Summary: This paper calculates the lightning current shunt characteristics in multi-tower scenarios and analyzes the current dispersion process among multi-tower grounding grids and pipelines under different soil resistivities. The protective effect of drain wire and forced commutation on pipeline overvoltage is compared. The research findings show that the pipeline overvoltage is significantly larger when the lightning current passes through multi-tower grounding grids compared to a single tower.

Summary: Transmission lines of grid-connected solar power plants can be damaged by lightning strikes. The surge voltages in the primary winding of the transformer were measured in a simulation by injecting lightning impulses into the transmission line. The results showed that different waveform characteristics and various soil parameters, cable length, and cross sectional area could affect the surge voltages.

Summary: In this paper, a lightning strike identification model based on morphological fractal theory is constructed. A simulation model of lightning-struck tractive network faults is developed to study the influence of the structure of the all-parallel AT tractive network on the waveform characteristics. The fault analysis of lightning strike signals is carried out based on mathematical morphology, and the classification effects of single- and multi-scale fractal dimensions of voltage and current waveforms are compared based on fractal theory. Moreover, a neural network framework is employed to establish a lightning-strike identification model, achieving an accuracy of more than 95% in identifying lightning strike faults.

Summary: This study develops a new relaying scheme for the complete protection of transmission line based on only voltage data. Fault detection and classification are obtained from the fundamental component of the voltage signal, while fault location is determined using the magnitude of the positive sequence component. The proposed scheme eliminates the need for data synchronization and the error caused by current transformers, and can locate all types of faults.

Summary: Inrush current generated during transformer energization can negatively impact transformer safety and the effectiveness of relay protection, leading to possible grid security concerns. A reduction strategy combining prefluxing and controlled switching technology can effectively lower inrush current magnitude. This approach enhances system reliability by addressing the issues arising from inrush current generation mechanisms.

Summary: This paper proposes a new distance protection approach to address the issue of malfunction of conventional methods under reverse fault-induced CT saturation in the breaker-and-a-half configuration. The proposed approach combines the values of incomplete differential current, operation voltage, and current harmonic content to ensure reliable distance protection in various fault conditions. The approach is verified through theoretical analysis, dynamic simulation testing, and field operation, proving its effectiveness in preventing unnecessary operation during CT saturation and reliable operation in different fault scenarios.
