Power Management/301, Version 1

DESCRIPTION:
The Power Managementl301 ,applications software
monitors electrical power usage and shuts off, or
throttles back, selected equipment to reduce peak
power requirements and reduce total energy consumption. Flexible operation is provided by a large
base of user-specified parameters.

English-like operator commands are used on the operator terminal for dialogue with the system. Meter
and load status reports are available on request or on
a scheduled basis. Historical data can be recorded on
cassette for later play-back.
The system determines power usage levels through
connections to the pwer metering equipment. Based
on actual usage levels, power levels are forecasted
and compared with a desired target level. Up to 96
load control outputs are shut off depending on the
difference between target and forecasted demand
values. Equipment is shut down according to userspecified priorities and will be turned on again after a
specified off-time. Up to 6 different off-times can be
specifed during the 24 hour day. Equipment will not
be shut down again before a cycle time has passed In
order to prevent excessive on/off cycling.
If the system forecasts that the pre-specified target
demand value will be exceeded despite the maximum
effort of the system to shed all available loads, a
warning message will alert the operator to permit
manual control of loads.

Once the system operating parameters have been entered or altered, a command can save the parameters
on cassette. Several sets of parameters can be set up
and saved. Later. the parameters can be reloaded
into the system for quicker system start-up without
re-enterlng the parameters.

A simulation mode provides a software Simulated
power meter. Repeatable power peaks are generated
by the power meter and supplied to the system control programs. Parameters such as off-times and cycle-times can be "tried-out" in simulation mode. Reports can be printed or data recorded Just as with
actual power meter connections.
