Load Management
Critical to any load management system is the
ability to track consumption and quickly respond to peak loads,
eliminating the need to purchase power on the open market.
Telemetric devices can assist with:
- Load Shedding
- Back-up Generation
Load Shedding:
The ability to shed and restore
loads provides an essential part of the Demand Side Management
process. Discretionary load switching, or customer load management,
involves the direct control of loads at individual customer sites
from a remote location. Control may be exercised for the purpose
of overall system peak load reduction or to reduce the load on
a particular substation or feeder. The Telemetric solution has
been used to shed non-essential industrial and agricultural loads.
To shed load effectively, system operators
must know when to interrupt, and when not to. Unnecessarily
interrupting can cost money and customer goodwill, and not shedding
during a peak load can cost thousands of dollars per minute
when power must be purchased on the open market. Telemetric
devices can read energy usage from the utility and large customers.
As a peak approaches, the Telemetric system automatically sheds
non-essential loads.
The digital inputs and outputs of
the Telemetric unit can be used both for monitoring and control
of the load management process, including peak-load shedding,
cold load pickup and load reconfiguration.
Back-up Generation:
The Telemetric MicroRTU can be used to remotely monitor and control
a standby generator. Up to six digital inputs are available to
monitor the status of the generator and other contact closure
inputs. The built-in Single Phase Voltage Monitor provides real
time feedback of actual voltages.
Telemetric devices can remotely operate
small to medium sized generators to counteract consumption during
heavy power usage. When the peak shaving generators have successfully
been turned on, the device sends an acknowledgement to system
operators. Multiple generators can be grouped together so one
single command turns on all generators, rather than relying
on cumbersome and time consuming dial up connections where each
generator must be turned on individually. When operating at
peak capacity, each extra minute that the generators are on
can save a substantial amount of money by decreasing the amount
of power that must be purchased.
Telemetric Solution Benefits:
Telemetric MicroRTUs offer several functional advantages
over other products:
- In many cases, a Telemetric load management
solution pays for itself within a year.
- System reliability is improved by a direct, positive confirmation
that a command was carried out
- The cellular data network coverage exceeds that of any other
wireless communication option in North America.
- The internal cellular radio module is mobile and can "roam"
anywhere in the North American cellular area with no need to purchase
local cellular accounts.
Six digital outputs can be used for
directly controlling a wide range of customer equipment. The MicroRTU's
two 120VAC (or 240) VAC outputs can be individually configured
as:
- momentary control signals with programmable durations to match
the startup time requirements of controlled equipment, or
- as continuous ON/OFF control signals.
The
momentary output signals can be user configured in 0.1 second
increments from 0.1 second to 241 hours. The solid state 10
Amp output relays (a recommended option) feature zero voltage
switching and are rated from 24 - 280 VAC, with load current
of 0.04 - 10 Amps RMS and a 1 cycle surge current of 120 Amps
peak.
Four
analog inputs can also be configured to monitor a variety of
conditions including voltage, current, temperature, pressure,
levels, flow or humidity, using 0-5 VDC, 0-1 mA, or 4-20 mA
