Abstract: Present study focused on the utilization of solar
energy by the help of photovoltaic greenhouse solar dryer under
forced mode. A single slope photovoltaic greenhouse solar dryer has
been proposed and thermal modelling has been developed. Various
parameters have been calculated by thermal modelling such as
greenhouse room temperature, cell temperature, crop temperature and
air temperature at exit of greenhouse. Further cell efficiency, thermal
efficiency, and overall thermal efficiency have been calculated for a
typical day of May and November. It was found that system can
generate equivalent thermal energy up to 7.65 kW and 6.66 kW per
day for clear day of May and November respectively.
Abstract: A basic conceptual study of TCSC device on Simulink is a teaching aid and helps in understanding the rudiments of the topic. This paper thus stems out from basics of TCSC device and analyzes the impedance characteristics and associated single & multi resonance conditions. The Impedance characteristics curve is drawn for different values of inductance in MATLAB using M-files. The study is also helpful in estimating the appropriate inductance and capacitance values which have influence on multi resonance point in TCSC device. The capacitor voltage, line current, thyristor current and capacitor current waveforms are discussed briefly as simulation results. Simulink model of TCSC device is given and corresponding waveforms are analyzed. The subsidiary topics e.g. power oscillation damping, SSR mitigation and transient stability is also brought out.
