CORBA-BASED INTEROPERATION IN SUBSTATION AUTOMATION SYSTEMS

CORBA-based Substation Automation Systems

This paper talks about the implementation of the IEC-61850 standard using a CORBA middleware as communication mechanism. This standard specifies communication mechanisms for automation systems in electric substations. CORBA-based implementations of control systems open new perspectives for advanced control, because they ease the development of new functionality and enhance evolvavility of appli...

T Implementation Issues with IEC 61850 Based Substation Automation Systems

International Electro-technical Commission (IEC) has developed a new global standard, IEC 61850 for communication systems in power substations. This standard provides interoperability among the all communication devices within the substation. This paper presents basic features of communication systems proposed by IEC 61850, such as functional hierarchy, OSI-7 layer based communication, and proc...

Techniques for Securing Substation Automation Systems

Most critical infrastructure systems can be modeled as cyber-physical systems whose cyber components control the underlying physical components so as to optimize specified system objectives based on physical properties, physical constraints, and the current and estimated state of the system. Such systems usually require supports for security and performance guarantees: wrongly received or misse...

Introducing IEC61850 in Distribution Substations Substation Automation Systems

Substation Automation system

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...
