The selection about the layout of turbines based on the following criteria:The power output of wind turbine with wind potential placement fact bring power-play performance.The performance of shielding between the wind farm turbines > 90%Ensure cost saving electrical connection (distance of larger turbines, the electrical connections as expensive)According to the experience of the projects were implemented in Vietnam and in the world, the distance between the rows of blades in the direction perpendicular to the wind direction is 4 d + 5 d. With the geographic location of the project, after considering the 22kV grid connection capacity internally, if increasing the distance between the blades in the same row will lead to 22kV cables line length increases dramatically causing voltage and cost more but the performance and power output did not increase much. The distance between the rows of the turbine is the 7 d will ensure the wind farm layout efficiency ≥ 90%.So, the options that the average distance between the layout of the turbine in the same rows perpendicular to the wind direction is 4 d-5 d and between rows is turbine 7 d is the option chosen to calculate power output.
