Abstract: (124 Views) |
Power system design and controls are done with stability and reliability. Frequency is one of the important variables to stabilize the speed of engine loads. Considering the vital role of gas turbines in producing electricity without harmful effects on the environment, in this paper, utilizing the Rowen model for the frequency power system, the load-frequency control with the secondary control loop has been examined. For this reason, the design is done by the transfer function and state space. To begin with, the conventional PID controller is designed utilizing CHR and CC calculations in order to increase the system speed, eliminate disturbance and reduce the sum of overshoot. At that point, LQR linear optimal controller is utilized. Finally, due to the uncertainty and disturbance, H2/H∞ robust controller has been considered with the three conditions of nominal performance, robust stability, and reduction of disturbance. The simulation results obtained with/without the presence of disturbance have been checked and compared in MATLAB software. The results of the simulations show the success of the proposed H2/H∞ robust control strategy in terms of convergence rate and fluctuation range among all the control strategies examined. |
