Abstract :
Coal will play as a major fuel source for power production due to its long term availability. Hence it is necessary to develop clean and efficient coal gasification plants also known as greenhouse power plants. One of the main components in green house power plant is gasifier. The mathematical model developed by ALSTOM for gasifier is highly coupled multivariable system with transfer function of the order of 25. Handling such higher order transfer functions for controller design is found to be very difficult. It is necessary to have lower order transfer functions. This paper discusses the applicability of two methods namely Algebraic method and Reduced Order Approximations to get the reduced order transfer functions. The simulation results show that the algebraic method is more suitable than Reduced order approximation.
