摘要: A dedicated supervisory control system for a steam turbine-generator comprising a hierarchy of microcomputer subsystems interactive with a conventional analog electrohydraulic control system to provide control and monitoring capabilities during all operating phases of the turbine-generator. The separate microcomputer subsystems are programmed for coordinated interaction and communication through shared, dual-port read/write memory units and each microcomputer subsystem is programmed and configured to handle a separate group of control responsibilities in a distributed control system. The microcomputer hierarchy includes an input and calculations computer having means for interfacing with analog input data sources and sensors which report on various operating parameters of the turbine-generator and from which thermal and mechanical stress and other derived quantities are calculated; a display and communications computer adapted to interface with a plant computer and with an operator control panel and other display and readout devices whereby operating personnel may interact with the control system; and a control computer, standing at the top of the hierarchy, for receiving information from the other computers, for making decisions based on that information and, through input/output ports, for providing the electrohydraulic control system with directions for optimal control of the turbine-generator within its thermal and mechanical limitations. The dedicated supervisory controller provides a plurality of operating modes.
