Role of SCADA in Hydro Power Plant AUTOMATION.

Sukhmeet Kaur, Namita Kathpal, Nitika Munjal.

Automation is the use of control systems, intelligent electronic devices, instruments and new communication technologies to enhance the quality of work, better monitoring and controlling of the system to reduce the human interface with system. Automation plays an increasingly important role in the world economy. Automation has had a notable impact on power sector beyond manufacturing industries also. Now a day’s Power plant control systems have evolved from SCADA-centered platforms to communicate with industry standard hardware and software, and then to integrate power plant automation systems with almost unlimited connectivity. The system will embrace the latest information and communication technologies (ICT), and multiple communication channels (some traditional and some personal, such as instant messaging). Interoperation of various control system in power house and substation automation system from SCADA was a challenge in past decades, but with the development of IEC 60870 - 5 - 103/104 and IEC 61850 interoperation of various automation systems is possible. IEC 60870 standard is used for telecontrol in electrical power system such systems are used for controlling electrical transmission grids, power house control system like turbine controller, Protection system, Excitation System and other geographically widespread control system. This paper describes a SCADA System for hydro power plant automation in compliance with the various IEC standard and interfacing protocols to ensure interoperability among the various devices.
