Abstract:
A wind park comprising a plurality of wind turbines that are coupled to each other via a control network. Control data, for example, data derived from sensors may be exchanged between the wind turbines via the control network, thereby allowing the wind turbines of the wind park to adjust operational parameters based on data received from other wind turbines of the wind park.
Abstract:
A system and method for generating energy from tuning the natural frequency of masses relative to a ground plane and an external force. In some embodiments the external force is the action of the waves. The system has a first mass movable relative to the ground plane, wherein the external force induces an oscillation in the first mass relative to the ground plane. A second movable mass is carried by and movable relative to the first movable mass. The second movable mass creates kinetic energy as the result of varying the position of the second movable mass relative to the first mass. The system adjusts or tunes the frequency -of various components in relation to the natural frequency of the waves. The energy created by the relative motion can be converted to various forms of energy including electrical energy.
Abstract:
A control system (24) is provided for use with a plurality of generator sets (14). The control system may have a transmission network (16) connected to a load (12) and separately connectable to each of the plurality of generator sets. The control system may also have a selection module (28) configured to receive from a user a selection of available parameters for use as criteria in determining connections of the plurality of generator sets with the transmission network, and a controller (26) in communication with the plurality of generator sets and the selection module. The controller may be configured to detect a change in the load, and determine a desired change in a connection device of at least one of the plurality of generator sets with the transmission network based on the change in the load. The controller may be further configured to selectively affect the desired change based on the selection.
Abstract:
The inventive protection arrangement of an electric power system comprises a relay arrangement (12)for measuring current, voltage or both of an electric grid(15). The relay arrangement is adapted to detect over-current, under-voltage or both. The protection arrangement comprises also a speed/load controller (16)that is in connection with the relay arrangement(12). The speed/load controller is arranged to drive a prime mover(11)of a generator(10)set as a response for the said detection. The speed/load controller(16) is connectable with said prime mover(11). In more detail the controller(16)is arranged to drive power output of the prime mover(11) to a lower level when over-current, under-voltage or both is detected.
Abstract:
A generator set includes an internal combustion engine and a generator driven by the engine. The generator provides electricity to a plurality of loads, each of which is selectively connected to the generator by a switch. The generator set is controlled by a method that includes receiving a command to connect a given load to the generator. In response to that command, a throttle of the engine is changed to a transition throttle position and an transition excitation voltage is applied to the generator. Then the switch is operated to connect the given load to the generator. Thereafter, in response to a defined event occurring, the throttle is changed to a normal position and a normal excitation voltage is applied to the generator.
Abstract:
A power generation system is disclosed. According to one embodiment, the power generation system comprises a road plate assembly, a rocker arm coupled to the road plate assembly. The rocker arm undergoes a swinging motion by a downward motion of the road plate assembly caused by a vehicle passing over the road plate assembly. An electro-mechanical generator coupled to the rocker arm produces electricity by the swinging motion of the rocker arm.
Abstract:
Systems and methods for monitoring wind turbine operation are disclosed. A method in accordance with one embodiment includes processing sensor data received from at least one strain gauge located on a wind turbine shaft, with a processor located on the wind turbine shaft. In particular embodiments, the method can further include providing power for the at least one strain gauge and the processor via a non-contact link between a first component located on the wind turbine shaft and second component off the wind turbine shaft. In further particular embodiments, the method can still further include receiving data from the processor corresponding to bending moments at the wind turbine shaft, and automatically identifying load remediation solutions for the wind turbine, based at least in part on the data received from the processor.
