uncontrollable burning of wood, leading to deforestation. At some places, costly diesel is used for power generation. Use of diesel also involves substantial foreign exchange, and also causes pollution. As such, its use should be restricted as far as possible. The problem presented in this paper includes the design, development and application of Remote Area Integrated Power Station, which reveal several new aspects with respect to load control and power system dynamic behavior. The control of renewable energy sources through the Supervisory Control Data Acquisition (SCADA) is also presented to take care of seasonal variation. In the applications envisaged for this research exercise, the grid is not to be used due to
 

the Remote Area Application. Nevertheless, it is desired to generate a good sine waveform using PWM techniques. These factors make it necessary to evolve a comprehensive protection scheme with knowledge based controllers via extensive prior simulation and laboratory based experimental studies carried out at IIT Delhi [1-10].
