Abstract
This paper describes modelling and testing of a
digital distance relay for transmission line protection using
MATLAB/SIMULINK. SIMULINK’s Power System Blockset
(PSB) is used for detailed modelling of a power system
network and fault simulation. MATLAB is used to implement
programs of digital distance relaying algorithms and to serve
as main software environment. The technique is an
interactive simulation environment for relaying algorithm
design and evaluation. The basic principles of a digital
distance relay and some related filtering techniques are also
described in this paper. A 345 kV, 100 km transmission line
and a MHO type distance relay are selected as examples for
fault simulation and relay testing. Some simulation results
are given.

fg thanks very much tanks alot of this post
mohamed ahmed badr

how can i get this examples or simulation??

Hi ,

I was unable to find any MATLAB simulations model related to distance protection. I would like to implement Quadrilateral relay simulink model. Kindly I request you to provide me this model. So that it will be great help for further project work. Please suggest me how can I get any simulink example cases related to distance relay. my email id
