“…The aerodynamic model of a wind turbine can be characterized by the well-known C p ( , ) curves. is defined by Tip Speed Wind Speed e r v w (6) Considering the relationship between and C p as the speed changes for a given wind velocity, there is a unique turbine speed which gives the maximum output power. The peak power for each wind speeds occurs at the point where C p is maximum.…”

A simple and efficient position sensorless control method based on feedforward voltage estimation for PMSG improved with multi-parameter estimation using MRAS is proposed in this paper. The dynamically enhanced stator feedforward dq-axes voltages that are derived from steady-state PMSG model are modified for the sensorless drive. In direct-drive wind turbine systems, because of low back-EMF amplitude in the generator output at very low speed operation, the rotor flux linkage cannot be predicted correctly. Vector control is often used in PMSG control, because it has a simple structure and is suitable for various industrial systems. In the power equation, maximum power is obtained as a function of torque and speed. In the proposed method, a variable-speed wind turbine system with back to back converter structure is connected to common DC-link. In this paper, the proposed sensorless control scheme has been implemented with 1 kW PMSG drive controlled by a TMS320F28335 DSP for low speed at 0.1 p.u. (300 rpm) is achieved under multi-parameter variations. Keywords

“…Because of several reasons and advantages [1,8,9,10] for this PM generator, the outer-rotor structure is proposed. This solution gives good cooling conditions for the permanent magnets and they by the drum armature outside the magnets are well-supported [8]. The magnets are glue on the internal drum surface and lead to a simpler mechanical structure of the rotor.…”

“…-Permanent Magnet (PM) generators with rare-earth sintered magnets such as neodymium-iron-boron (NdFeB) are preferred solutions for low speed applications [6,7,9,13]; -The direct drive PM generators is cheaper than the direct drive synchronous generator with electrical winding excitation [2]; -The efficiency of the low speed PM generator is higher and the dimensions are smaller than those of the normal speed asynchronous generator with a gear box or the low speed asynchronous generator [8]. The paper analyses a radial flux low speed PM generator that can easy designed and manufactured by medium size or small companies.…”
