摘要： PROBLEM TO BE SOLVED: To appropriately confirm soundness when plant is renewed for increasing its output.
SOLUTION: At a place to be monitored extracted by a monitoring target extraction means 12 based on a renewal specification for increasing the output of the plant 11, a data measuring device 14 is attached, and the data, before the plant renewal, measured by its data measuring device 14 is stored in a database 15 for storing the data before the renewal 15. Based on the data stored in the database 15 for storing the data before the renewal, a monitoring criterion generation means 16 generates the monitoring criterion for determining abnormalities of the data measured after the renewal for increasing the output of the plant. Moreover, a monitoring means 18 compares a monitoring criterion 17, generated by the monitoring criterion generation means 16, with the data after the plant renewal measured by the data measuring device 14, and monitors if there are any abnormalities in the data.

摘要： PURPOSE:To intend identification of abnormality of plan equipments and observation apparatuses by representing the dynamic performance model of main plant system in the form of a block diagram with correspondence to actual observation signals, and by setting the calculation order and obtaining differences between a plurality of prediction models and the actual observation signals. CONSTITUTION:First of all, a system consisting of controllers, operating apparatuses, objects to be controlled and a group of detectors to detect conditions, is presumed. In the block diagram, operation can be done by following arrow marks in forward or reverse direction, and moreover information for judging whether observation of the output status value of each block is possible or not is also contained. By selecting a partial model being cut off from the block diagram and by determining calculation order of the block contained in the partial model, functions are called sequentially according to thus determined order, and calculation is carried out. Subsequently, a surveillance object signal for the whole system, is selected from observable signals, and moreover the partial model for predicting the serveillance object signal is searched. Then, calculation procedures of an initial value and a dynamic performance are decided, and finally abnormalities of both e1 and e2 are detected at a certain time decided by the model and therewith a detector G6 for common parts is judged to be abnormal from the constitution of both models.
