Abstract
The objective of this research is to develop low-speed permanent magnet synchronous generators (PMSG) based on small-scale wind turbine application, low-speed operation, high performance and a small structure size. The results show that maximum power of generator is 1.5 kW, at a synchronous speed of 500 rpm with a frequency of 50.00 Hz and efficiency of 77.84%. The harmonic distortion of total harmonic voltage distortion limits (THDv%) and total harmonic current distortion limits (THDA%) at electrical load 6 A, indicated 1.7% and 1.9%, respectively. Therefore, this study shows the generators of wind turbine power plant give a high efficiency. Although high performance permanent-magnets have a high cost, but a few component the construction PMSG can be compensated in parts of generator. Thus, the PMSG have a low cost when a material will be fabricated in mass production
