| Abstract |
This paper proposes the sensorless optimum control method for the wind generation system, where an
interior permanent magnet synchronous generator (IPMSG) is used as a variable-speed generator. The
objective of this paper is to obtain the maximum generated output power from the wind energy and to
achieve such wind generation system without mechanical sensors. The maximum available wind
power can be obtained by the MPPT control without wind speed sensor, where the generator torque is
optimally controlled according to the generator speed based on the wind turbine model. The current
vector of IPMSG is optimally control according to the speed and torque command considering the
voltage and current constraints in order to make generator efficiency maximum and generate electrical
output power as large as possible. The speed and position sensors are not utilized in the IPMSG
control system, and such information is estimated based on the generator model. In order to verify the
effectiveness of the proposed wind generation system, several experimentations were carried out and
the performance of the proposed control method was discussed. |
