C.A.E. Software for Transmission Protection System: Puget Power Experience
IEEE Transactions on Power Delivery, 1987One major concern of a protection engineer is to achieve successful coordination of all relays in a transmission network. This tedious and laborious process is usually accomplished manually at present. In this paper we present the results of a Computer-Aided Protection System based on our experimentation with the entire 115 kV transmission network of ...

Active power differential algorithm for protection of transmission lines
PowerTech Budapest 99. Abstract Records. (Cat. No.99EX376), 2003A differential algorithm for phase selective detection of high impedance single-phase-to-ground faults (HIF) on high voltage lines is presented. It is based on the recognition of the fundamental frequency active power consumption of a resistive fault.

Performance analysis of power differential based transmission line protection
2017 International Conference on Energy, Communication, Data Analytics and Soft Computing (ICECDS), 2017This paper deals with investigation of novel fault detection for the protection of transmission line. Conceptually the difference of the average quantities for phase active power entering and leaving the lines are compared Computation of these quantities is carried out via simulating a tie line connecting two power system networks using MATLAB.

A backup wide‐area protection technique for power transmission network
IEEJ Transactions on Electrical and Electronic Engineering, 2017This paper proposes a wide‐area backup protection technique for transmission lines using a limited number of synchronized phasor measurement units. A binary integral linear programming is used for optimal placement of phasor measurement units to achieve fault observability.

Some observations for distance protection of power transmission lines
IEEE Southeastcon 2009, 2009This paper presents some observations related to distance protection for power system transmission lines. Classical distance protection relays adopt the line terminal voltage and line current to calculate the distance between the fault and the relay location and then make a decision on whether a tripping signal should be issued and, if so, what the ...

Galvanic Cathodic Protection for Power Transmission Tower Grillage Foundations
Materials Performance, 2016Cathodic protection (CP) of underground steel structures is a mature technology for structures with simple geometries, such as pipelines and storage tanks. Nevertheless, this technology is not well-adapted to structures with irregular geometries, where application of conventional anode bed designs are formidable due to the interplay of geometrical and ...

Experimental evaluation of power differential relay for transmission line protection
2009 IEEE/PES Power Systems Conference and Exposition, 2009An experimental evaluation of a power differential relay is conducted and the results are described. The experimental setup consists of a generator connected to the network via a transmission line protected by the power deferential relay. The relay input signals, fundamental active and reactive powers, are locally computed from the complex product of ...
