Control for Reheat Steam Temperature of Power Plant Based on Particle Swarm Optimization

Abstract

The model of reheat steam temperature of power plant has characteristics such as large delay and large inertia, the traditional PID control is difficult to achieve good results. his paper presents a new PSO with random acceleration factors and verifies its validation , also, this paper presents a new control method, uses the modified PSO to identify the model, tunes parameters SIMTH-PID control based on particle swarm optimization and the results of identification. The simulation results show that the method is more effective than the traditional PID control. KeyWords-Particle swarm optimization, Reheat steam temperature, Identification
