Abstract
Systems and methods for use in controlling a hydraulically powered AC generator are provided. One control system includes a valve system. The valve system includes a fixed valve configured to provide a substantially constant flow rate of the fluid through the fixed valve to the hydraulically powered AC generator. The valve system further includes a variable valve configured to provide a variable flow rate of the fluid through the variable valve to the hydraulically powered AC generator. The control system further includes a sensor device configured to measure a speed of movement of a component of the hydraulically powered AC generator. The control system further includes a control circuit configured to control the variable flow rate of the variable valve based on the speed of movement of the component measured by the sensor device.
