SCADA stands for Supervisor Control And Data Acquisition
Jan 16th
SCADA stands for Supervisor Control And Data Acquisition. It is a production automation and control system based on PCs.
It is widely used in many fields :
e.g. power generation, water system, oil industy, chemistry, automobile industry.
Different fields need different functions, but they all have bellow features :
Graphical interface Process simulation Real time and historic trend logging Alam system Data acquisition and recording DataSCADA, VAR, and phase load balancing smart grid software

Substation Automation Basics – The Next Generation
Jan 13th
There is an increased focus on transmission and distribution investments to address aging and distressed infrastructure. Previously voluntary reliability programs under the North American Electric Reliability Council (NERC) are transitioning to mandatory reliability standards, requiring self reporting and imposing penalties for non- compliance. Utilities are placing a greater emphasis on real time, enterprise wide information to secure the right information and the right time to enhance reliability and to better manage asset management and operations and management.
Intelligent electronic devices (IEDs) being implemented in substations today contain valuable information, both operational and non-operational, needed by many user groups within
DIGITAL CONTROL SYSTEMS
Jan 12th
With the introduction of deregulation and competition in the electricity distribution networks, reliability and security of supply coupled with low operation costs have become the key factors for the utility providers to compete and meet customer satisfaction.
Such requirements led utilities to invest in continuous monitoring and immediate intervention by installing intelligent electronic devices and data concentrators to collect vital information and execute commands from a remote control centre.
Digital control systems are now forming an integral part of modern substations. Numerical data is exchanged between the control centre and the various substations connected to it through standard… Continue reading

Smart Grid
Jan 1st
A smart grid delivers electricity from suppliers to consumers using two-way digital technology to control appliances at consumers’ homes to save energy, reduce cost and increase reliability and transparency. Such a modernized electricity network is being promoted by many governments as a way of addressing energy independence, global warming and emergency resilience issues. Smart meters may be part of a smart grid, but alone do not constitute a smart grid.
A smart grid includes an intelligent monitoring system that keeps track of all electricity flowing in the system. It also incorporates the use of superconductive transmission lines for less… Continue reading
