Modelling of a Generation System with Coiled Rotor Synchronous Generator for Renewable Energy

Abstract

In this paper we present a modeling approach to a system for renewable energy generating including the loss of all the generation chain. The choice of the energy generation chain components is conducted taking account of the possibility to achieve high current to recover high power in the one hand and the simplicity of the chain structure and of its components in order to reduce the cost of production in the other hand. Indeed, a synchronous motor wit coiled rotor and reduced production cost is chosen for the electric energy generation. To enable continuous energy recovery, excitation current is increased at low speeds and reduced at high speeds to prevent over current problem. The implementation of the global model in the simulation environment Matlab Simulink has led to very good results of simulations encouraging the industrialization process of this chain.

Methodology for optimal design and control of wind energy system based on simplifying assumptions

“…The each phase of the generator is equivalent to a resistor in series with an inductance and an induced electromotive force. The generator three phase’s model is described by the following equations (Buticchi et al, 2012; Hadj Kacem et al, 2013; Howlader et al, 2014; Kim et al, 2010; Natsheh et al, 2011; Tounsi, 2011, 2015, 2019; Tounsi and Abdallah, 2020):…”

“…Therefore, our choice fells on a synchronous structure with wound rotor and axial flow as an electric generator. In order to determine the geometric and electrical characteristics of the generator, an analytical sizing program is developed (Buticchi et al, 2012;Hadj Kacem et al, 2013;Howlader et al, 2014;Kim et al, 2010;Natsheh et al, 2011;Neji et al, 2006;Nouha and Tounsi, 2017;Tounsi, 2011Tounsi, , 2015Tounsi, , 2019Tounsi and Abdallah, 2020).…”

“…The motion equation is expressed by the following equation (Buticchi et al, 2012;Deshpane, 2015;Hadj Kacem et al, 2013;Howlader et al, 2014;Kim et al, 2010;Natsheh et al, 2011;Neji et al, 2006;Nouha and Tounsi, 2017;Shin et al, 2013;Singh et al, 2019bSingh et al, , 2019cTounsi, 2011Tounsi, , 2015Tounsi, , 2019Tounsi and Abdallah, 2020;Yazdanpanah and Mirsalim, 2014):…”

Analytical design and control of switching synchronous motor

“…The coils are with concentrated type, which makes it possible to reduce the space occupied by the motor due to the small space occupied by the coil heads. The rotor teeth are also straight, which leads to a reduction in the production cost of this type of motor …”

“…Indeed, the engine is designed by the FEMM finite element software according to the data provided by the analytical program. The mesh is refined to have a good accuracy on the results …”
