Abstract

Managing electrical power usage in a power distribution system. Power usage data indicative of electrical current flow through electrical outlets in the system are collected and displayed for a user. The user may select an outlet and issue a command to control current flow through that outlet. Environmental data may also be collected and displayed. Outlets in different Cabinet Power Distribution Units (CDUs) in different locations may be clustered for reporting and control. A database structure provides a “system” table for data descriptive of the system, a “tower” table for data descriptive of outlets and other elements in the system, an “infeed” table for data descriptive of input electrical power, and an “outlet” table for data descriptive of electrical power flowing through the outlets.
