Wind turbine on-grid systems convert wind energy into electricity and deliver it directly to the main power grid. These systems operate alongside traditional power infrastructure without requiring battery storage. They form the basis of commercial wind farms and are also used for residential and small-scale applications.
Primary Purpose
The main objectives are to reduce grid electricity consumption and sell surplus power to utility companies, lowering energy costs while contributing renewable energy to the grid.
Key elements include:
Wind Turbine: Consists of blades, rotor, nacelle, and tower. Captures wind energy and converts it to mechanical rotation.
Generator: Transforms mechanical energy into electrical energy. Common types:
DFIG: Enables variable speed operation
PMSG: Used in direct-drive designs
Power Converter: Critical component that ensures output matches grid specifications for voltage, frequency, and phase.
Transformer: Increases voltage to match grid requirements.
Control System: Monitors wind conditions and optimizes performance.
Protection Systems: Safely disconnects during grid disturbances.
Bi-directional Meter: Measures both consumption and export of electricity.
