Integrated Dam Automation System (IDAS) is intended to be an appropriate option to meet out the existing challenges of dam operating system. The system is incorporated into Programmable Logic Controller (PLC), Distributed Control System (DCS) and Supervisory Control and Data Acquisition (SCADA) technology. The PLC is used to control the gate valve position of dam through the measurement of water level in the dam. DCS is utilized to get continuous monitoring and data acquisition of the working condition of the dam. The main function of the proposed model is to automate the dam channel gate operation in accordance with the presence of water level in different dams using DCS to centralize thé system. The flow of water is measured frequently using water flow measurement sensors in both the case of the inlet and outlet of the dam. The concept of PLC will eradicate the occurrence of failure and improve the precisión of flow of water resource in the proper manner. The main reason for using PLC is to achieve various functions and controls like gate control, level measurement and automatic start/stop sequencing and instrumentation also possible in a protected way. This project is made to ensure the use of PLC and DCS to control and automate the dam in a high accuracy rate. To enhance the reliability and safety procedures of the dam, it is very important to collect dam operational data in real time monitoring system and such case, here the DCS to be enclosed with this project. The remote DCS is incorporated with the data like flow rate, temperature and water , level by the help of various sensor installations. The acquisition of data from remote DCS unit is directed to centralize SCADA will help for future consideration and also gives feedback to work with the PLC system to alter its operation in proper sequence to avoid accidents and failures. The SCADA system of this project will stores the data of sequence and various parameters of the dams at different places are collected from each DCS, in a very rapid manner to achieve perfection and full utilization of water resource. As IDAS, is an integrated system of many dams in a centralized station, therefore the system in need to achieve quick transfer of PLC and DCS data to the centralized system, which triggers the main control of the dam. The transfer of information and controlling signal is done by using satellite communication (GPRS or GSM system). The receiver end present in the dam will be actuated by means of controlling signal transferred from centralized dam controlling station (SCADA to Remote DCS). This ensures that an emerging new technological development and could raise the technological infrastructure of the dam.
