In the recent years, with the advent of control systems, SCADA has played an important role in the field of automation. SCADA systems offer a means of controlling remotely located devices in an industrial process. Supervisory control can be combined with data acquisition wherein the data is obtained from the devices and it is processed further according to the user's needs. This paper offers an insight into the functioning of a typical SCADA system and its application for thermal power plant. The paper presents various types of architecture of such control systems, along with an overview of the security concerns pertaining to them.
SCADA system for a central heating and power plant
Modern process control systems are used in industrial automations for flexibility, modularity and reliability, employing state of the art technology based on three concepts: distributed control system (DCS), programmable logic controller (PLC) and most importantly supervisory control and data acquisition (SCADA). This paper deals with design and implementation of a SCADA system for a central heating and power plant, which is planned to supervise and control field distributed electric devices using Siemens equipment and software ldquoprocess control system 7rdquo (PCS7). The system also allows web-based applications via OPC and Web server by using the existing communication infrastructure. Redundancy is present at the server levels. The system is currently in use at COLTERM Central Heating and Power Plant South (CET South) of Timisoara.
Scada Systems Analysis for Industrial Procesess
2020
The paper presents an analysis of the operation and usage of SCADA data acquisition system. SCADA collects and records the values and statuses obtained from remote telemetry power system elements to enable control center operators to supervise and control the power system. The information transmitted by the automation systems of the remote control stations must be collected and processed at a central point. This function is performed by the network control systems that are installed in central locations, which are known as system control canters or control rooms.
TIP: An Umbrella Application for all SCADA-Based Applications for the CERN Technical Infrastructure
2015
The SCADA package WinCC Open Architecture (WinCC OA [1]) and the control frameworks (JCOP [2], UNICOS [3]) were successfully used to implement many critical control systems at CERN. In the recent years, the Industrial Controls and Electronics (ICE) group of the Engineering Department (EN) at CERN, supported other groups to re-implement the supervision of technical infrastructure, like Electrical distribution (EL), and Cooling and Ventilation (CV), using these tools. However, the fact that these applications are highly independent from the operation point of view, as well as their increasing number, renders operation uncomfortable since shifters are forced to continuously switch between them. In order improve the integration, EN-ICE is developing the Technical Infrastructure Portal (TIP) to provide centralized access to all WinCC OA applications, and extending their functionality including links to external databases and to a powerful localization system based on GIS. In addition the...

SCADA application of a water steam cycle of a thermal power plant
2013 5th International Conference on Modeling, Simulation and Applied Optimization (ICMSAO), 2013
The aim of this paper is to present the process of water treatment in a thermal power plant (TPP) in the one hand, and an application of a supervisory control and data acquisition system (SCADA) on the other hand. In fact, almost all critical industrial infrastructures and processes are managed remotely from central control rooms, using computers and communications networks. Thus, the architecture of the supervisory system and the different steps of the supervision application of the water treatment process of a TPP have been presented. Our contribution consists in programming and visualizing new parameters of the chemical analysis (pH and conductivity) of the water -steam cycle to a SCADA system. The achieved supervision application is going to facilitate the work of both laboratory and instrumentation agents of the water treatment process in the TPP.
The industrial control systems, which include supervisory control and data acquisition (SCADA) systems, distributed control systems, and other smaller control system configurations such as skid-mounted programmable logic controllers are often used in the industrial control sectors. The SCADA systems are generally used to control dispersed assets using centralized data acquisition and supervisory control. The SCADA systems are also distributed systems that are used to control geographically dispersed assets, which are often scattered over thousands of square kilometers, where centralized data acquisition and control are critical for system operation. They are commonly used in distribution systems such as water distribution and wastewater collection systems, oil and gas pipelines, electrical power grids, and railway transportation systems. In this article, the SCADA system used in the Yuvacik Dam and Reservoir operation, which is located in Kocaeli province of Turkey is reported and the problems associated with the system operation and their solutions are discussed. Keywords: Water resources; The effective and real time control of water resource; Dam management by SCADA; Problems and solutions
