Traditional Automatic Train Operation (ATO) algorithms are generally designed based on single-train operation with the objective of improving the speed profile of a single train to reduce mechanical energy consumed under operational constraints. For many electrified rail transit systems where energy cost is calculated at the substation level, minimizing energy consumption needs to consider the ...

1. Introduction Mitsubishi Electric offers solutions centered on security , under the brand name DIGUARD, for various customer problems in buildings, factories, public facilities , and so on. As an example, this paper describes the development of an energy saving system that coordinates security and lighting equipment. In recent years, as evidenced by revisions to the Energy Saving Law and Toky...

Power cables that have sheaths, usually lead, and are manufactured with bitumen impregnated hessian which degrades over time, act as long grounding electrodes or inject fault current directly into the surrounding soil. As a consequence of this, the MV lines made of this type of cable spontaneously form a very large and complex grounding system around the high-voltage/medium-voltage (HV/MV) dist...

Introduction: Recent industrial developments in human societies have caused rapid advancements in technologies of production and distribution of electricity, which in turn result in enhancement of power networks and utilization of high voltages. These networks and the high voltages in transfer lines cause the exposure to electric and magnetic fields. In this study, the situation regarding the m...

Transformer is the power equipment of power system core. Intelligent monitoring and operation of transformer can not only monitor the full range of the transformer, the realization of state evaluation, it should be required repair, maintenance required good, but also on the latent fault early diagnosis and prediction. Research on transformer intelligent monitoring and operating technology of sa...

One of transient phenomenon that causes the mal-operation of the power transformer differential protection during the energization of a loaded power transformer is the ultra-saturation phenomenon. In this paper, a new model for investigating the ultra-saturation phenomenon during the energization of a loaded power transformer is presented and its effect on the differential protection of the pow...

Abstract The intelligent delivery robot for substation maintenance is a kind of equipment power system, which can assist or even replace the artificial to carry in substation. It has important theoretical significance and practical application value automation operation management Substation autonomous navigation motion control key promote its application, based on this, this paper proposes veh...

This paper proposes a new backup protection scheme, named coordinated backup protection (CBP) scheme, for distribution networks containing distributed generation. The proposed protection scheme takes into account the issues faced by traditional backup protection, such as difficulty in setting parameters and complex cooperation, and considers the features of distribution networks, such as change...
