【 摘 要 】

In this paper a power supply system based on a 10-kW wind turbine on-grid connected used for two different consumers is analysed. The proposed wind turbine site is located at coordinates 46°57'41"N 25°56'36" E, in the Ceahlau National Park, on the plateau of Ceahlau Mountain. Nearby there are located the two consumers: the Ceahlau Monastery and the Dochia Chalet. The site wind resource is obtained mainly from NASA Surface meteorology and Solar Energy database. The load demand curves, the annual energy consumption and the peak load are obtained considering the standard load profile for these two particular types of consumers. The on-grid power supply system is analysed using HOMER Energy microgrid modelling software for different tourist's occupancy. Two different wind turbines (XZ and XL) with rated power of 10 kW are comparatively analysed. Selection of the most suitable wind turbine is realized using the Weighted Product Method (WPM), for which nine attributes are used: annual energy production, capacity factor, renewable fraction, grid purchase, grid sales, initial investment, net present cost, levelized cost of energy, and simple payback. For a given criteria weights, the XL model is found to be the most suitable wind turbine.
