Steady-state and transient comparative performance analysis of BLDC and PMSM generators for battery charging chains

Abstract

This paper provides a comprehensive analytical approach based on steady state and transient analysis of turbine power system using either a brushless DC generator or permanent magnet generator with Sinusoidal Waves-Form. The added value of this study is the use of a steady-state analytical model enabling the design and optimization of the power chain manufacturing parameters, given that the use of the steady-state analytical modeling technique is highly compatible with high-dimensional stochastic optimization algorithms. For the same turbine and generator stator structures, the energy recovered from the turbine with permanent magnet generator with Sinusoidal Waves-Form is compensating by an increase of the generator angular speed, since the electromagnetic torque acting as a brake is greater in the case of the brushless DC generator. The global model of the power chain is implemented under the Matlab-Simulink simulation environment. This model is validated against the classic model of the wind turbine using the SimPowerSystem library of power component models integrated under the Matlab-Simulink simulation environment.
