A SYSTEM FOR MANUALLY OR AUTOMATICALLY TRANSFERRING CONTROL BETWEEN COMPUTERS WITHOUT POWER GENERATION DISTURBANCE IN AN ELECTRIC POWER PLANT OR STEAM TURBINE OPERATED BY A MULTIPLE COMPUTER CONTROL SYSTEM ABSTRACT OF THE DISCLOSURE An electric power plant including a steam gener- ator and a steam turbine is operated by a control system including two redundant digital computers. Switching cir- cuitry is provided for coupling one of the computers through interface equipment to the steam generator and the turbine and a generator according to programmed 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 process. Tracking is produced by a system which includes the data link as well as tracking controls in the noncontrolling computer. Such tracking controls func- tion in the tracking mode of the noncontrolling computer to conform the control outputs of the two computers with little or no offset. On the execution of a computer transfer, the tracking controls are bumplessly switched out of opera- tion as the computer coming into control switches from the tracking mode to the control mode.
