Frequency Excursion and Temperature control of Combined Cycle Gas Plant Including SMES

J. Raja, C. Christober Asir Rajan and Y. Thiagarajan

Abstract—This paper presents a MATLAB – SIMULINK based Dynamic model of a combined cycle stand alone gas power plant the transfer function model of load frequency and temperature control loop has been developed. The objective of this proposed work is to regulate the frequency and temperature in order to maintain the system stability of the power plant. Since most of the loads are induction type and the induction motor speed is directly proportional to frequency, the frequency has to be maintained within the limits. If temperature is low, it cause low efficiency of the heat recovery boiler and maintaining temperature higher than allowed will reduce life of the equipment. Hence the temperature has to be regulated to have safe operation of the power plant. Considering these backgrounds, it is important to study dynamic behavior of combined cycle plants. Hence it has been developed the dynamic model for a single shaft combined cycle plant. In this paper the analysis of power plant response to electrical load and frequency transients with the effects of SMES is presented.
