چکیده
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 make the bus protection less sensitive with communication link performance degradation. IEC61850-9-2LE implementation is analyzed and process bus based on Ethernet technology is considered. Transient element based conventional bus differential protection is used with split busbar configuration and finally demonstrates the reliability and feasibility of proposed technique for digital substation.

Practical Applications of IEC61850 Protocol in Industrial Facilities
Various communication protocols are used within a typical industrial facility including Modbus RTU, DeviceNet and Profibus. These protocols used over the years have been in a Master-Slave configuration. Intelligent Electronic Devices (IEDs) are slaves to single or multiple masters with one-way communication with the IED acting as a data/controlled node to the master device. Control is implement...
متن کاملA Model of Bus Drivers’ Diseases: Risk Factors and Bus Accidents
Bus accident is a major health problem for bus drivers. To identify the risk factors involved in bus accidents and to design a model showing the relation between the risk factors and bus driver’s health status, 219 bus drivers who worked for travel agencies in two areas of west and central Iran were enrolled into this study. We used a questionnaire to gather information regarding both the bus...
متن کاملBus Protection Considerations for Various Bus Types
Choosing a bus protection scheme requires several key considerations. The complexity of bus protection varies considerably depending on such factors as the bus layout, allowed bus switching scenarios, availability of suitable current transformers (CTs), and maintenance issues. Buses with statically assigned zone currents are well suited for the use of high-impedance bus relaying (if suitable CT...

متن کاملPerformance Evaluation of Protection Functions for Iec 61850-9-2 Process Bus Using Real-time Hardware-in-the-loop Simulation Approach
With the evolution of Process Bus (IEC 61850-9-2), there is a need to assess the performance of protection schemes using process bus against those where traditional copper wires are implemented. Differential protection is the fundamental and most commonly used protection for transformers, motors and generators. In this paper a power system is modelled in SimPowerSystems and is executed in real-...
