Real- Time Implementation of Hydroelectric Power Plant Using PLC and SCADA

This paper emphasize on controlling the process variable parameters such as level and flow with real time implementation of gate control of hydroelectric power plant using Programmable Logic Controller. In this work, a programmable logic controller is used as an industrial computer playing the role of a control device and push buttons, level and flow sensors provide incoming signals to the control unit. The prototype model is provided with five levels in the upper tank and two levels in the lower tank and depending on the level sensor outputs the ladder logic is actuated. This work uses PLC of ALLEN BRADLEY MICROLOGIX 1200 inbuilt with 24 digital inputs and provides 16 potential free outputs to control the miniaturized process depicted in the work.
