Abstract

The purpose of this thesis work is to design, develop and test a measurement system for performance evaluation and simulation of a small wind turbine generator in a laboratory. There is no such system available to easily check the torque, speed and power of a motor to be used as a generator at a series of rotational speed. In order to reduce the chance of failure and to make sure that the wind turbine generator will be able to operate at maximum or at least produce favourable output power, it has to be tested with varying rotational speeds before it is installed on top of the tower of a wind power rig. The proper testing system would consist of a controllable artificial driver and device to monitor some parameters such as applied rotational speed and torque, and also the resulting voltage, current, and the power generated by the turbine generator. An AC motor with frequency inverter is used in this project as the driver to vary the input speed. To measure the torque, an in-house designed Wheatstone bridge with 4 active strain gauges cooperated with slip rings and brushes are used to convert the mechanical torque variation on the connecting shaft into resistive change and finally into an electrical signal. Tachometer is used to measure the shaft speed. The output power is obtained by using multimeters to measure the resulting current and voltage. Altogether, the measured parameters will determine the characteristic performance of the wind turbine generator that can be expected if the generator is installed later.
