Impact of STATCOM on distance relay

2014 International Conference on Circuits, Power and Computing Technologies [ICCPCT-2014], 2014
This paper presents simulation of distance relay with STATCOM and simulation results for investigating the operation of Distance relay in a power system containing flexible alternating current transmission (FACTS) controller such as static synchronous compensator (STATCOM). When STATCOM is connected at the midpoint and fault is after STATCOM have great

A Methodology for Distance Relay Modeling

IEEE Latin America Transactions, 2018
A methodology for modeling a distance protection relay in a real-time digital simulator is proposed. The relay model includes the main functionalities of digital relay architecture, the mho and quadrilateral distance protection elements and the fault diagnosis.

Proceedings in distance relaying

6th International Conference on Developments in Power Systems Protection, 1997
Detailed reports on power system fault histories are now available, leading to a new quality of fault analysis. The sequence of events and the reactions of the power system protection relay during network disturbances become transparent and reproducible.

A simplified unit for distance relaying

Electrical Engineering, 1954
One method of providing an intermediate step between the performance, cost, and complexity of overcurrent and conventional 3-zone distance relays is described here. RELAY APPLICATION naturally varies widely with the practices of the various operating utilities. However, it seems to be a general trend that for low-voltage short lines, simple overcurrent

Microprocessor-based distance relay

Proceedings. National Power Engineering Conference, 2003. PECon 2003., 2005
This paper presents the design and operation algorithm for the protection of short transmission line using microprocessor-based distance relay. The characteristic of a distance relay is realised by comparing voltage and current at the relay location.

Operating experience with distance ground relays

Electrical Engineering, 1946
DISTANCE RELAYS for protection against wire-to-wire, two wire-to-ground, and three phase faults on transmission lines have met with wide acceptance. However, the use of distance relays for protection against single wire-to-ground faults has been limited to relatively few installations.

Testing of high speed distance relays

Electrical Engineering, 1933
This paper describes the various test methods which have been evolved during three years by The Tennessee Electric Power Company, which pioneered the use of reactance type distance relays in this country. Specific examples with diagrams are given. New considerations brought about by the use of high speed distance relays are discussed, including their ...

Fundamental basis for distance relaying

Electrical Engineering, 1931
For single-line protection, with the exception of pilot-wire, or superposed high-frequency methods, distance relays form the nearest approach to the theoretically ideal system. Except for errors due to fault resistance, these relays operate accurately according to the relative distance to faults.

Numerical conic distance relay

2015 International Conference on Innovations in Information, Embedded and Communication Systems (ICIIECS), 2015
Relays are the key device that is used for the protection of a power transmission system. The paper presents the development of a numerical distance relay, based on conic characteristics. The developed distance relay is intended for the protection of transmission network so that the scheme would exclude most of the conditions for which tripping is ...
