This paper presents the effects of instrument transformers connection points on the measured impedance by distance relays in the presence of Flexible Alternating Current Transmission System (FACTS) devices with series connected branch. Distance relay tripping characteristic itself depends on the power system structural conditions, pre-fault operational conditions, and especially the ground ...

This paper describes the modeling of distance relay using Matlab/Simulink package. SimPowerSystem toolbox was used for detailed modeling of distance relay, transmission line and fault simulation. Inside the modeling, single line to ground (SLG) fault was choose to be the fault type and Mho type distance characteristic was choose to be as the protection scheme. A graphical user interface (GUI) w...

The increase in the line complexity, confi guration and the power transmitted has introduced a number of problems in relation to protection. New techniques have become necessary to tackle these problems. Firstly it has become necessary to see that lines are not unnecessarily disconnected, but at the same time shorter operating times from protective relays are demanded on faulted sections to pre...

Determining the fault location using conventional impedance based distance relay in the presence of FACTS controllers is a challenging task in a transmission line. A new distance protection method is developed to locate the fault in a transmission line compensated with STATCOM with simple calculations. The proposed protection method considers the STATCOM injected/absorbed current to correct the...

Long distance education is an important part during the COVID-19 age. An intelligent privacy protection with higher effect for end users urgent problem in long education. In view of risk disclosure location, social network and trajectory system, this paper deletes location information set to protect user by providing anonymous location. Firstly, divides level networks weighted sensitivity, coll...

Fault ride through compliance as imposed by grid codes prevents undesirable disconnection of renewable plants from the network even during fault. Diversified control schemes adopted in converters associated with such modulate voltage and current output significantly a This varies fault characteristics plant at times thereby affects performance distance relay protecting lines connected to plants...
