Mini Hydro Plant, Dump Load, Servo Motor On-Off Control


In this paper, a new technique for load frequency control is adopted In general the frequency is controlled by using a dump load, whose rating is equal to the rated power output of the plant. The new scheme proposed reduces the size of the dump load by controlling input power of the hydro power plant using on/off controls. The water flowing through the penstock is rerouted in smaller pipes, two or three fitted with motor operated valves. The opening or closing of the valves is achieved by on/off controls. The on/off control linearly raises or lowers the generation. A transfer function model for the system is developed with an on/off control logic. Finally, system transient’s performance is compared for the case of two –pipe (50% dump load) and the three-pipe (30% dump load).
