US Classification:

73862324

Abstract:

The present invention provides a method and apparatus for applying a uniformly-distributed pattern of stripes () on a component () of a large rotary machinery, such as an industrial generator. A method is provided that comprises measuring the circumferential area of the component () with a measuring element (). The precise circumference is indicated and a desired number of pattern segments is determined. The circumference is divided by this number to produce equally spaced segments. This is then transferred to the rotor shaft () by marking on the measuring element () the number of segments and making a copy of the markings onto a second strip (). These strips are then aligned on the circumferential area and cross strips () are placed at each of the segment marks (). The segment areas not covered by the cross strips () are then painted in a color that is optically distinguishable from the non-painted regions. An optical probe () is then able to scan the stripes to detect torsional forces in the rotor shaft.

Abstract:

Apparatus for applying torsional vibration to a rotating machine is provided. In one exemplary embodiment the apparatus includes a permanent magnet machine () connected to the rotating machine () and configured to generate a three-phase AC output voltage. A converter () may be coupled to receive the three-phase AC output voltage from the permanent magnet machine to supply a DC load current. An electrical load () (or exciter) may be coupled to the converter to receive the load current. An oscillator () is connected to the converter to provide an oscillation signal for modulating the load current from the converter. Modulated load current causes variable loading of the permanent magnet machine thereby creating an oscillatory torque in the permanent magnet machine (). The oscillatory torque causes torsional vibration in the rotating machine. Various components of the apparatus for applying torsional vibration may be part of a field-deployed power generating system.

Inventors:

Joseph D. Hurley - Casselberry FL

Assignee:

Westinghouse Electric Corp. - Pittsburgh PA

International Classification:

F01K 1302

US Classification:

60646

Abstract:

A system is provided for independently testing trip valves in a multi-valve electro-hydraulic trip control system for a steam turbine. The electro-hydraulic trip control system features first and second channels arranged in series to control the pressure of a hydraulic fluid supplied to the actuator of the steam turbine throttle valve. Each of the channels has first and second trip valves arranged in parallel. First and second orifices are arranged in parallel with the first and second channels, respectively. First and second pressure switches are adapted to sense the pressure in the hydraulic fluid downstream of the first orifice. A programmable controller is programmed to test each of trip valves individually by individually opening and closing each of the trip valves sequentially and determining whether the signals from the pressure switches indicate that the trip valve being tested has opened. The programmable controller is programmed to indicate a valve failure should one of the trip valves fail to open.

US Classification:

296 70

Abstract:

An instrument panel brace for aiding in the alignment of the steering column of a vehicle during a collision. The brace is attached to the instrument panel beam which in turn is attached to the steering column. Further, the instrument panel brace lies adjacent the cowl rather than being rigidly attached to either the cowl or dash panel. During a collision, the brace resists rotation of the steering column caused when the driver's knees push up against the instrument panel beam while resisting transferring load from the engine to the steering column.

International Classification:

H02P 904

US Classification:

322 29

Abstract:

A synchronous condenser (12) is synchronized with a power system (14) by modifying its rotational speed using a prime mover (18) while controlling the rate of change of rotational speed of the synchronous condenser (FIG. 1). With an open circuit breaker (16), the synchronous condenser (12) is brought to a rotational speed (44) close to a desired synchronizing speed (48). A clutch (20) operates between the prime mover (18) and the synchronous condenser (12) and disengages the prime mover (18) from operation once the synchronous condenser (12) is placed into operation with the power system (14). An excitation voltage is provided to the synchronization condenser (12) for providing an output voltage, which voltage is monitored. The rotational speed of the prime mover (18) is ramped at a desirable rate of change (46) for approaching an acceptable synchronizing speed (50). The rotor speed and system phase angles are monitored for bringing a desirable changing speed close to the synchronizing speed (48).
