  • One embodiment of the invention includes a system for operating a railway network comprising a first railway vehicle (400) during a trip along track segments (401/412/420). The system comprises a first element (65) for determining travel parameters of the first railway vehicle (400), a second element (65) for determining travel parameters of a second railway vehicle (418) relative to the track segments to be traversed by the first vehicle during the trip, a processor (62) for receiving information from the first (65) and the second (65) elements and for determining a relationship between occupation of a track segment (401/412/420) bymore » the second vehicle (418) and later occupation of the same track segment by the first vehicle (400) and an algorithm embodied within the processor (62) having access to the information to create a trip plan that determines a speed trajectory for the first vehicle (400), wherein the speed trajectory is responsive to the relationship and further in accordance with one or more operational criteria for the first vehicle (400).« less

  • A system and method for complete on-line testing of the emergency trip system of a turbine power plant is disclosed. The mechanical trip valve and a portion of a line to drain, of the emergency trip system, are isolated from the remaining portions. The testing of the valve is permitted without an opening to drain the line, which would cause a turbine trip. A three-way solenoid valve obstructs the line to isolate an upstream portion from a downstream portion while permitting introduction of fluid into the downstream portion at a pressure distinct from that in the isolated upstream portion. Pressuremore » sensitive switches, which operate suitable indications are provided in fluid communication with both portions of the line to drain to sense the differential pressure therebetween upon operation of the solenoid valve and, subsequently, a rapid diminishing of pressure in the downstream portion indicative of a successful test of the mechanical trip valve.« less
  • This patent describes a steam turbine power plant. It comprises: a steam generator; a steam turbine adapted to receive steam form the steam generator; a throttle valve for regulating the flow of the steam received by the steam turbine; and an electro-hydraulic trip control system for causing the throttle valve to close when a predetermined condition has been reached.
  • The present invention provides methods for preventing low train voltages and managing interference, thereby improving the efficiency, reliability, and passenger comfort associated with commuter trains. An algorithm implementing neural network technology is used to predict low voltages before they occur. Once voltages are predicted, then multiple trains can be controlled to prevent low voltage events. Further, algorithms for managing inference are presented in the present invention. Different types of interference problems are addressed in the present invention such as "Interference During Acceleration", "Interference Near Station Stops", and "Interference During Delay Recovery." Managing such interference avoids unnecessary brake/acceleration cycles during acceleration,more » immediately before station stops, and after substantial delays. Algorithms are demonstrated to avoid oscillatory brake/acceleration cycles due to interference and to smooth the trajectories of closely following trains. This is achieved by maintaining sufficient following distances to avoid unnecessary braking/accelerating. These methods generate smooth train trajectories, making for a more comfortable ride, and improve train motor reliability by avoiding unnecessary mode-changes between propulsion and braking. These algorithms can also have a favorable impact on traction power system requirements and energy consumption.« less
