Abstract:
Conventional energy systems are very costly and have very adverse effect on the environment. Renewable energy resources are very concerned in these day. These systems are should be cost effective and reliable. Wind turbines systems already exist, but by increasing energy demands, we need to make the system much efficient. Conventionally wind turbine systems design for constant speed, that can capture energy on constant speed wind otherwise disconnected. There is need highly controllable and efficient wind turbine system with variable speed wind, which will be able to capture energy at every wind speed. Along with the circuit designing, there are a lot of issues concerned with generators being used. Many types of losses are present in gear box generators used in the earlier systems. Directly grid connected generators are proposed for the operation of variable wind energy system. A complete system is being analyzed and design for the variable speed of the wind. Before practical implementation of variable speed wind turbine system in field. A complete model designing according the required parameters is necessary. We purposed and design a variable speed wind turbine emulator, able to measure parameters very close to the field scenario. It’s provide complete design parameters for real system designing and testing. A resistive load is being attached at the output to measure the current, voltages and power changing with the speed of the wind. MATLAB sim power system is used for simulation of the whole system before the practical design of the system. Although for detail analysis of current, voltages and power waveform, graphs tools have been used in MATLAB by taking continuous data from the output.
