Abstract
Speed control is an important matter in a hydropower plant. Big hydropower plants perform frequency control of power system. Most of the governors of hydropower plants have used PID controllers. So they are less robust with parameter changes in operation and noise.
In this paper, we present a new method control to make a robust speed control of the hydropower in small grids using parameters of Srepok 3 hydropower plant, considering one unit with capacity of 110MW. The simulated research results show that the SMAC control adapts to noise and parameter change in the operation better than PID controller.
