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.

摘要： PURPOSE:To perform highly sensible fuel breakage detection by comparing the normal-time noise signal component contained in the detect signal of a delayed neutron detector provided at the coolant inlet, etc., of an intermediate heat exchanger with the detect signal from which the noise signal component is removed based on the estimation made from an autoregressive model. CONSTITUTION:Analog signals detected by a delayed neutron detector 1a are inputted to an A/D converter 3a and the furnace output of a fast reactor are detected by an output meter 1b and inputted to an autoregressive model implementing section 5 after the output is converted by an A/D converter 3b. The section 5 implements an autoregressive model from the successively inputted normal-time signals of the detector 1a, furnace output signals, and a prescribed formula and preserves the implemented model in a memory 6. At a background component removing section 7 the signal inferred from the autoregressive model is removed from the signals from the detector 1a and a reside signal is obtained. When the residue signal exceeds a threshold value, a broken fuel detecting section 8 decides that a broken fuel exists and inputs the decided result to a operation controlling rod selecting section 9.

摘要： PURPOSE:To enhance the efficiency of works such as various designs, analyses and diagnoses, etc., by selectively combining desirable transfer function from various transfer functions expressed in module on a color graphic display. CONSTITUTION:By linking a block which shows a function with a line which shows a signal on a CRT so as to draw a block chart in a system which should be simulated, a user obtains model frame data generated by inputting an input/ output signal, a parameter and an initial value of function unit. After a function computation is executed supposing t=0 and n=0 (n is the number of function), the operation is repeated until n>module is obtained. Next, in order to obtain time series data it is repeated until t>tmax is completed after setting t=t+DELTAt. And dynamic characteristic simulation is completed by outputting it on the CRT. Even if the system which should by simulated alters and the function to be used and its order alter, it is not necessary to change a program, itself, just with changing the block chart on the CRT, so that the efficiency in works such as dynamic characteristic analyses, etc., can be enhanced.

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 support the condition judgement of an operator by executing only a diagnostic means when a warning is not generated in the case that abnormality is detected, executing both the diagnostic means and a warning processing means when the warning is generated and displaying both results of these means. CONSTITUTION:When the warning is generated, as the output of a warning processing diagnostic part 4, a first generation warning and most important warning, which inquires most attention to the operator, are obtained. When data exist to be coincident with a reference pattern in a reference pattern data base 11, a cause why the first generation warning is generated or additional information to be obtained when the operator experienced such a condition in the past, for example, the name of the warning narrowed down out of the candidates of plural first generation warnings, etc., are obtained as referring data. When the warning is generated, a guide selection part 5 selects a countermeasure to the most important warning out of an operation guide data base 9 and when the event of the abnormality cause is cleared, an operation guide is selected to the event of which a number is designated in the reference pattern data base 11. Besides the operation guide, the detailed diagnostic result and a diagnostic reason are displayed by an output display part 6. Thus, the condition judgement of the operator can be supported.
