Automation means Delegation of human control to machine. A PLC (Programmable Logic Controller) is a device that was invented to replace the necessary sequential relay circuits for machine control. A SCADA (Supervisory Control & Data Acquisition System) is used to control the process where person cannot go or stay for longer period. The aim of tis paper is to provide information about electricity can be generated from Renewable sources & how its transmission done using automation system. Renewable Energy consists of energy generated from natural and unlimited sources, which include wind, solar, biomass and hydroelectricity. Programmable logic controllers (PLC) can be used for control & automation in Distribution of Energy. The main reason for this is cost effectiveness. Various functions and controls can be achieved by programming the PLC.They can be used for full plant automation including governing of auto operation includes speed control, load control, excitation control, and level control automatic start/stop sequencing, gate control, start/stop of auxiliary systems, and protection requirement etc. Functions other than control like continuous monitoring, data recording, instrumentation and protections can also be performed. For remote operation, communication with PLC can be performed. For continuous monitoring purpose, a personal computer can be interfaced with PLC and continuous data can be recorded regularly. In this paper I used different methods for generation of electricity like wind, PV (photovoltaic), hydro, biogas & distributed using PLC & controlling using SCADA.
