VERIFICATION TESTING OF A WELL-MATCHED WIND TURBINE POWER GENERATION SYSTEM

Due to Malaysia's typically low and fluctuating wind speeds, it is crucial to carefully select and match appropriate wind turbine generators to ensure efficient power production. However, the data provided by manufacturers for wind turbine generators often differs from actual operational performance. This study aims to develop a test rig and setup to characterize the generator constant. The verification testing involved validating a 1kW generator with a rated voltage of 48V and a rated RPM of 380 under both unloaded and loaded power systems. The results showed that the calculated generator constant (Kv) for the 1kW 48V generator was 4.56 rpm/V when the system was unloaded. When the system starts charging, using an Energy Storage Capacity (ESC) of 4.8kWh, the Kv value increased to 63.13 rpm/V. The maximum charging power (Pc) that could be generated under these conditions was 944W at 533 rpm. According to the results, at the generator's rated RPM of 380, the maximum charging power attainable is 608W. This test result contradicts the manufacturer's claim that at a rated RPM of 350, the power output is 1kW.
