Narrative
Transmission Automated Control (Baseline) describes a set of functions that are typically automated within a substation, but are not directly associated with protection, fault handling, or equipment maintenance. In general, they serve to optimize the operation of the power system and ensure its safe operation by preventing manually generated faults. These functions include:
- Changing transformer taps to regulate system voltage
- Switching capacitor banks or shunts in and out of the system to control voltage and reactive load
- Interlocking of
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 :

Large Scale Substation Automation: Overcoming Technical Challenges
Jan 13th
Integrating components for substation automation at a handful of substations can be achieved with custom fit solutions for each integration effort. Automation of dozens of substations, on the other hand, requires a systematic approach involving the application of data and integration standards and disciplined project management and engineering processes. The use of proven systems for large scale implementation, combined with an experienced systems integration team, helps ensure the realization of enterprise wide benefits.
There are many substation automation architecture choices available today providing varying levels of redundancy and scalability, but the application of standards and process to
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
Integrated Utility Communications Project
Jan 12th
One can consider IntelliGrid Architecture to be the third wave of focused efforts endeavoring to define reusable architectural components for energy enterprise and industry-wide applications. The first two waves of industry efforts were the Integrated Utility Communications Project and the UCA® 2 Effort.
Integrated Utility Communications Project
The first effort was performed through the efforts of the Integrated Utility Communications Project, which initiated by EPRI® in 1986. Through these initial efforts, a cadre of utility domain experts was consulted and their views combined into the first incarnation: UCA (Utility Communications Architecture). What was most impressive about this effort… Continue reading
De facto standard for seamless DTS integration: Direct link to SCADA
Jan 11th
The intrinsic temperature measuring system DTS based on LIOS Technology’s design, with fibre optic sensors either installed within the power cable’s cross section (FIMT – Fibre in metal tube ) or attached to the exterior of the cable, makes it possible to record the temperature profile along an entire cable route continuously, and to pinpoint the exact location of hot spots within a metre.
Most commonly the measured temperature profile data is transmitted via standard interfaces from systems of the DTS as required, and be either displayed or further processed by PC, PLC or SCADA systems. As a result… Continue reading
