“…Harmonics are a common problem for electrified railways [23]. The AC-DC electric locomotive harmonics are mainly third, fifth, seventh, and so on [24]. In this model, four typical operating conditions (third, fifth, seventh and ninth harmonics) were selected.…”

An AC electrified railway can interfere significantly with parallel underground pipelines in a public transportation corridor. Such interference may threaten the long-term transportation and the operational safety of the pipelines. Therefore, this paper presents a mathematical model to illustrate the electromagnetic coupling between an AC electrified railway and nearby parallel underground pipelines. As the basis of the engineering calculation, an integration simulation model based on CDEGS software, which included an electrified railway and pipeline system, was built and its correctness was validated by comparing it with a mathematical model. Also, the effects of electric traction load parameters, pipeline parameters, and soil structure parameters were analyzed, the results of which demonstrate the distribution characteristics of AC interference on parallel underground pipelines. Using a real case in China as an example, protection measures were introduced to decrease coupling interference and their effectiveness was verified by simulation calculations and field measurements.

Este artículo propone una metodología para el análisis de calidad de potencia en instalaciones eléctricas industriales. Inicialmente se realiza una medición multipunto, después se identifican y analizan los fenómenos que más afectan a la industria, luego se modela y ajusta el sistema al comportamiento real, y se proponen y simulan algunas soluciones. Posteriormente, se selecciona un caso de estudio y se realiza el estudio de calidad de potencia a partir de la metodología propuesta y según los parámetros de la norma NTC 5001. Finalmente, se establecen las ventajas del uso de la medición multipunto y el modelado en estudios de calidad de potencia.

“…The other method is to install passive high-pass filter (HPF) in the TSS or sectioning post, such as first-, second-, thirdorder and C-type, which is a simple, reliable, and easy-toimplement approach to effectively filter out high-frequency harmonics and address resonance issues [22][23][24]. Nevertheless, one-and two-order HPFs have large fundamental losses due to the series resistor of the filter branch, especially first-order HPF [22].…”

“…The third-order HPF exhibits very small fundamental loss, but it will introduce an additional parallel resonance point below the original resonance point. The C-type HPF described in [23,24] shows better comprehensive performance and almost has no fundamental loss, but it is sensitive to parameter variation.…”

To reveal the penetration characteristics of high-frequency harmonics of the traction network to the three-phase 380 V power system in the traction substation (TSS), the harmonic equivalent circuit model and harmonic penetration mathematical model of the two-phase to three-phase Scott-T transformer are established. Through the power quality measurement and harmonic analysis, the results indicate that the high-frequency harmonics in the traction network will severely penetrate the three-phase 380 V power system, which will cause almost the same degree of harmonic distortion, verifying the correctness of the harmonic penetration model. To filter high-frequency harmonics in TSS, a novel structure of high-pass filter (HPF) is proposed that features with high-pass characteristic at high frequencies while highimpedance at fundamental frequency. Furthermore, a set of three-phase experimental device is developed, and a long-term filtering experiment in the TSS is performed. The experimental results show that the novel HPF experimental device can effectively filter out high-frequency harmonics of the three-phase 380 V power system, and have almost no loss and reactive power. The feasibility and effectiveness of the suppression scheme based on the novel HPF are verified.
