PROBLEM TO BE SOLVED: To suppress resonance due to system interconnection of a wind turbine generator with a power system more effectively.SOLUTION: A power converter controller 46 is subjected to system interconnection with a power system, and is provided in a wind turbine generator where a generator generates power by rotation of a rotor having vanes. The power converter controller 46 includes a voltage sensor for measuring the generator terminal voltage, resonance component extraction units 74d, 74q for extracting electrical resonance component generated by system interconnection from the measurement results by the voltage sensor, and control units 82dand 82qfor controlling the current being fed to the power system so as to suppress the resonance component, based on the resonance component extracted by the resonance component extraction units 74d, 74q.

PROBLEM TO BE SOLVED: To provide a cable supporter which reduces a load to a cable and the possibility of cable disconnection in a part connecting with a sensor.SOLUTION: A cable supporter 1 according to this invention comprises: a support member holding a sensor and supporting a cable 21 led out from a sensor holder 20 provided at an installation surface 10 on the installation surface 10 side. The support member supports the cable 21 so that a bending angle of the cable 21 on the cable led out position 21a side becomes smaller than an angle formed when the cable 21 is not supported by the support member.
