SIMULATION OF PARALLEL WORK OF ASYNCHRONOUS GENERATORS IN AUTONOMOUS INSTALLATION FOR CHARGING BATTERIES
Using autonomous wind turbines (AWT) with asynchronous generators (AG) in remote areas is one of the available solutions for power generation and electric power consumers.
It should be emphasized that despite the complexity of the circuits to control AWT random nature of change of wind speed and gusts it can lead to hypertension output of the generator mode. AWT with hypertension using pulsed converters (PC) to charge the batteries allows direct connection to a consumer that not only improves the working conditions of wind turbines, but also simplifies regulation voltage and frequency.
The work task design simulation models in parallel operation AWT AG to charge batteries during variable wind speeds and related this change duty cycle output signal PC. The development of the installation model is based on the software package Matlab / Simulink / SimPower Systems.
Studies have shown that in the case of the coincidence of voltage drops at the output of the converters (the ideal variant), the total charge current of the bidet is equal to the sum of currents from the generators. When a mismatch output voltage converters, as a result of various wind speeds in the area of the generator (real version), there should be a shift pulse charging current supply terminals on the batteries.
