Patent number: 8538611Abstract: A multi-level system for management of a railway system and its operational components in which the railway system has a first level configured to optimize an operation within the first level that includes first level operational parameters which define operational characteristics and data of the first level, and a second level configured to optimize an operation within the second level that includes second level operational parameters which define the operational characteristic and data of the second level. The first level provides the second level with the first level operational parameters, and the second level provides the first level with the second level operational parameters, such that optimizing the operation within the first level and optimizing the operation within the second level are each a function of optimizing a system optimization parameter. The levels can include a railroad infrastructure level, a track network level, a train level, a consist level and a locomotive level.Type: GrantFiled: December 15, 2003Date of Patent: September 17, 2013Assignee: General Electric CompanyInventors: Ajith K.

Patent number: 5517424Abstract: A method for automated control of a steam turbine during cyclic operation includes the steps of comparing current turbine loading with an anticipated load profile to generate a load error signal. Anticipated electrical load profiles correspond to the time of day, day of the week, month of the year, and historical data; operator input can vary such historical profiles as appropriate for unusual situations. The predicted load profile is categorized with respect to selected composite electrical load cycle profiles; weighted operating constraints are generated by means of a fuzzy inference calculation using electrical cycle profiles selected to correspond to the anticipated electrical load profile.Type: GrantFiled: March 31, 1994Date of Patent: May 14, 1996Assignee: Electric Power Research Institute, Inc.Inventors: Kenneth A.

Patent number: 5433079Abstract: A method for automated control of a steam turbine prewarming procedure employs fuzzy logic to generate a control signal for a turbine regulatory function, such as steam supply. The method includes the steps of determining a plurality of turbine condition parameter signals; generating a plurality of regulatory control directions; generating a weighting factor to be assigned to each of said regulatory control directions by means of a fuzzy inference calculation in accordance with an operator-selected fuzzy logic profile, and applying the weighting factors to the regulatory control directions to produce the turbine regulatory function control signal. The turbine regulatory function control signal is applied to a respective function controller in the steam plant such that the selected turbine prewarming profile is implemented.Type: GrantFiled: March 8, 1994Date of Patent: July 18, 1995Assignee: General Electric CompanyInventors: Vivek V.
