In this study, an adaptive noise suppression filter based control algorithm is proposed for integrated voltage and frequency controller (IVFC) of a speed governor-free hydro turbine driven single-phase self-excited induction generator (SEIG). A voltage source converter (VSC) is employed to control the terminal voltage of SEIG with adjustable reactive power. It also mitigates the harmonics injected...
This paper deals with an implementation of an electronic load controller (ELC) using a digital signal processor (DSP) for regulating the voltage and frequency of an offgrid induction generator system (IG) that can supply electricity in remote areas of countries with high year-round rainfall. The proposed generating system consists of IG, ELC and nonlinear consumer loads. The ELC is combination of...
The TMS320 - based control systems have numerous advantages. The high processing speed of the TMS320 family allows sophisticated control techniques to be used to build a high-precision control system. The experimental results for the V/f control of 3-hp induction motor drives controlled by a digital signal processor micro 2407 TMS320 chip have verified the effectiveness of the proposed scheme. The...
In this paper, a simple adaptive speed control for induction motor is described and implemented using dedicated Digital Signal Processor (DSP). The controller structure design is based on voltage/frequency (V/Hz) control scheme that transforms the three phase motor speed into voltage and generating input of sine wave of PWM. Using these voltage components, the AC induction motor can be handled in...
This paper presents design and implementation of Digital Signal Processor (DSP) based induction generator controller (IGC) to regulate the voltage and frequency of single phase self excited induction generator (SEIG) which employs a three phase squirrel cage induction machine, suitable for stand alone power mode employing unregulated turbine such as micro-hydro power generation. A three phase induction...
Matrix converters (MC) are compact voltage source converters capable of providing variable voltage and variable frequency at the output. Compared with traditional topologies the MC does not require an intermediate DC link and provides sinusoidal output waveform with minimum higher order harmonics. To yield higher rms O/P voltage, it is proposed to use space vector modulation (SVM) algorithm for the...
