Energy Control System

EWP’s monitoring and control unit analyzes data received from the frequency converter on current consumption of electricity from the generator. If it is necessary to decrease or increase the intake of energy saved up in hydraulic accumulators, it sets the signal of flow control of working liquid for the pressure regulator and signal for the unit of hydraulic motor control , which using the actuating mechanism varies hydraulic motor parameters so that current consumption of working liquid and mechanical moment created by the hydraulic motor, i.e. power produced by the hydraulic motor, may correspond to consumed electrical power received from the generator. Such an adjustment mechanism will allow efficient consumption of energy accumulated in hydraulic accumulators.
