Estimation of New Weighted Controlled Switching Overvoltage by RBFN Model [PDF]
Journal of Operation and Automation in Power Engineering, 2020 Mitigating switching overvoltages (SOVs) and conducting well-suited insulation coordination for handling stresses are very important in UHV transmission Lines. The best strategy in the absence of arresters is controlled switching (CS). Although elaborate

Research on Inrush Current Suppression of Transformer Based on Changeable Closing Angle
Zhongguo dianli, 2022 The transformer no-load closing inrush current may cause safety problems in power grid, and the controlled switching technology with fixed target angle still has room for improvement in suppressing inrush current. A transformer inrush current suppression

Controller architectures for switching [PDF]
2009 American Control Conference, 2009 This paper investigate different controller architectures in connection with controller switching. The controller switching is derived by using the Youla-Jabr-Bongiorno-Kucera (YJBK) parameterization. A number of different architectures for the implementation of the YJBK parameterization are described and applied in connection with controller switching.

THE RESONANT OVERVOLTAGE IN NON-SINUSOIDAL MODE OF MAIN ELECTRIC NETWORK
Electrical engineering & Electromechanics, 2018 Purpose. The resonant overvoltage arises in main electrical networks as a result of random coincidence of some parameters of circuit and its mode and it may exist for a relatively long time.

A remote control for switching [PDF]
Nature Chemical Biology, 2018 Calcium channels are crucial regulators of a broad range of biological processes. A photoswitchable chemical probe allows the opening and closing of these channels with unprecedented temporal resolution, providing new opportunities to study calcium-dependent signaling pathways in real time.
