Definitions

  • the electric power plant including a steam generator and a steam turbine is operated by a control system including two redundant digital computers.
  • Switching circuitry is provided for coupling one of the comput ers through interface equipment to the steam genera tor and the turbine and a generator according to pro grammed computer control.
  • a data link is established between the computers to transfer manual/automatic status and other needed data from the control computer to the standby computer.
  • a system is provided for detecting when certain hardware and software malfunctions have occurred and for responsively transferring control to the standby computer.
  • the standby computer is tracked to the control computer so that Control computer transfer can be made reliably without disturbing the electric power generation pro cess.
  • Manual backup controls are provided for the steam generator and the steam turbine and the system is organized to transfer particular or all control loops to manual operation manually under operator selection or automatically in response to the existence of certain conditions. The capability for transfer to man ual control is interfaced with the computer transfer system.
