| Summary: | The main aim of this paper is to provide
electric power generation using a renewable and portable method in rural and
geographically problematic areas where energy transmission is not possible.
Electric power generation from wind with low-cost, efficient and portable
small-scale wind turbine during natural disasters (earthquake, fire, flood,
etc.) leading to catastrophic consequences (long electrical black-outs) and for
individual low power applications is targeted. The control of gearless
Permanent Magnet Synchronous Generator (PMSG) along with load side inverter
control in this project are performed using a full-rating, bi-directional,
two-level, back-to-back voltage source rectifier/inverter with total of eight
switches for the variable speed wind turbine. Additionally, one of the major advantages
and novelty of using MRAS rotor flux linkage and stator resistance estimator in
this system is to correct changes in the flux and stator resistance values in
the control system. Due to its simplicity and effectiveness, the load side
control is achieved by using four switch grid side inverter. To observe the
total system performance, a three-phase passive load is used at the inverter
output. The low-pass LCL filter is designed and used in the load side to reduce
current and voltage harmonics and increase stability and efficiency of the
power network. The results of the overall system are validated with the
real-time DSP system. It is proved with this paper that the inclusion of a
simple, effective and economical position sensorless control in the generator
side show that renewable wind energy system can be a viable distributed green
energy solution for rural areas. |
