“…The corona effect depends on the electric field around the conductor, the conductor diameter and air density [24]. Based on Waters empirical formula, the corona effect cannot have a decreasing impact on a 400 kV TL with a strong conductor having a maximum overvoltage of 600 kV [25]. Therefore, the effect of corona discharge on PWS overvoltage is negligible, and it is not considered in this paper [20].…”

High-speed EMUs (electric multiple-units) frequently pass through the phase-separation zone during operation. Overvoltage generated during the operation of the vehicle-mounted circuit breaker has a long duration and high waveform steepness, which accelerates the service life of the vehicle-mounted equipment and is likely to cause insulation failures. For the above-mentioned problems, the operating overvoltage characteristics of high-speed EMU were obtained by traction substation-catenary-EMUs system (SCES) analysis and experiments, thus deriving the influences of the closed phase angle and the residual magnetism of the vehicle-mounted transformer on operating overvoltage. The results showed that the voltage phase of the catenary significantly affected the operating overvoltage, and the closed switching overvoltage was small at 0–40°, 140–210° and 320–350°. The voltage on the primary side of the vehicle-mounted transformer was 60.78 kV, with the transient impact of high-frequency oscillation overvoltage of 22.71 kV, and an initial period of oscillation of 0.01 ms. Then, the period became longer, and it took 0.5 ms for the high-frequency oscillation from attenuation to disappearance. Finally, a scheme of series reactance suppression devices was proposed to protect vehicle-mounted voltage transformers. This work is to provide data support for the insulation design and system protection of a traction power supply system.

“…Como de forma geral o efeito corona age como um atenuador natural das sobretensões (Cervantes et al (2018)), neste trabalhoé investigada a influência deste fenômeno na atenuação das sobretensões na linha com propriedades de TMO. Pelo conhecimento dos autores, no que diz respeitoà análise do efeito corona em linhas TMO, oúnico trabalho existente na literaturaé apresentado em (Iliceto and Cinieri (1988)).…”

Este trabalho apresenta uma análise da influência do efeito corona na atenuação de sobretensões severas que ocorrem em linhas transmissão de meio comprimento de onda (TMO). Tais sobretensões normalmente são observadas durante a ocorrência de faltas entre fases em certos trechos críticos da linha, e sua elevada magnitude se deve a uma condição de ressonância. Para a representação do efeito corona utilizou-se o modelo de Siliciu, onde a sintonização dos parâmetros foi realizada utilizando algoritmos genéticos. Os resultados obtidos mostram que o efeito corona provoca modificações na condição de ressonância, reduzindo drasticamente a magnitude das máximas sobretensões. As simulações foram realizadas no programa PSCAD/EMTDC.
