Key Technologies for Electromagnetic Transient Calculation and Protection in Power Systems
“电力系统电磁暂态计算及防护关键技术”

With the large-scale and high-proportion integration of wind power, photovoltaics, and other new energy sources into the grid—using power electronic devices as their core interfaces—along with the widespread application of flexible HVDC transmission and energy storage systems, the dynamic characteristics of the power system have undergone fundamental changes. Its electromagnetic transient processes now exhibit unprecedented complexity and strong coupling. The increase in device switching frequencies and the complexity of system topologies have led to increasingly prominent issues of wide-frequency-band electromagnetic interference. This not only seriously threatens the reliable operation of secondary equipment such as measurement, protection, and control devices, but the induced electromagnetic transient processes may also directly trigger or exacerbate system-level faults.
Simultaneously, the fault mechanisms in new-type power systems differ significantly from those in traditional systems, featuring complex fault current characteristics and fast propagation speeds. This poses significant challenges for the rapid and accurate detection, safe isolation, and system recovery of faults. As the first line of defense for system security, relay protection, fault control, and system restoration strategies must fully consider and adapt to this complex electromagnetic transient environment. Therefore, in-depth research on electromagnetic transient computation, precise sensing, active protection, and coordinated recovery technologies for new-type power systems has become key to breaking through current system security bottlenecks and supporting the high-quality development of new-type power systems.

This special issue aims to gather the latest research achievements in this field, focusing on core topics including but not limited to:

1. 1.Wide-frequency electromagnetic transient computation and simulation technologies for new-type power systems.
2. 2.Reliability of sensing and measurement equipment in complex electromagnetic environments.
3. 3.Fault early warning, diagnosis, and location technologies for new-type power systems.
4. 4.Fast fault clearance technology coordinating electromagnetic interference protection and relay protection.
5. 5.Fault current limitation and system self-recovery control strategies for power-electronized systems.
6. 6.Electromagnetic transient effect analysis and protection of critical power equipment.
