Abstract: The present invention provides a method for enabling a large integrated monitoring screen for integrated monitoring of multiple reactors, and a large integrated monitoring screen system. The method for enabling the large integrated monitoring screen comprises the steps of: a screen generation managing device in a remote integrated monitoring center generating at least one of a status monitoring screen, an early warning screen, a diagnostic analysis screen, and a CCTV screen with respect to a plurality of reactors in a nuclear power plant; and transmitting a screen requested by an administrator to the large integrated monitoring screen through an integrated screen control device.

Abstract: The present invention provides a method for diagnosing a rotation device by means of a rotor-bearing-foundation model, the method characterized by utilizing the characteristics of a simulation rotor system. To this end, the present invention comprises the steps of: simulating a rotation device as a rotor system; forming a mathematical model for the rotor system; estimating the state of the rotation device by means of the mathematical model and a vibration measurement value of the rotation device; and diagnosing for abnormalities in the rotation device from the changes in an estimated value. Therefore, since a rotation device is diagnosed for abnormalities by means of forming a mathematical model for a rotor system, the present invention enables more accurate diagnosis of the rotation device.
