|SCADA systems, (supervisory, control and data acquisition), play a vital role in the operation of electricity utilities. SCADA systems are used to monitor and control their equipment, which is usually spread over a large geographical area. They have to gather information from a number of field RTUs (remote terminal units) over a variety of communications links, and present the information in a clear and concise way to the operators. While implementing SCADA systems enhance utilities’ performance, they also face a number of challenges - installation in harsh electrical and physical environments, rapidly evolving technology and short product life spans, data overload, and a shortage of skilled resources in the industry.
Since 2000, Virelec has developed its capability to supply SCADA systems in a number of areas, and is a VAR (value-added reseller) for the GE Energy Systems platform. We specialize in the applications described below, providing design, assembly, configuration, testing and commissioning services.
The supply of DARTs (Distribution Automation Remote Terminals), mounted on pole-tops to monitor and control motor-operated distribution switches.
Electricity Market Participation:
The supply of compliant interfaces to extract, concentrate, and transmit data from the substation to the system operator using approved communications equipment and protocols.
Substation Control Systems:
The supply of complete substation control systems, which concentrate and use data from substation IEDs, instrument transformers, transducers and hard-wired inputs to implement the local and/or remote control of the substation.
