Power control systems

Monitoring and controlPower control systems

Power control command systems for Railway Transportation System are strictly required high reliability and real-time performance to support relaiable traction power supply. We build various types of power control systems with high reliability and maintenability that meets the long-term maintenance requirements. These features are implemented by combining our Power control command system and in-house-made industrial components. In particular, we have abundant track records of supplying Power control command system that incorporates our know-hows of Notification by cell-phone system, Power control support function and Simulation function.

Functional examples of the power command system

Automatic control
Installed functions include: + automatic execution of planned power outage such as scheduled power shutdown + automatic re-closing + automatic cancellation of the crossing power distribution.
Notification by cell phones
By notifying the work status from the project site by cell phone (site arrival, work commencement, work completion, leaving the site), the system gets the update of the work progress on site, perform the timely interlock of related power equipment while the site work, and contributes to ensure safety.
Fault recovery support
By showing the fault detection and supporting informatino, it supports the fault recovery by remote monitoring staff.
Operation training
Practical training is performed by various types of related simulation programs and the function of fault replicating funciton based on simulations.
Smart device ready
We could provide the latest user interface to the smart devices such as tablet by the smart visualization of the system without sacrificing the real time funtion of the remote monotoring control system.
