Wireless Communications in Substations

Mine, mine, mine: information theory, infostation networks, and resource sharing

The Infostations wireless data network architecture features discontinuous coverage and ultra-high radio rates for burst transfers of information between base and mobile. It has been shown previously that the infostations architecture can greatly increase the capacity of wireless data systems at the expense of increased delivery delay. In this work we explicitly consider the multiple access iss...

Software for Enhanced Monitoring in Integrated Substations

-Substation data integration is facilitated by existence and appropriate connection of Intelligent Electronic Devices (IEDs). Collecting data from IEDs and its processing facilitates performing data consistency checks, filtering out erroneous measurements, monitoring of switching sequences and substation topology transitions etc. Processed data may be used locally and/or communicated to remote ...

Cyber Security in Smart Grid Substations

This report describes the state of smart grid security in Europe, specifically the Netherlands, and the cyber security of substations in particular. The focus of this study is the perception of risks and threats in smart grid cyber security and the international standards implemented in smart grids. The created overview is based on semi-structured interviews with 13 experts originating from eig...

Lightning Protection of Ehv Substations in Iran

Extra high voltage (EHV) substations are extremely vulnerable to the hazard of lightning strokes therefore, the shielding of these substations with a highly reliable protective scheme (shield wires) is an essential undertaking. In this paper an attempt is made to clarify the design procedure for shielding EHV substations against lightning with special reference to Iran.
