Analysis of Switching Overvoltage and Suppression Measures in UHV Transmission Lines

Canadian Journal of Electrical and Computer Engineering, 2019
As the ultrahigh-voltage (UHV) projects are rapidly developing, it is necessary to investigate the problems involved in overvoltage and insulation, thereby providing a technical basis for future UHV projects. The switching overvoltage of closing no-load lines was simulated and analyzed here using two kinds of typical UHV network structures: the power ...

Temporary overvoltage suppression in half-wavelength transmission lines during asymmetric faults

Electric Power Systems Research, 2020
Abstract This paper approaches the principal electric characteristics of half-wavelength transmission lines and possible voltage transients resulted from asymmetric faults. Although this non-conventional AC transmission technique presents some attractive advances for electric power transmission through long distances, when compared to the well ...

Study on Submarine Cable Opening Overvoltage Modeling and Its Suppression Technology

2019 IEEE 3rd Advanced Information Management, Communicates, Electronic and Automation Control Conference (IMCEC), 2019
Capacitive components of the power system are energy storage components, when the operation or failure to change its working state, there will be a transition process. During the transition, since the power supply continues to supply energy, and the magnetic energy stored in the inductor translates into a capacitance in the form of electrostatic field ...

Research on Overvoltage Suppression of the Battery Discharging in Electromagnetic Launch

2019 22nd International Conference on Electrical Machines and Systems (ICEMS), 2019
This paper introduces a discharging circuit of batteries in hybrid energy storage system for electromagnetic launch. The main switch, integrated gate bipolar thyristor(IGBT), has a high overvoltage at turn-off time in the discharging process. This paper analyzes the causes of the overvoltage based on the circuit structure and the timing discharging ...
