view source
US Patent:

7315769, Jan 1, 2008
Filed:

Oct 31, 2005
Appl. No.:

11/263420
Inventors:

Chellappa Balan - Niskayuna NY, US
Sumit Bose - Niskayuna NY, US
Zhihong Ye - Austin TX, US
Jovan Bebic - Clifton Park NY, US
Juan de Bedout - West Glenville NY, US
Yan Liu - Ballston Lake NY, US
Luis Garces - Niskayuna NY, US
Assignee:

General Electric Company - Niskayuna NY
International Classification:

G05D 17/00
H02J 3/38
US Classification:

700286, 700291
Abstract:

A plurality of power generating assets are connected to a power grid. The grid may, if desired, be a local grid or a utility grid. The power grid is connected to a plurality of loads. The loads may, if desired, be controllable and non-controllable. Distribution of the power to the loads is via a controller that has a program stored therein that optimizes the controllable loads and the power generating assets. The optimization process is via multi-tier benefit construct.

US Patent:

7358710, Apr 15, 2008
Filed:

Apr 18, 2006
Appl. No.:

11/406487
Inventors:

Shiguo Luo - Austin TX, US
Zhihong Ye - Austin TX, US
Guangyong Zhu - Austin TX, US
Assignee:

Dell Products L.P. - Round Rock TX
International Classification:

G05F 1/40
US Classification:

323282, 323272, 323277
Abstract:

A resister network having a negative temperature coefficient (NTC) may be utilized to create a temperature compensated equivalent resistance “R” for a current sensing RC network used in measuring inductor current of a DC-to-DC converter or a general switching regulator that needs to use inductor current as a control signal. The NTC resistor of the RC network effectively compensates for the positive temperature coefficient of the switching regulator inductor's inherent DC resistance (DCR). Keeping the time constants of the RC network and the switching regulator inductor substantially matched improves operation of cycle by cycle based control modes such as peak current sensing by the switching regulator controller in performing peak current control for the DC-to-DC converter.

11/392166
Inventors:

Robert Delmerico - Clifton Park NY, US
Mark Cardinal - Altamont NY, US
Nicholas Miller - Delmar NY, US
Dapeng Liu - Shanghai, CN
Zhihong Ye - Austin TX, US
Assignee:

General Electric Company - Schenectady NY
International Classification:

G05D 11/00
US Classification:

700291
Abstract:

A system, a method, and an article of manufacture for controlling operation of an electrical power generation system are provided. The electrical power generation system has a plurality of electrical generators electrically coupled to an electrical grid. The method includes obtaining a first output parameter value associated with the electrical power generation system. The method further includes determining an error value indicative of a difference between the first output parameter value and a desired output parameter value. The method further includes determining a first gain value based on at least one of the first output parameter value and a time-varying operational parameter of the electrical power generation system. The method further includes determining a first power value based on the error value and the first gain value. The method further includes determining a second gain value based on at least one of the first output parameter value, the time-varying operational parameter, and a reference value.
