A hydraulic system is provided including, at least one hydraulic actuator, a distribution means in fluid communication with the at least one hydraulic actuator for selectively distributing hydraulic fluid to and from the at least one hydraulic actuator, at least one source of hydraulic fluid in fluid communication with the distribution means for supplying hydraulic fluid to the at least one hydraulic actuator, or for draining away hydraulic fluid from the at least one hydraulic actuator, a control means communicating with the at least one source for controlling pressurizing of the hydraulic fluid into the at least one actuator, or the draining away of the hydraulic fluid from the at least one actuator. Further, a pitch control system for a wind turbine and a method for operating a hydraulic system are also provided. |
