Power management with powermanager
For power and plant monitoring, Siemens offers the powermanager software. Together with
SENTRON protection devices such as 3VA, 3WL and PAC measuring devices as well as
non-Siemens devices, powermanager provides a power monitoring system for reducing
energy costs and increasing energy availability.
powermanager acquires the measured variables that are needed to optimize power
consumption and so reduce costs. These variables not only include energy and power
values, but also electrical parameters such as current, voltage, or power factor. Not only is
this system able to display values, but also to monitor and archive them for later analysis. In
addition, the load monitoring function is capable of monitoring a specified setpoint and
making recommendations as to which loads should be connected and disconnected.
Identifying savings potential
The power monitoring software has been tested by the TÜV Rheinland for its suitability to
support an energy management system in accordance with ISO 50001.
Functionality and user-friendliness
The salient features and functions of the power monitoring software are as follows:
● Good scalability
● Enhanced report templates
● Response plans
● Mass parameterization
● Virtual measuring points for computing customer-specific parameters
● Load monitoring function for monitoring specified power limits for freely definable time
periods
● Switching recommendations in the event of limit violations
● Remote control of circuit breakers
