Prediction and Enhancement of Performance of Wind Farms in India

摘要

The paper reports the formulae for prediction of year round performance of wind farms based on experimental data for machines of capacities ranging from 20 to 1650 kW. The effect of machine size on the annual energy yield has been studied and shown that it is possible to develop performance prediction equations, which are independent of the size of the machine. These equations arc useful for a priori evaluation of wind turbine performance before their installation purely based on wind data. It is concluded that there is scope for improvement in the annual plant load factor by 1.0 to 3.0 percentage points by improving the grid and machine availability.
