Content Inside : Generator rotor thermal sensitivity is a phenomenon found on the generator rotor causing change in vibration as the field current is adjusted. Thermal Sensitivity Testing The test is conducted to prove whether the vibration problem is caused by field current changes or prime mover force changes. Vibration changing ...

Part of Content : This paper presents the converter design for a 20kW wind turbine generator. The converter consists of a phase controlled rectifier and a DC/DC boost converter. The rectifier makes the generator AC voltage match the DC voltage while the boost converter keeps the DC voltage constant. POWER FLOW ...
