However, since the effects of lightning surges due to common grounding is not organized quantitatively in an environment in which high-voltage (power supply) systems and low-voltage (signaling and telecommunication) systems are mixed, as with the case with railways, the study of common grounding of railway systems is not in progress at present. In this paper, we propose a method for calculating optimal grounding systems of railway telecommunication systems in terms of lightning surges by combining the calculation using the analysis model for railway telecommunication systems and mathematical optimization techniques.本誌: 電気学会論文誌B（電力・エネルギー部門誌） Vol.137 No.11 （2017） 特集：IWHV2016 & JK2016本誌掲載ページ: 717-723 p原稿種別: 論文／英語電子版へのリンク: https://www.jstage.jst.go.jp/article/ieejpes/137/11/137_717/_article/-char/ja/ Show more
