Condition monitoring device and condition monitoring method for wind power generation equipment

摘要

PROBLEM TO BE SOLVED: To provide a condition monitoring device for a wind power generation device capable of monitoring the state of an auxiliary system of the wind power generation device with a small number of parts. SOLUTION: This is a state monitoring device for a wind power generator, and an auxiliary motor power supply system is connected to a power supply side line connected to a power source and a plurality of auxiliary motors branched from the power supply side line. The state monitoring device includes a plurality of auxiliary motor side lines, and the state monitoring device includes a current measuring device for measuring the current flowing through the power supply side line and a control device for controlling the plurality of auxiliary motors. Is configured to be able to execute a single sequential operation mode in which each of a plurality of auxiliary motors is sequentially operated independently when the generator of the wind power generator is in a standby state in which power generation is stopped at a low wind speed. The current measuring device is configured to measure the current flowing through the power supply side line during the execution of the independent sequential operation mode by the control device.
