Regenerative energy flow. For significant energy savings, S-EIV feeds excess power to electrical equipment in station buildings when power supplied by trains during braking cannot be fully utilized by other trains.
An inverter is a form of energy-saving device that effectively regulates motor speed to stop air conditioners from operating inefficiently. When the room temperature rises over the specified value, the air conditioner cools, and when it drops below the set temperature, the air conditioner heats.
The global station energy saving inverter market accounted for $XX Billion in 2021 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2022 to 2030.
A new integrated Station Energy Saving Inverter (S-EIV) with 400V AC-output has been introduced by Mitsubishi Electric Corporation for converting excess regenerative energy from train braking into AC electricity for station facilities. Even in railway stations with high load requirements for 400V power distribution circuits, the new 400V AC SEIV offers simple installations and more energy-efficient operations.
Additionally, the business disclosed that the new S-EIV would be put in Tokyo Metro Co. Ltd. train stations that serve the city.With the same dimensions as its 200V AC predecessor, the new S-EIV produces 400V AC output. Additionally, to lessen harmonics in AC output, its novel multipurpose step-up transformer also serves as a filter reactor. Variety is made possible by front access for simple cabling and maintenance alternatives for installation.
The addition of monitoring and protective features has increased reliability. Along with the enclosure’s dustproof, splash-resistant, and rust-resistant design, a new earth-fault detection circuit quickly pinpoints unexpected current flows to the earth via the unit’s enclosure due to deteriorated or damaged insulation, ensuring safe grid interconnection and durability for outdoor use. System stability and ease of maintenance are influenced by improved monitoring of main circuit devices and grid voltage.
