Abstract: There is provided a generator system monitoring apparatus for a generator system including a generator, a first measuring apparatus and a second measuring apparatus. A power-generation state determining unit determines whether the generator is generating the electric power or not. A measurement information acquiring unit acquires, when it is determined the generator is not generating the electric power, a first measurement value and a second measurement value from the generator system, the first measuring apparatus measuring electric power generated by the generator to obtain the first measurement value, and the second measuring apparatus measuring the electric power generated by the generator to obtain the second measurement value. A system state determining unit determines whether the first measuring apparatus has an abnormality or not by comparing the first measurement value and the second measurement value with each other.

Abstract: An acquiring unit acquires a first search criterion from outside. A first searching unit extracts a first search result that satisfies the first search criterion from a storing unit that stores information to be searched. A first output unit outputs the first search result to a first output device. A changing unit changes the first search criterion to a second search criterion based on a predetermined condition. A second searching unit extracts a second search result that satisfies the second search criterion from the storing unit. A second output unit outputs the second search result to a second output device that is different from the first output device.
