Theoretical Analysis on Subharmonic Resonance Overvoltage

2010 International Conference on Electrical and Control Engineering, 2010
With the continue increases in power system voltage level, more and more complex wiring has resulted in the more frequently occurrence of the subharmonic resonance. To address this issue, this paper deduces the mathematical expression of the subharmonic resonance and uses mathematical analysis method to solve the nonlinear differential equations based ...

Influence assesment of autotransformer remanent flux on resonance overvoltage

open access: yes, 2020
Abnormal resonance overvoltagesoccur due to the emergence of non-sinusoidal modes of bulk electrical networks. The considered type of overvoltage refers to durable internal overvoltages, which have characteristics that can exceed the maximum permissible magnitude with a certain correlation of the values of the parameters of the extra high voltage power

Research On Ferromagnetic Resonance Overvoltage Based On Station Service Voltage Transformers

2020 IEEE International Conference on High Voltage Engineering and Application (ICHVE), 2020
Station Service Voltage Transformers (SSVT) combines the operating characteristics of power transformers and the design characteristics of measuring voltage transformers. Due to its lower initial cost and higher power supply reliability, its applications have been extended beyond that of auxiliary power. During transient events in the network caused by

Protecting PFC Capacitors from Overvoltage Caused by Harmonics and System Resonance Using High Temperature Superconducting Reactors

open access: yesIEEE Transactions on Applied Superconductivity, 2019
Shunt capacitors are deployed for power factor correction (PFC) to reduce the load reactive power and to provide voltage support. Nonlinear loads, such as variable speed drives, can inject harmonics into the network.

Research of Resonant Overvoltages in Power Plant Auxiliary Circuits

2021 IEEE Conference of Russian Young Researchers in Electrical and Electronic Engineering (ElConRus), 2021
Current-limiting reactors and transformers destructions in auxiliary network of 13.8 kV medium voltage (MV) took place at the 2488 MW HPP during operational switching on the adjacent 500 kV network. Arc overlap traces were found on the reactors and auxiliary transformers bushing (ATB).
