Analysis of Calculation Methods to Evaluate Losses and Efficiency of Wind Generators

In this Paper Analysis of Calculation Methods to calculate the losses and output power of wind turbine generator systems with using two types first one is Squirrel-Cage Induction Generator and the second is Doubly-fed Induction Generator. By using the existing methods in this paper, we can evaluate the generated output power, total system losses, total energy generated, efficiency and capacity factor of wind turbine generator. The techniques presented in this paper wind speed as the input and then all state variables and conditions of the wind generator system, for instance wind turbine power, generator output power, grid input power from the system and various losses in grid interconnected. Most of the countries are coming to this adopt this energy sources because the Wind energy is a clean and renewable energy source in the world and most essential the viewpoints of global warming and reduction the fossil fuels. In adding the wind turbine generator system (WTGS) is very low cost in compare with other systems renewable energy sources. But the power achieved from wind generator (WG) is not continues constant due to wind speed variations in different area of the world. The generated electric power and the loss in wind turbine generator system (WTGS) change analogous w.r.t wind speed variations and so the efficiency and the capacity factor of the system are also changed. But we can analyze the optimal WTGS of different area of the world because the optimal WTGS annual energy production and capacity factor are very important factors.
