Title:
ELECTRIC POWER GENERATION FACILITY MONITORING SYSTEM, ELECTRIC POWER GENERATION FACILITY MONITORING METHOD, AND PROGRAM
Document Type and Number:
WIPO Patent Application WO/2017/195698
Kind Code:
A1
Abstract:
Provided are an electric power generation facility monitoring system, an electric power generation facility monitoring method, and a program that are straightforward to introduce. An electric power generation facility monitoring system 1 is provided with an acquiring unit 11 and an assessing unit 12. A measuring device 2 measures an output current from an electric power generation facility 4 which converts rotational energy of a rotor 442 into electrical energy and outputs an alternating current voltage having a reference frequency. The acquiring unit 11 acquires, from the measuring device 2, waveform data representing the waveform of the output current. The assessing unit 12 uses the waveform data acquired by the acquiring unit 11 to assess the presence or absence of abnormalities in a rotating block 41 which supplies a motive force to the rotor 442 of the electric power generation facility 4. The assessing unit 12 assesses the presence or absence of said abnormalities on the basis of at least one specific frequency component of the frequency spectrum of the output current, said at least one specific frequency being arranged on a frequency axis with a spacing, relative to the reference frequency, corresponding to the rotational speed of the rotor 442.
