This thesis presents the SCADA (Supervisory Control and Data Acquisition) system, which is one of the most advanced automatic control systems used in power generation and distribution automation to ensure high-quality energy. It introduces the general architecture of SCADA systems and their key hardware components. The applications include control, operation, supervision, measurement, instrumentation, and SCADA services within the power distribution system. This reflects the modern trends in power system protection, control, and security. In this project, a control model was implemented using an HMI (Human-Machine Interface) screen to control the rotational speed of a specific motor by adjusting the frequency. Additionally, wireless remote control was integrated, providing significant advantages in managing and quickly controlling various subsystems in any power station. This method enhances system responsiveness and improves the overall efficiency of the control mechanism.

Traditional power grids are now transformed into Smart Grids (SGs) in order to solve the problems of energy wastage, energy control, uni-directional flow of information, growing energy demand, reliability, measurement and security.Smart grids increase the automation, coordination and connectivity between these electricity suppliers, electricity usersand networksused in local distribution tasks and long distance transmission. Smart Grids offer bi-directional energy flow between electricity service providers and electricity consumers which involve power generation, transmission, distribution and utilization systems. Smart Grids utilize various devices to monitor, analyze and control the grid. These devices are deployed in great numbers all over the distribution centers, consumers’ premises and in power plants. Therefore, Smart Grid requires connectivity, automation and the tracking of such devices. SCADA connection to the Internet is advantageous in terms of generation, data viewing and control. SCADA infrastructures such as electricity could also be incorporated in Smart Grids. Adopting advanced, cloud computing technology and smart technologies in SCADA of distribution system for smart monitoring, smart metering, distributed system automation and optimization, power system control, distributed intelligence, data decentralization, data sharing and forwarding, flexible communication architecture, distributed generation and storage, extensibility and interoperability. This project report focuses on future SCADA for smart grid and decentralized distribution system and literature review on smart grids.
Design of a SCADA Based Monitoring Platform for an Old Conventional Power Distribution Network
International Journal of Innovative Science and Research Technology ISSN No:-2456-2165, 2020
Supervisory Control and Data Acquisition System is widely used throughout the industry for better monitoring and control of any plant. However this requires a plant hardwires and sensor to be controllable and compatible for monitoring and control. The most convenient way to apply SCADA system is to use intelligent devices to connect to SCADA system. In a large plant consisting of components of very old technology application of SCADA system is not straight forward. When the plant is distributed in large geographical area with power system components located at scattered area it require special approach to convert the old technology based devices to bring into a common platform which is understood by the SCADA system. Hot Lab Utility & Engineering Services Section has designed a platform to monitor the power distribution system of a conventional Radiological facility in BARC to monitor its power system utilities for providing better services to the plant. The paper describes the design of a distributed SCADA system for monitoring power distribution system catered in Class I, II, III, IV categories. I.
Interfacing with SCADA System for Energy Management in Multiple Energy Carrier Infrastructures
International Conference on Information Society, 2016
In order to provide more advanced and intelligent energy management systems (EMS), generic and scalable solutions for interfacing with numerous proprietary monitoring equipment and legacy SCADA systems are needed. Such solutions should provide for an easy, plug-and-play coupling with the existing monitoring devices of target infrastructure, thus supporting the integration and interoperability of the overall system. One way of providing such holistic interface that will enable energy data provision to the EMS for further evaluation is presented in this paper. The proposed solution was based on the OpenMUC framework implementing a web-service based technology for data delivery. For testing the system prior to an actual deployment, data simulation and scheduling component was developed to provide a low-level data/signal emulation which would replace signals from the field sensors, monitoring equipment, SCADAs, etc. Furthermore, the proposed interface was implemented in a scalable and adaptable manner so it could be easily adjusted and deployed, practically, within any complex infrastructure of interest. Finally, for demonstration and validation purposes, the campus of the Institute Mihajlo Pupin in Belgrade was taken as a test-bed platform which was equipped with SCADA View6000 system serving as the main building management system.
Secure SCADA framework for the protection of energy control systems
Concurrency and Computation: Practice and Experience, 2011
Energy distribution systems are becoming increasingly widespread in today's society. One of the elements that are used to monitor and control these systems are SCADA (Supervisory Control and Data Acquisition) systems. In particular, these control systems and their complexities, together with the emerging use of the Internet and wireless technologies, bring new challenges that must be carefully considered. Examples of such challenges are the particular benefits of the integration of those new technologies, and also the effects they may have on the overall SCADA security. The main task of this paper is to provide a framework that shows how the integration of different state-of-the-art technologies in an energy control system, such as wireless sensor networks, mobile ad hoc networks, and the Internet, can bring some interesting benefits, such as status management and anomaly prevention, while maintaining the security of the whole system. Thus operators in field may know in real-time the actual state of the system or subsystems with the possibility of collaboratively interacting with other (close or distant) operators, and in the worst case to have the capability for attending an anomalous situation before this happens, i.e. to prevent it. These anomalous situations are generally associated to a failure or a (logical or physical) threat detected in the field. To detect such anomalies it is necessary to deploy sensor nodes with the capability of alerting, for instance, to nearest operators with MANET devices on hand or a central system through the Internet. As a result, a new framework is proposed for the literature, where WSNs, MANETs, and the Internet play an important role in monitoring processes, offering continuity and reliability of services. Likewise, a security analysis for this framework is provided to guarantee a secure applicability in a real context.
Aplication of Internet in the Scada System
Supervisory Control and Data Acquisition (SCADA) system employ a wide range of computer and communication technologies. Advances in the technologies have helped in improving the effectiveness of SCADA. One such recent technological development is Internet and the World Wide Web. The operational and commercial needs of the power industry require information systems to not only perform traditional functions but also support many of the new functions, specifically to meet the needs of competition with deregulation. The rapid developments of the Internet and distributed computing have opened the door for feasible and cost-effective solutions. This paper describes and demonstrates a unique Internet-based application in a substation automation that is implementing based on the existing control system, SCADA system and information technologies (IT).
