Abstract
To overcome the shortcomings of standard Particle Swarm Optimization (PSO), for example, prone to lo-cal optimum and slow later convergence and so on , shrinkage factor and chaos idea were adopted to improve stand-ard PSO in the study .A novel design method for satisfactory function of hydro-turbine governing system was put for-ward.Chaos PSO was applied to parameters identification of controlled object for governing system .Quality parame-ters, such as rise time, settling time, hydro-turbine’ s reverse peak power and reverse peak time , were directly measured , and the overall satisfaction level of system was taken as fitness function .On the basis of the new method , the control parameters of a hydro-turbine governor were measured in association with parameter identification of hy-droelectric turbine-conduit system .Test results show that the simulated data correctly reflect the response character-istics of cascade frequency disturbance for the unit load , and meet the requirements of power grid stability calcula-tion.Furthermore, under large interference , the algorithm still has accurate parameter identification and high con-vergence efficiency .关键词
