1. Yurikamome Power Management System Update
Hitachi received an order for a power management system update from rail transport operator Yurikamome Inc. The completed equipment was delivered to the site after production finished in March 2019. The equipment is now being tested on-site in preparation for the start of operation planned for September 2020.
The Tokyo Waterfront New Transit Waterfront Line (known informally as the Yurikamome Line) is a new rail line providing unmanned service between central Tokyo and Tokyo waterfront area. Its power management system provides monitoring and control for power conversion and distribution equipment at 22 locations. It is composed of components such as monitoring/operation consoles, monitoring/control servers, remote monitoring/control equipment, remote control slave stations, and interface panels. The main features are as follows:
- The servers, remote control slave stations, and interface panels were given a duplex configuration to improve reliability and maintainability.
- The grid display panels used for the monitoring work done by the command staff were changed from a mosaic panel hardware configuration to large-screen liquid-crystal display types, enabling detailed power grid displays and improving readability and maintainability.
- The efficiency of command work was improved by adding a virtual label function that lets users add whatever information they want to grid screens, and by improving regularly scheduled operation functions.
