIG, consequently verifies the correctness of the control strategies for variable speed constant frequency WPGS.

For a variable-speed wind power generation system equipped with the fixed-pitch wind turbine and doubly salient electro-magnetic generator (DSEG), the rotational speed can't be changed by pitch control. In this paper, a novel speed control method based on excitation current control of DSEG wind power generator (DEWG) in full range of wind speed is studied, based on their characteristics. It is composed of three-stage methods, which are maximum power point track (MPPT), constant speed control and constant power limit. So the safety, efficiency and stability of the whole system can be ensured. Effectiveness of the proposed methods is verified by Hardware-in-the-Loop (HIL) simulations, which adopt the real controller and real time simulation platform.Keywords -DSEG; wind power generation system; full range of wind-speed; speed control; three-stage method I. INTRODUCTION DSEG is a novel type of brushless DC machines, with the advantages of simple structure, flexibility control, and high efficiency, etc. Its application in wind power system will cut down the cost of generating and improve the reliability of system.The speed control method in full range of wind speed is needed to ensure the safety, efficiency and stability of the whole system. At present, a number of existing methods have been used in speed control of wind power system already. The method of pitch control changes the attack angle by adjusting the pitch angle of the blade. Further, the power and torque captured by wind turbine are controlled. This method can maintain constant output power in high wind speed range. However, the control system is complex and a variable distance mechanism is needed. Using the stall performance of the blade profile, the stall control method can limit the output power without a variable distance mechanism. But the stall degree deepens with increasing wind speed, so it hardly keeps constant output power in high wind speed range.Compared to the conventional permanent-magnet machine and doubly-fed induction generator wind turbine, the torque of DSEG can be controlled by adjusting the excitation current so a quicker response
