Analysis Of Ac Voltage Controller Based Electronic Load Controller For Self-Excited Induction Generator

The paper ‘Performance Analysis of Microcontroller based Electronic Load Controller’ is an approach for design, fabrication and performance analysis of microcontroller based ELC for 300 Watt Pico hydro controller. Electronic Load Controller (ELC) is an approach for regulating total power in the system with Pico-hydro power plant. The paper presents a unique method to maintain the system performance by regulating the generated power. The system voltage and current is measured by microcontroller to calculate the consumer power. Based upon the consumer power the dump power is varied accordingly. The performance analysis of ELC unit was done with power source from Nepal Electricity Authority (NEA) grid line as well as with separately excited induction generator under various loading conditions. The different resistive, capacitive and inductive loads were taken into consideration and the performance of the system based on voltage, current and power profiles were obtained.Kathmandu University Journal of Science, Engineering and TechnologyVol. 13, No. 1, 2017, 20-35

Induction generators are widely used to extract the energy from renewable sources, particularly as a wind power generator either grid connected or isolated operation. The problem associated with stand-alone mode operation is voltage and frequency control. An electronic load controller is used for frequency / voltage control. It uses PI controller to generate the gating signal for the DC chopper. This method has the fault of bad dynamic response and thedistortion of output voltage at zero-crossing. To overcome the defect of PI controller when steady state error is equal to zero, a one cycle control technique suggested and implemented. Simulation of wind driven self-excited induction generator (SEIG) performance is studied and results are discussed.
