<p><P>PROBLEM TO BE SOLVED: To provide an abnormality diagnostic device in a power generation system, capable of detecting an abnormality of a supercharger in the power generation system by a simple facility configuration. <P>SOLUTION: This abnormality diagnostic device sequentially reads pressure inside an intake manifold measured by a pressure measuring means as pressure data P(i) and sequentially reads power generation output of a power generator measured by a power generation output measuring means as power generation output data W(i). The abnormality diagnostic device calculates a variance value Pv related to the plurality of pressure data P(i) sequentially read for a predetermined calculation period T3 and a variance value Wv related to the plurality of power generation output data W(i) sequentially read for the predetermined calculation period T3, and detects the abnormality of the supercharger on the condition that the variance value Pv based on the pressure data P(i) becomes a predetermined pressure set value Ps or smaller and the variance value Wv based on the power generation output data W(i) becomes a predetermined power generation output set value Ws or smaller. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
