Special Session I

With the rapid development of new-type power systems and the increasing penetration of renewable energy, power electronic equipment has been widely deployed to support renewable energy integration, long-distance transmission, and flexible system control. As the first line of defense for ensuring the safe and stable operation of power systems, relay protection plays a critical role in modern grids.
However, with the profound evolution of system structures and operating modes, as well as the growing complexity of interactions among generation, networks, and loads, relay protection in new-type power systems is facing significant challenges, including:
(1) increasingly complex and highly coupled fault mechanisms;
(2) insufficient reliability and sensitivity of existing protection principles;
(3) inadequate consideration of fault control characteristics in current protection schemes;
(4) the need for further improvement in fault location and system restoration performance.
Therefore, relay protection has become one of the core and critical technologies that must be advanced for the development of new-type power systems.

随着新型电力系统的快速发展及新能源装机比例的持续提升，电力电子装备在可再生能源并网、远距离输电及系统柔性调控中的应用规模不断扩大。作为保障电力系统安全稳定运行的第一道防线，继电保护在新型电力系统中发挥着至关重要的作用。然而，随着系统结构与运行形态的深刻变革，以及电源、电网与负荷特性的高度复杂化，传统继电保护理论与技术面临一系列新的挑战，主要体现在：
（1）故障特征机理呈现强耦合与复杂演化特性；
（2）现有保护原理在可靠性与灵敏性方面存在不足；
（3）传统保护方法未能充分考虑新型电力系统的故障控制特性；
（4）故障定位与故障恢复能力仍有待提升。
因此，继电保护已成为新型电力系统亟需突破的核心关键技术之一。
