Distribution Automation

Why
Distribution Automation (DA)?

Most utilities have long wished for real
-
time
monitoring and remote control of
systems
&
assets such as substations, voltage
regulators, capacitor banks, feeder switches,
distribution transformers, and other physical
facilities.


DA systems provide:


Monitoring & control of assets


Identification, isolation,
and
restoration of
service automatically


Reliability &
efficiency

RELIABILITY:

There
have been

five
massive blackouts
over the past 40 years,
but three of which have
occurred in the past
nine years.

EFFICIENCY:

If
the grid were just

5
% more efficient,

the energy
savings
would equate
to
permanently eliminating
the fuel
and
greenhouse
gas emissions from
53


million cars.

Modern challenges : Impact of Distributed
Generation (DG) & Electric Vehicles (EVs)

Impact of Distributed Generation

Large scale interconnection of single
-
phase distributed generation (DG) with
the utility
distribution grid can cause current
unbalances,
resulting in voltage unbalances.

Distributed generation can complicate the regulation of voltage across the length of
distribution feeders.


Impact of Electric Vehicles

Plug
-
in hybrid electric vehicles (PHEVs) are the next big thing in the electric transportation
market. Distribution grids are not typically built to handle a large amount of increased loads.

Similar to DG units, electric vehicles could have a disruptive impact on the electric grid if not
integrated carefully.

Distribution Assets & Challenges Faced in Modernization

The
Multilin

DGCM enables the seamlessly integration of sensors,
assets
and communication into the customers
new or existing
SCADA/DMS/OMS infrastructure
.

Enhancing RMUs (Ring Main Units) and pad mounted switchgear with detection
functionality has its own challenges regarding the mounting of conventional MV
transformers. The
Multilin

DGCM enables the utility to overcome these challenges by
offering
Rogowski

coil and Low Energy Analog (LEA) compatibility for current and voltage
inputs. These features enable utilities in reducing their overall cost of installation and
outage time.


Key Benefits



Real
-
time
load monitoring and profiling of up to 6
feeders (18
individual
phases)



Overcurrent
detection per phase (50, 51) for each
feeder to identify
faulted
circuits and loads approaching
overload levels



Expandable
digital inputs and outputs enable remote
switching of
main
incomers or outgoing switches



Support
of multiple voltage sensors, such as LEA
sensors and PT’s
, for
cost
-
effective power quality
monitoring



Advanced
FlexLogic
TM

engine
to enable automated
switching
schemes



Supports
traditional CT’s and
Rogowski

coils for quick
retrofit
solutions

Monitoring and Control

RMU/Pad Mounted Switchgear

Automation of RMU/pad mounted switchgear with the
Multilin

DGCM
improves grid reliability by reducing outage time.

The challenge faced in underground networks is the quick identification of faults.
Deployment of the
Multilin

DGCM at strategic locations along cable paths enables faster
fault detection as well as early warning signals in case of overload.

Monitoring and Control

Cable in Vaults

Key Benefits



Compact, cost
-
effective fault detector for underground
cable
networks



Rogowski

coil option to enable retrofit installation in
space
-
limited
locations
and to reduce the need for
outages



Early warning and fault detection per phase (50, 51)
for each feeder
to
reduce fault location and feeder
downtime



Multiple communication (cellular and radio) and
protocol options for
easy
integration into DMS and
SCADA systems

Using the
Multilin

DGCM on cables enables faster fault detection and
isolation, reducing outages and crew deployment time.

Most consumer substations and indoor/outdoor LV systems lack asset
monitoring
and control. The
Multilin

DGCM can be used to effectively
monitor
power quality, as well as control, when necessary.
Rogowski

coil
support provides current sensing in hard
-
to
-
find spaces and allows

for modifications without an actual outage. The provision of overcurrent
detection
provides a vital
warning signal well in advance of an actual
failure
.

Monitoring and Control

Consumer Substation, LV Systems

Key Benefits


Real
-
time load and energy monitoring and profiling of up to
6 feeders (18 individual phases)



Quick retrofit installation especially in tight spaces through
Rogowski

coil current sensors or traditional CT’s



Cost
-
effective energy monitoring through direct voltage
measurements up to 400V or via LEA voltage sensors



Ability to compensate for amplitude and phase shifting
associated with different sensor types



Identification of faulted circuits and loads approaching
overload levels through overcurrent detection per phase (50,
51) for each feeder



Per feeder energy monitoring and logging to help identify
locations of theft detection



Unsolicited messaging to ensure faster response time to
SCADA/DMS systems, making utilities aware of impending
abnormalities

Monitoring at key LV consumer substations with the
Multilin

DGCM can
help in faster fault isolation and energy theft detection.

Transformers may be loaded to their maximum capacity without the utility even realizing it ,
resulting in reduced transformer life. The
Multilin

DGCM enables the monitoring of
transformer conditions, identifying transformers likely to fail. Keeping the utility updated of
changing load demands enables proper planning for current peak loads and future
demand.

Real
-

flow studies and planning



Multiple communication (cellular, radio) and protocol
options to ensure compatibility with existing
infrastructure

Transformer monitoring with the
Multilin

DGCM enables overload
identification, which is key for load planning and asset management.

** Available by end of Q3 2013

The
most difficult task for
the
utility engineer is to predict the
future reliability
of the
transformer
fleet, and to
replace
each one the day
before it fails. Meeting
the
growing
demand of the grid
while
maintaining system
reliability with this
aging fleet
will require significant changes
in the way the utility operates
and cares for its transformers.

Total
distribution
transformers in
developed
countries:

-
~55
% are
in utility

-
41
% are used in industry, commerce
and mining

-
~3
% in
transport

Utility
transformers are predominantly (about
90
%) of
the liquid
-
immersed (liquid
-
insulated) type.
