“…However, in the literatures, typically, have some inherent technical difficulties used in hydro applications, it is hard to balance the performances of stability, efficiency, and cost. The permanent magnet synchronous generator (PMSG) is an effective way to solve the above problems, and there are many scholars have focused on this solution [2, 10, 11].…”

Developing technology and growing population are increasing the need of countries for energy every passing day. Renewable energy resources, which are an environmentally friendly and local solution alternative to fossil fuels, are seen to be a significant source of supply in this matter. Among renewable energy resources, hydroelectric energy is in an advantageous position with its reliable potential and sustainable production. With the purpose of utilizing small flowing waters such as rivers and streams and solving problems of access to interconnected grids in rural areas, micro-type hydroelectric power plants have a significant potential for countries. This study carried out the design and performance analyses of permanent magnet synchronous generators (PMSGs) with different numbers of poles for micro hydroelectric power plants. The generators' flux density values and total voltage harmonic distortions were examined. Additionally, the cogging torque magnitudes have been analyzed. The generators were loaded with nominal loads, and the time-dependent waveforms of phase voltages were obtained. By subjecting the obtained voltages to Fourier analysis, their harmonic spectrum was created. Finally, by considering the amount of active material used for the designs, their costs were compared.Index Terms-Finite element analysis, Micro hydropower plant, Synchronous generator. I. INTRODUCTIONHE NEED for energy resources is increasing every day due to decreased fossil fuel resources, increased environmental concerns and population density. This has made energy supply one of the most important issues of today. Renewable energy resources (RER) are a significant solution for all these problems. The popularity of renewable energy is increasing as fossil fuels lead to environmental pollution and are being exhausted. In the period of 2000-2009, there were increases of 76% in oil prices, 114% in natural gas prices and 136% in coal prices. It is projected for the period of 2015-2040 that there will be increases of 186.3%, 85.7% and 56.3% in oil, natural gas, and coal prices, respectively. Considering the projections, it is important to increase renewable energy resources. Renewable energy is considered as inexpensive,
