Hitachi Introduces Railway Power Analysis Service

Hitachi announced that it will begin offering its “Railway Power Analysis Service” on August 28 to support railway operators’ energy management. In recent years, the railway industry has faced urgent challenges in addressing climate change, and rising transportation costs due to rising energy prices have also become a challenge. Against this backdrop, there is a need to realize economically sustainable transportation operations while reducing environmental impact, making improvements to railway power operations essential. The Railway Power Analysis Service addresses these challenges by comprehensively analyzing railway operators’ vehicle and equipment information, as well as actual operation and power transmission data, using Hitachi’s proprietary railway system integrated simulator to optimize power operations and achieve both reduced environmental impact and cost savings.

Prior to the service launch, Hitachi conducted trials with several railway operators and confirmed its effectiveness in reducing instantaneous maximum power consumption during peak periods and overall power consumption. In particular, the service claims to reduce regenerative braking lapses, a phenomenon in which regenerative power generated when a train stops or slows down is not consumed or stored, resulting in reduced braking force, by approximately 70%. The “Railway Power Analysis Service” visualizes issues through comprehensive analysis of on-site data, and by using a railway system integrated simulator, it is possible to identify the causes of potential issues that are difficult to detect from individual events.

Furthermore, since it allows for comprehensive and detailed analysis of the entire line without relying on vehicle operation record data, even when data obtainable from vehicles is limited, it is possible to analyze the entire line by utilizing existing non-vehicle data such as train schedules to supplement the gaps. In addition, by leveraging the Hitachi Group’s expertise in various railway infrastructure fields, it provides one-stop support for railway operators in resolving issues, from verifying improvements based on analysis results to implementing measures. 日立 will continue to support railway operators in continuously improving their facilities and operations, aiming to expand its functionality, including enhancing its analytical environment, developing optimal operational plans through integration with existing systems, and real-time energy control according to the situation.
