Earth Station Power controller can be designed by several methods by using different processors and programming codes. For coding we can use different languages as per different processor or hardware, embedded C, Hardware description language (HDL), etc. Power controller design is nothing but a design of algorithm where multiple solutions are provided for power failure condition and power consumption conditions. We have used different power sources for load consumption (Earth Station), our primary power source is Solar Panels and Secondary power source is Diesel generator. Our main objectives are avoiding Failure conditions and utilize maximum power from solar panels. As per objective, load consumption and failure conditions our algorithm and flow chart are designed accordingly hardware specification has selected for our prototype. Solar panels, charger circuit, battery bank, inverter, load and controller these are main hardware. © 2016 IEEE.
