Supporting higher efficiency and round-the-clock reliable operation of various power distribution devices through intuitive monitoring and sound maintenance

As a total solution for supervisory control of power distribution equipment,

MELSAS-S realizes reliable control during normal operation, reduced

maintenance and support for automatic measures in the event of accidents

and power interruptions.

Mitsubishi Electric Substation Administrative System : MELSAS-S

Reduced operating costs and increased energy savings via monitoring and control of power-factor and power demand

Greatly reduced wiring costs (including costs of materials, testing and installation) through use of a transmission system

More e�cient daily/regular inspections and restoration after accidents

Contributes to reducted lifecycle costs of power distribution equipment

Greatly enhances system reliability through use of optical-�ber signal transmission lines

Improved visibility and operability of monitoring display screens

Redundant systems can be configured through use of various devices to create a system suited to the operational and environmental conditions.

System operation can be continued without failure even when one of CPU's is in failure or stopped for maintenance.

When demand exceeds the level-two alarm line, after a set amount of time, the input power is accumulated, and loads are cut-off starting with those of lower priority.

Current reactive power (VAR) is measured, and capacitors are used to automatically regulate the power-factor to close to 100% (reactive power close to 0) through controlling the on/off operation of capacitor switches in a cyclic manner.

Smooth capacitor use is possible by cyclically controlling the on/off operations of capacitor switches (Mode 1 in figure on right).

The MELSAS-S monitoring computer can be used to set the reactive power upper limit on the advancing side (cut-off using capacitor switches) and the lower limit on the delay side (turn on/off using capacitor switches).

Procedures up to output point terminal block exposure are included in installation work covered by Mitsubishi Electric. Installation work performed by the customer includes selection of controller priority and items to be controlled as well as external line cable installation.

Power should be turned on again manually when demand returns to under the level-two alarm line.

Cutoff signal is output after level-two demand alarm is issued continuously for a set amount of time (priority 1 only).Subsequenrly, cutoff every minute (priority 2 to 16).
