Homework SourseSimulate wind turbine with grid interface The system should
Simulate wind turbine with grid interface. The system should include fixed power factor operation scheme. Wind speed is an input, and the output should be interfaced with the 3 - phase grid.
Solution
Wind Energy Conversion Systems (WECS) have been attracting wide attention as a renewable energy source due to depleting fossil fuel reserves and environmental concerns as a direct consequence of using fossil fuel and nuclear energy sources. Wind energy, even though abundant, varies continually as wind speed changes throughout the day. The amount of power output from a WECS depends upon the accuracy with which the peak power points are tracked by the Maximum Power Point Tracking (MPPT) controller of the WECS control system irrespective of the type of generator used. This study provides a review of previous MPPT controllers used for extracting maximum power and the proposed method.
The Fig.1 shows the basic flow of wind power generation. Wind turbine power is used to convert kinetic energy into electrical energy through the use of a generator. As wind conditions vary, the electrical energy created from the generator needs to be converted for usability. A rectifier, inverter, transformer and filter are needed within the wind turbine for utility-grade AC power to be transmitted over long distances.
Wind energy can be harnessed by a wind energy conversion system, composed of wind turbine blades, an electric generator, a power electronic converter and the corresponding control system. The Fig.2 shows the block diagram of the basic components of WECS.
There are different WECS configurations based on using synchronous or asynchronous machines and stallregulated or pitch regulated systems. However, the functional objective of these systems is the same: converting the wind kinetic energy into electric power and injecting this electric power into a utility grid or to the load.
Simulation process was done in Matlab/ Labview tool by connecting all the blocks carefully.
