Wind-diesel Hybrid Power Systems combine diesel generators and wind turbines,in conjunction with equipment such as energy storage, power converters, and various control components, to generate electricity. esigned to increase capacity and reduce the cost and environmental impact of electricity generation., and reduce reliance on diesel fuel.
Technology
The system relies on complex controls to ensure correct sharing of intermittent wind energy and controllable diesel generation. Wind Penetration , the ratio between Wind Power and Total Power delivered is the measure of performance of these systems. controlling wind output using variable speed Wind Turbines are solutions for th eproblem of variable wind speed.
Wind“Diesel Generation Using Doubly Fed
Induction Machines
VARIABLE-SPEED operation of wind turbines has many
advantages. The torque extremes in the gearbox and shafts are reduced,
the power fluctuations can be absorbed as an inertial
energy in the blades and the wind turbine can operate with maximum aerodynamic efficiency,
the wind turbinemay
be augmented by an additional source, usually a diesel generator.
which are called
wind“diesel systems
diesel engines have high fuel consumption
when operating at light load and constant speed. for light loads at rated speed operation, not all the fuel
is burned by the engine causing wetstacking. variable-speed
diesel engines can increase efficiency and reduced fuel consumption by up to 40%,. Moreover, the engine life is increased because the diesel engine
is run at a low speed for a light load.
