Enhancing Distance Protection of Long Transmission Lines Compensated With TCSC and Connected With Wind Power

Effects of CT and VT Connection Point on Distance Protection of Transmission Lines with FACTS Devices

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 ...

Distance Protection of Series-Compensated Lines: Problems and Solutions

restoration process improvement in power systems with series compensated transmission lines

this paper investigates the islands formation in initial stages of restoration process in blackout condition and studies the impacts of islands number variation on the process execution. in addition, a method is proposed to determining each island optimal boundaries. then the effects of transmission lines thyistor controlled series compensators (tcsc) to facilitate restoration process and impro...

Adaptive ground distance protection for UPFC compensated transmission lines: A formulation considering the fault resistance effect

This paper presents a mathematical deterministic adaptive distance protection formulation for UPFC compensated transmission lines. The proposed formulation is developed using a phase component approach and considers and compensates for various UPFC operation conditions and non-zero fault resistances. The proposed methodology is completely adaptive and independent of system characteristics (such...
