Method, System And Storage Medium For Determining A Vehicle Reference Speed

View page
US Patent:
6758087, Jul 6, 2004
Filed:
Apr 26, 2001
Appl. No.:
09/842554
Inventors:
Edgar T. Balch - Erie PA
Ajith Kuttanair Kumar - Erie PA
Bret Dwayne Worden - Union City PA
Assignee:
General Electric Company - Schenectady NY
International Classification:
B61C 1508
US Classification:
731181, 73488, 180197
Abstract:
An exemplary embodiment of the invention is a method for determining a reference speed approximating a ground speed of a vehicle having a plurality of axles. The method includes selecting a minimum vehicle speed based on one of the axles having a minimum speed. An axle having a lowest amount of creep is determined and designated as a speed axle. A derived speed from the speed axle is obtained and compensated by subtracting a creep value from the derived speed to obtain a corrected speed. Operating dynamics for the vehicle are determined and a reference speed is determined based on the minimum vehicle speed or the corrected speed in response to the operating dynamics.

Locomotive Wheelslip Control System

Assignee:
General Electric Company - Erie PA
International Classification:
B61C 1508
US Classification:
318 52
Abstract:
A locomotive propulsion system includes wheelslip control with the following interrelated features: comparing the rotational speeds of the locomotive's separately driven wheels and detecting the highest and lowest; providing a reference speed value indicative of the rotational speed of a wheel that is not slipping; determining a desired maximum difference between the reference speed and a selected one of the detected speeds; deriving a speed error value by summing the reference speed, selected speed, and maximum difference; obtaining a wheelslip correction value which is a function of the speed error value; reducing the magnitude of voltage applied to the locomotive's traction motors in accordance with the correction value.

Automatic Flashover Protection For Locomotive Traction Motors

View page
US Patent:
51684160, Dec 1, 1992
Filed:
Sep 18, 1990
Appl. No.:
7/584566
Inventors:
Ronald B. Bailey - Erie PA
Herbert J. Brown - Erie PA
Myron L. Smith - Fairview PA
Edgar T. Balch - Erie PA
Roger D. Huczko - Erie PA
Joseph A. Laukaitis - Erie PA
Assignee:
General Electric Company - Erie PA
International Classification:
H02H 708
US Classification:
361 31
Abstract:
Flashover protection is provided for a locomotive propulsion system including a plurality of d-c traction motors each having a commutator subject to flashovers, a traction alternator having armature and field windings and a rotor driven by a prime mover, a controllable source of excitation current connected to the alternator field, and means including an electric power rectifier for connecting the alternator to the motor commutators. It comprises means for producing a fault signal whenever a flashover occurs in any motor, a solid-state controllable electric valve connected between the excitation current source and the alternator field and having alternative conducting and non-conducting states, and means for changing the valve from conducting to non-conducting states in response to a fault signal being produced, whereupon the magnitude of excitation current in the alternator field is rapidly reduced toward zero and the alternator's output current is correspondingly decreased whenever a flashover occurs.

Torque Maximization And Vibration Control For Ac Locomotives

View page
US Patent:
58412549, Nov 24, 1998
Filed:
Jul 9, 1997
Appl. No.:
8/890220
Inventors:
Edgar Thomas Balch - Erie PA
Ajith Kuttannair Kumar - Erie PA
Luzern Arthur Richter - North East PA
Sean Erin Gleason - Indianapolis IN
Assignee:
General Electric Company - Erie PA
International Classification:
B60K 100
B61C 1508
US Classification:
318430
Abstract:
A traction control system for an ac locomotive optimizes traction performance by separately controlling the allowable creep level of each individual axle and by minimizing torsional vibration per axle. The traction control system includes a torque maximizer and a torsional vibration detector. The torque maximizer measures traction system performance levels and determines the desired torque maximizer state for maximizing traction performance of each individual axle. The torsional vibration detector digitally processes estimated torque feedback of each traction motor in order to detect an unacceptable level of torsional vibration. The outputs of the torque maximizer and the torsional vibration detector are provided to a creep modulator which processes these inputs in order to control the operating creep level of each locomotive axle. As a result, traction performance is improved while minimizing torsional vibration and operating noise levels due to wheel/rail squeal.

Traction Vehicle Adhesion Control System Without Ground Speed Measurement

US Patent:
62080970, Mar 27, 2001
Filed:
Dec 6, 1999
Appl. No.:
9/455431
Inventors:
Suresh Baddam Reddy - Erie PA
Jeffrey Louis Diagle - North East PA
Bret Dwayne Worden - Union City PA
Harry Kirk Mathews - Clifton Park NY
Edgar Thomas Balch - Erie PA
Allan John Connolly - Albany NY
Ajith K. Kumar - Erie PA
Assignee:
General Electric Company - Schenectady NY
International Classification:
H02P15/08
US Classification:
318 52
Abstract:
An adhesion control system for a locomotive is provided for achieving and maintaining a maximum adhesion value. The adhesion control system includes a means for determining from an appropriate adhesion-creep curve an ideal creep rate that must be achieved and maintained in order to achieve and maintain a maximum adhesion value, a means for estimating an actual creep rate through the measurement or estimation of motor or wheel acceleration and locomotive acceleration, a means for selecting a creep rate set point based on a comparison of the actual creep rate and the ideal creep rate where the creep rate set point is set to a positive value if the actual creep rate is less than the ideal creep rate minus an acceptable differential and is set to a negative value if the actual creep rate is greater than the ideal creep rate plus the acceptable differential, and a means responsive to the creep rate set point for adjusting the operation of the locomotive so that the maximum adhesion value may be realized where the actual creep rate is increased if the creep rate set point is set to the positive value and is decreased if the creep rate set point is set to the negative value.

Load Rate Limiting Means For A Locomotive Engine

US Patent:
61631213, Dec 19, 2000
Filed:
Sep 24, 1999
Appl. No.:
9/405633
Inventors:
Ajith K. Kumar - Erie PA
Edgar T. Balch - Erie PA
Assignee:
General Electric Company - Schenectady NY
International Classification:
H02P 700
US Classification:
318434
Abstract:
A method and traction control system for an AC locomotive which separately controls the allowable creep level of each individual axle and optimizes traction performance by minimizing torsional vibration per axle. The traction control system includes a torque maximizer and a torsional vibration detector. The torque maximizer evaluates the change in traction system performance levels and actual creep level of individual axles and determines the desired torque maximizer state for maximizing traction performance of each individual axle. The torque maximizer utilizes digital filtering to minimize control cycle time. The torsional vibration detector digitally processes estimated torque feedback of each traction motor in order to detect an unacceptable level of torsional vibration. The outputs of the torque maximizer and the torsional vibration detector are provided to a creep modulator which processes these inputs in order to control the operating creep level of each locomotive axle. As a result, traction performance is improved while minimizing torsional vibration and operating noise levels due to wheel/rail squeal.
