US Patent:

40193152, Apr 26, 1977

Filed:

Jun 20, 1973

Appl. No.:

5/371623

Inventors:

Robert A. Yannone - Aldan PA
James J. Shields - Philadelphia PA

Assignee:

Westinghouse Electric Corporation - Pittsburgh PA

International Classification:

F02C 910

US Classification:

60 3903

Abstract:

A gas turbine power plant is provided with an industrial gas turbine which drives a generator coupled to a power system through a breaker. The turbine-generator plant is operated by a hybrid control system having digital function capability during sequenced startup, synchronizing, load buildup and steady state load, and shutdown operations. The control system also contains monitoring and protective subsystems which function through all stages of operation, with redundancy and permissive features which maximize turbine availability.

Nov 16, 1979

Appl. No.:

6/095174

Inventors:

Robert A. Yannone - Aldan PA

Assignee:

Westinghouse Electric Corp. - Pittsburgh PA

International Classification:

F02C 726

US Classification:

60 39141

Abstract:

A gas turbine power plant is provided with an industrial gas turbine which drives a rotating brushless exciter generator coupled to a power system through a breaker. One or more of the turbine-generator plants are operated by a hybrid digital computer control system during sequenced startup, synchronizing, load, and shutdown operations. The program system for the computer and external analog circuitry operate in a multiple gas turbine control loop arrangement. Logic macro instructions are employed in programming the computer for logic operations of the control system.

Appl. No.:

8/557844

Inventors:

George Heinz Quentin - San Jose CA
Robert Alfred Yannone - Lansdowne PA

Assignee:

Electric Power Research Institute, Inc. - Palo Alto CA

International Classification:

G06F 1100
G01M 1900

US Classification:

36455101

Abstract:

An apparatus and method to assess the performance of a start of a turbine is described. The apparatus includes an accumulator to compare a set of on-line data signals corresponding to the starting performance of the turbine to a set of normative starting parameters so as to identify a set of comparison signals. The comparison signals may also be identified by comparing the set of on-line data signals with a database of historical information relating to starts and design profiles of the turbine. In addition, the comparison signals may be identified by comparing the set of on-line data signals with information in an expert system defining fault conditions in previous starts of the turbine. The comparison signals are processed by an analyzer to identify those comparison signals that exceed predetermined thresholds. Those comparison signals that exceed the predetermined thresholds are processed by a risk factor assessor, which generates quality-of-start predication signals corresponding to the likelihood of success of future starts of the turbine.

Inventors:

John F. Reuther - Penn Hills Township, Allegheny County PA
Stephen J. Jennings - Radnor Township, Delaware County PA
Robert A. Yannone - Aldan PA

Assignee:

Westinghouse Electric Corp. - Pittsburgh PA

International Classification:

H02J 308
H02P 904

US Classification:

290 40C

Abstract:

Two gas turbine power plants are started and accelerated by fuel controls on selection of dead load mode. The startup is coordinated so that one turbine-generator is controlled as the lead unit and it is driven to a speed higher than normal, short of overspeed condition at which time its breaker is closed on an auxiliary bus. Shortly thereafter the second turbine-generator is synchronized to the first and its generator breaker is closed to the auxiliary bus. The two units are then ready for a simultaneous 200% load pickup from the dead load bus. After the load is applied, the lead unit is placed under isochronous control and the follow unit is tracked to the lead unit. Turbine lead/follow roles can be reversed during startup under certain conditions, and predetermined data is exchanged between the controls to enable coordinated dead load pickup operation.
