Double fed synchronous generator motor

Patent Number: 8111048
Publication Date: 2012-02-07
Inventors: Kenzaki, Akira; Machino, Takeshi

A double fed synchronous generator motor which is coupled to a reversible pump-turbine and operated while switched to a power generating operation mode or a pumping operation mode, is equipped with a controller for controlling the double fed synchronous generator motor so that power output from the double fed synchronous generator motor is coincident with an instruction value and the rotating speed is set between upper and lower limit values of the rotating speed by changing exciting ...

Generator set control system

Patent Number: 8106633
Publication Date: 2012-01-31
Inventors: Dozier, Chad Eric; Schroeder, Edward Maurer; Wagner, Matthew Lee

A control system is provided for use with a plurality of generator sets. The control system may have a bus, an arbitration relay, a switching device, a control module, and first, second, and third discrete signal cables. The control module may be configured to receive a group start signal and initiate startup of a first of the plurality of generator sets, and to generate a signal on the first discrete signal cable based on an operational status of the first of the plurality of generator ...

Optimal load controller method and device

Patent Number: 8098054
Publication Date: 2012-01-17
Inventor: Verschuur, John Alexander

A method and device for optimizing power output of a power generation system having a load engaging system, a load optimizing system, a load selection system, a motive driver and one or more loads or power transfer parameters. The power generation system is illustrated using an electrical generator to consume system power out, however the load(s) may be other than an electrical generator. The load engaging system decides when and how the load or power transfer parameters are applied to and ...
