Functional and application testing is the most widely accepted testing practice for protection and control systems and is required to ensure that a system Integrity protection Scheme (SIPS) and each of its components are going to operate as designed under different system conditions. the paper discusses in detail the requirements for functional testing of devices and distributed functions used in SIPS. the methods for testing of both types of systems are proposed.

To deliver the increasing capacity and reliability of train services which railways must deliver, the electrification fixed system must itself be highly reliable and available. Main line railways demand high power transmission and traction system energy demand will continue to grow. there remains however the need to contain and reduce first and whole life cost. this paper sets out how IEC 61850 can become an integral part of the answer to these challenges.

A response based protection scheme which is capable of applying countermeasures as last line of defense against line overloading is presented. the scheme utilizes on-line measurements of voltages and currents, as well as line material parameters and weather data to apply a thermal on-line forecast. thus, it is possible to estimate the remaining withstand time of all concerned overloaded lines. therewith, suitable countermeasures and the optimal time for their execution can be determined. For the proof of concept, a detailed modeling concept of the thermal behavior of overhead lines in grid operation is performed in dynamic powersystem simulations.

the MV networks operated by ESB Networks (ESBN) exhibit very high levels of static and dynamic asymmetry. Historically, application of arc suppression to such networks was considered impractical or unsustainable. this paper outlines the trials and live earth fault tests that confirmed how modern techniques make arc suppression in such networks successful. Further, the addition of faulted phase earthing ensures that fault site conditions are optimised where tripping is not necessary. the scope of earth fault protection employed and techniques used for high efficiency fault location are outlined.

the microprocessor-based protection for high-voltage magnetically controlled shunt reactor (MCSR) is presented in this paper. protection schemes comprise working winding protection, control winding protection, compensation winding protection and backup protection. Along with discussing the overall protective schemes, the focus of this paper has placed on the control winding protection, which is an essential part of the overall MCSR protection, on the basis of fault characteristic analysis. Careful protection considerations that required due to the particular feature of MCSR are also discussed in each part.

Protecting electricity distribution networks is becoming increasingly challenging with continual demands to improve performance. Invariably, the solution involves capitalizing on the developments in digital relaying and communications. this paper describes the findings of an investigation into extending IEC61850 beyond the substation in order to provide network wide communications. It introduces the basis for Fault Passage protection for protecting distribution feeders using an associated internet communications scheme. this protection builds on widely established techniques based on instantaneous and IDMT overcurrent relaying and provides reduced tripping times for faults on the protected feeder while retaining the advantages of the inherent remote back-up protection.

this paper presents the design of a new substation automation system architecture based on industrial automation technology, the development of an IEC 61850 compliant distance protection scheme and its test results. the proposed centralized structure means benefits for system integration since a higher degree of standardization can be achieved. Furthermore the approach guarantees manufacturerindependent and flexible IEC 61131-3 programming. thus any implemented protection and control functions are portable and which saves otherwise required redevelopment effort in case of a required migration process.
