Abstract: This paper explores the relay protection of the power grid with large-scale wind power access across the globe. First, the amplitude and attenuation characteristics of short circuit current in different types of wind turbines are analyzed, as well as the contributing factors to. To address the critical issue of low reliability caused by fault impacts in large-scale wind farms transmitting power over long distances via flexible DC transmission systems, this study proposes a collaborative solution. First, a new protection scheme integrating variable quantity differential. able sources such as wind and solar. These clean energy sources, connected through inverters and flexible transmission systems, are transforming traditional grids based on synchronous generators into more flexibl cant challenges to system stability. Nowhere is that clearer than in the challenge to. Working Group C25 of the Power System Relaying and Control (PSRC) Committee wrote a report to document up-to-date relay protection and coordination practices for WEPs. The relays are tested in a Hardware-In-the-Loop environment and the strengths and weaknesses of these functions are determined.
