Abstract

System used for aiding the operation of processes occurring in a power generation plant is disclosed which includes a logging technique for transforming input data from various pickup points into a universal, named system variable format usable by all system functions. Specified changes in time or in any system variable can cause a given log to be triggered into a storing state, or an outputting state wherein the stored data is outputted by a printer in a page oriented log print-out format. Also included in the system is a sequence of events interrupt technique wherein the detection devices located within the protective circuits are corrected for their respective time delays between the sensing time of a measured condition and the actuation time of the associated switching contacts. The correction is achieved by storing the predetermined values of the time delays associated with each of the detection devices, and subtracting such stored time delay values from the system detected times of actuation of the respective switching contacts, thereby deriving a corrected sequence of events indicating the correct order of occurrence of the events at the detection devices and, consequently, the initial cause of the event. The system also includes an alarming technique wherein alarm limit values are assigned for a measured system variable at a given point in the system, and realarm values are calculated so that realarming occurs when the measured system variable departs from the last alarmed value by a significant amount of change, thereby employing system discretion in selecting only the most important alarm conditions to be outputted. A CRT device is used for displaying the alarm information and operates with a reduced line format for those alarms acknowledged by the operator. Entry, removal and presentation of alarm data on the CRT screen is designed to present the data in a simple and easily understandable manner while maximizing the amount of data presented.
