Whenever a fault or disturbance in a power system occurs several IEDs are triggered and several data recordings are generated. Automated processing and analysis of substation disturbance data is an effective way to filter important information from the collected data and convert the extracted information into knowledge. Configuring automated analysis systems to allow for efficient data integrat...

Gas-insulated substations (GIS) have different specifications in proportion to air-insulated substations. Transformer failures related to lightning and switching are often reported in the gas insulated substation (GIS). This problem is the voltage magnifications due to reflections of switching and lightning surges at various junctions within the GIS. thereby overvoltages in GIS are more importa...

Green and sustainable power is the need of the day. With widening supply and demand gap, power management has become one of the most critical areas of concern all over the world. India’s energy consumption is increasing at one of the fastest rates in the world. Hence, we require Substation Automation Systems in the present day substations to efficiently control and deliver power. The main objec...

The creation of the data model and the configuration of the communication system represent essential tasks of engineering substation automation systems With SCL (Substation Configuration Description Language) the system standard IEC 61850 provides a standardized formal representation of the data model and communication configuration of substation automation systems. The substation model of SCL ...

IEC61850 communication standard for digital substation automation creates a new way to think about conventional protection scheme and configuration of substation. The presence of communication link in process bus makes a revolutionary change for future digital substation. This paper discusses briefly about process bus architecture and presents a new approach of thinking in busbar structure to m...

500kV substation is especially important to the grid of our country, once it encounters lightning damage, the safety and reliability of the whole power system will be directly affected. As lightning intruding waves will cause overvoltage on electric equipments by intruding from the transmission line or straightly stroking the substation, which seriously influences the insulation level of equipm...

The IEEE1588 network time synchronization, matched with smart substation information network transmission, is becoming the next generation advanced data synchronization of the smart substation. It is known that the inherent asymmetry error of the network synchronization approach in the smart substation is highlighted, which is concerned particularly. This paper models the synchronization proces...

The smart-grid concept takes the communications from the enclosed and protected environment of a substation to the wider city or nationwide area. In this environment, cyber security takes a key role in order to secure the communications. The challenge is to be able to secure the grid without impacting the latency while, at the same time, maintaining compatibility with older devices and non secu...

Distribution Substation Automation in Smart Grid Substation Automation (SA) can provide integral functions to the distribution grid automation. As more IED devices are installed to the distribution network, the need for IED management, control, and the corresponding advanced application operation is a growing imperative. Moreover, the Smart Grid applications, such as the Integrated Voltage and ...

The technology in intelligent terminals enables communication from the process level to the SCS, substation, SCADA/EMS, and the network levels. Any function and parameter can be programmed and changed remotely. Automatic sequences can be included on bay and substation levels utilising the SCS. In addition, with serial communication, binary inputs, and user programming, it is possible to adapt f...
