Abstract
Nowadays, electricity generating from wind energy increases from 112 MW in 2012 to 234 MW in 2015 and becoming more and more increasing. The investment in electricity generating from wind is costly compared to other types of renewable energy. Hence, an increase in the efficiency of electricity generating from wind is an alternative way to reduce rate of returns. This study investigates the setting of wind waiting direction of wind turbine by using method of huge error for data screening in order to be in the same database. Also, arithmetic mean of wind direction is used for setting wind waiting direction to reduce the time for the adjustment of the wind turbine face to the wind direction. Normally, it takes about 5 - 10 minutes, depending on the position of the wind turbine face before stops working. Results of the study can reduce the time for the adjustment of the wind turbine face. Also, it can increase the time for electricity generating of the wind turbine. Electricity generating in January to December, 2018 increases for 1,830 minutes (7,332 kWh) or 0.172 percent compared with data from SCADA system. Therefore, the proposed method can be used for setting wind waiting direction of the wind turbine to increase the efficiency in electricity generating.
