TEPCO has accomplished stable and reliable power system to achieve high quality
power supply. To realize the well-balance performance, TEPCO improves protection
performance, develops various protection systems and uses appropriate controller
etc.
TEPCO adopts a "Distribution Automation System (DAS)" for distribution
network system. Line switches set on distribution networks are to be controlled
remotely from the sales office (control center) by DAS, therefore, distribution
network system can be operated effectively and in case of fault occurrence,
restoration power is immediately supplied to, healthy section, and away from
the faulted section. If distribution network configuration is planned appropriately,
distribution system reliability is definitely improved.

Automation System" by using our past experiences and achievements for
higher reliability realization.
