초록 ▼

An 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 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 function 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 operation as the computer coming into control switches from the tracking mode to the control mode.

대표청구항 ▼

A control system for an electric power plant having at least one steam turbine and a steam generator, said control system comprising multiple digital computers including at least a first digital computer and a second digital computer, means for generating input signals representing predetermined process variables associated with said steam generator, means for generating input signals representing predetermined process variables associated with said steam turbine, means for coupling the input signals to both of said computers, each of said computers having means for controlling its sequential programmed operation and including substantially identical control elements which generate control outputs as a function of input signals in various control loops to operate controllable elements of said steam generator and throttle and governor valves of said steam turbine, means for sensing predetermined control system malfunctions, means for coupling the outputs of one of said computers to operate the steam generator controllable elements and turbine valves, means for substantially conforming the structure of the other computer to the structure of said one computer in real time, said conforming means including means for responding to predetermined process input signals to control the operation of at least some of said computer control elements in a tracking mode and generate corresponding control outputs in said other computer substantially equal to those from said one computer, and means for executing a transfer in the control of the steam generator and the turbine from said one computer to said other computer substantially without disturbing the power generation when said sensing means detects a control system malfunction.
