Abstract or Description

Due to the importance of micro turbine in Micro Grid Applications, this paper is proposed. Artificial Neural Network (ANN) model based on a state-space model of the micro turbine is developed which has fuel demand signal as input and torque and speed of the turbine governor and turbine exhaust temperature as the output. The developed model is tested too in MATLAB Simulink and the output of the turbine is measured and plotted. The turbine torque follows the changes in the load torque and produces the required demand torque. The turbine exhaust temperature has a similar characteristic as the turbine torque. Initially when there is an increase in the turbine torque, the temperature also increases and then settles down to steady state value less than the reference temperature. A micro turbine is used in conjunction with a generator in order to produce electrical energy. The generator model used here is a two-pole Permanent Magnet Synchronous Generator. The electrical and mechanical parts are represented by a second order state space model. The purpose of this model is to analyze and simulate the behavior at different operating conditions. Then, ANN technique is used to extend the range of loads with making benefits from its ability of predictions based on the data extracted from the state-space model. We propose general modeling and simulation at more probable situations for variable values. The simulation results at each case are well depicted in 3-D figures. Finally, algebraic equations for the ANN model are deduced. This neural network unit is implemented, using the back propagation (BP) learning algorithm due to its benefits to have the ability to predict values in – between learning values, also make interpolation between learning curves data. This is done with suitable number of network layers and neurons at minimum error, excellent regression constant and precise manner.
