This paper is focused on the automation of gates of dam with using the current smart technologies of Programmable Logic Controller (PLC) and SCADA. A dam is an artificial reservoir made to collect a huge volume of water across a river or water body and use it for the purpose of generation of electricity, irrigation, water conservation and stream regulation. Due to uneven rainfall in India, it is not possible for some areas to get regular supply of water or due to their geographical conditions a huge amount of water runoff. So, water collected in the dam is very essential for these areas. Hence, it is necessary to make dams gates automatic for the wise use of available water resource, and increase efficiency of dams that would result in best commercial, agricultural and social benefits. A large number of dams in the world still uses manual system for the controlling of gates of dam, which employs humans for the desired operation, that may have the chances of human error resulting in improper regulation of the stream and also decreases the overall efficiency. To overcome these problems an Automation system is essential that comprises of PLC and SCADA to control the gates of dam by using a single system operation. The operations of dam gates are based on the feedback signals from the level sensors (Digital Input) and float sensor (Analog Input). The forward and reverse operation of dc motor of gates is achieved with the PLC.Ladder programming is used to implement the wholeoperations of this system. SCADA is used for remote monitoring for a number of dams from a central controlling station.
