Abstract
Improvements introduced in an electrical power plant comprising at least one turbine; means for controlling the flow rate of the turbine drive fluid; a generator moved by turbine; and a control system, for controlling the operation of said power plant, comprising a first and second digital computers, means for generating input signals representing process variables associated with components (such as the turbine and/or a generator). Steam) of said power station, means for coupling said input signals to each of said computers, including each of said computers, control elements for generating control outputs as a function of said input signals, means for coupling the outputs control devices from each computer to controllable elements of said power station and place one of said computers with their corresponding control circuits in a condition to control said controllable elements and the other computer with its corresponding control circuits in reserve state, under conditions normal work, and detection means to detect malfunctions of the control system; according to which said control system comprises means for sensibly forming the structure of the computer in a state of reservation in real time with the predominant computer and conditioning the backup computer in such a way that the control outputs from the backup computer are substantially identical to those that come from the predominant computer; and means for executing a transfer in control of said controllable elements of the exchange from the predominant computer to the backup computer, in response to a malfunction of the control system detected by said receiving means.
