High Voltage, EarlyView.ABSTRACT This paper investigates the generation mechanism of quasi‐power‐frequency resonant overvoltage triggered by multiple lightning strikes in high‐voltage alternating current (HVAC) systems equipped with shunt reactors. Based on field measurements from a 500 kV AC system, equivalent and simplified circuit models have been established to analyse ...

High Voltage, EarlyView.ABSTRACT To effectively suppress transient overvoltages in HVDC systems, the design and experimental validation of a multi‐module series controllable arrester are presented. The voltage‐limiting performance, series voltage equalisation capability, and robustness under fault conditions in high‐voltage scenarios require further research.

Assessment of Temporary Overvoltages During Network Lines Re-Energization
Advances in Electrical and Electronic Engineering, 2016 Power system blackouts are very infrequent, but they have a Brobdingnagian effect on the system performance and devices. The present research work offers remarkable techniques for the assessment of temporary overvoltages all through the re-energization of network lines.

Engineering Reports, Volume 8, Issue 6, June 2026.Due to complex wind farm conditions, a coordinated control system was designed. It manages DC power surges during AC faults by temporarily storing excess energy and regulating voltages. This strategy optimizes unbalanced power and enables effective fault recovery, resulting in minimal voltage fluctuations and superior performance.
