Due to the fine search process and strong global convergence of the artificial bee colony(ABC) algorithm, it is regularly taken in the parameter optimization of the hydraulic turbine regulating system(HTRS).However, the standard ABC algorithm still exist some problems such as slow convergence speed and low convergence ***, a chaotic and global ABC(cgabc) algorithm is proposed to overcoming these *** them, the global optimal is used to enhance the global exploration ability of the bee colony, and in order to increase the diversity of the population and help the bee colony to jump out of the local optimal solution, namely enhancing the local exploration ability of the population, the chaos optimization is *** integral for sum of the systematic error absolute value and system overshoot and the time product is taken as the fitness function of the algorithm, which is the performance evaluation index of the bee *** cgabc algorithm was used for simulation experiments of HTRS system when it is under different frequency and load disturbance *** results show that compared with ZN algorithm, fuzzy strategy, DE algorithm and ABC algorithm, the proposed cgabc algorithm significantly improves the dynamic transition process of HTRS system.
