Improvement of Distance Protection with SVM on PV-Fed Transmission Lines in Infeed Conditions
Energies, 2023 Photovoltaic (PV) power plants have comparatively weak infeed characteristics, unlike conventional synchronous generators. The controllability of grid-connected inverters and the limited overcurrent capability of power electronic devices means that the ...

Fault Studies and Distance Protection of Transmission Lines Connected to DFIG-Based Wind Farms
Applied Sciences, 2018 Doubly fed induction generator (DFIG) based wind farms are being increasingly integrated into power grids with transmission lines, and distance protection is usually used as either the main or the backup protection for the transmission line.

Impact of inverter-based resources on transmission line relaying -part II: power swing protection
Frontiers in Electronics, 2023 The power swing characteristic of transmission lines (TLs) can be affected by the large-scale integration of inverter-based resources (IBRs), resulting in the maloperation of the legacy power swing blocking (PSB) and out-of-step tripping (OST) functions.

A Setting Optimization Strategy for Distance Protection Ⅱ after Connection of Synchronous Condensers
Zhongguo dianli, 2022 The large-scale access of synchronous condensers (SCs) to the power grid will reduce the protection range of the distance protection section Ⅱ, and reasonable optimization of the protection setting is a feasible way to solve this problem. For this reason,
