<b>Grid Enterprise Manager (GEM)</b> is an advanced application platform that operates in
conjunction with the FrameWorx data acquisition platform to provide the Operators and Engineers of
Electrical Utilities with actionable data from IEDs located in Substations across the grid. GEM
establishes and maintains a centralized database of IED operational and non-operational data, plus a
set of core functions and advanced application that address critical use cases for operational
performance and regulatory compliance.

<div class="col-xs-12">
<p>
FrameWorx Data Collectors continuously monitor IEDs across
the grid for fault, disturbances and other events related to grid
performance. When detected, relevant data is uploaded from
the Substations and recorded to the Station Data Repository for
analysis by Protection and Control Engineers. COMTRADE files
and other data from multiple substations can be used to
perform forensic analysis (SOE) of large scale power disturbance
events (e.g. blackouts) to determine the root cause of the
disturbance, help improve system protection and guide future
mitigation strategies.

<span class="large"><b> Breaker Diagnostics</b></span>
<div class="col-xs-12">
<p>
By collecting the oscillography, phasor, voltage and amperage
data for each fault, GEM is able to analyze operating time
versus the power dissipated for the breaker, a parameter that
relates directly to the useful life of the breaker. This metric is of
great value to asset management systems as they move from
remedial to preventative maintenance strategies.

<span class="large"><b> GIS Mapping</b></span>
<div class="col-xs-12">
<p>
GEM’s Mapping module links GPS coordinates for grid
substations and devices assets with Google Earth and distanceto-
fault parameters to aid in tracing the source and geospatial
location of a fault or fault cluster.

<div class="col-xs-12">
<p>
GEM’s Weather Map module merges weather service layers for
rain, hail, surface winds and lightning strikes with the GIS Map
for grid assets to assist engineers with correlation with faults
and disturbances. Direction and speed of travel metrics aid in
the positioning of repair crews.

<span class="large"><b> Relay Settings</b></span>
<div class="col-xs-12">
<p>
In 2015, a NERC study determined that 31% of substation faults
were caused by relay settings not matching their design specs,
and Utilities were mandated to conduct periodic audits and
improve recordkeeping, a largely manual and error-prone
process. GEM’s Relay Settings module supports automatic,
periodic collection of relay settings from IEDs across the grid,
comparison to their design baseline, and notification of
Engineers via email and/or SMS when differences are detected.

<span class="large"><b> Firmware Revisions</b></span>
<div class="col-xs-12">
<p>
The same NERC study cited above also determined that out-ofdate
firmware also contributed to substation faults, and this
also led to Utilities adding that to their recordkeeping regime.
GEM supports automatic, periodic collection of firmware
revisions from IEDs across the grid, comparison to their design
baseline, and notification of Engineers via email and/or SMS
when differences are detected.

<div class="col-xs-12">
<p>
GEM’s Notifications module provides email and/or SMS alerts
and notifications for faults, events, and exception reports for
relay settings and firmware revisions. Notifications can also
trigger workflows processes, such as event report generation.

GEM offers a number of document templates that can be
automatically merged with fault & event data to produce a
formatted report to fulfill NERC reporting requirements.
Reports are emailed to Protection Engineering for review,
augmentation, and forwarding in PDF format.

<span class="large"><b> Secure Substation Access</b></span>
<div class="col-xs-12">
<p>
GEM’s Secure Substation Access module utilizes secure
tunneling protocol to establish a secure connection with a
remote substation. Users authenticate with GEM via Active
Directory or LDAP with their normal account and password,
followed by role-based authentication. All network traffic is
encrypted. Logging is performed using time-stamping and is
available to Administrator for NERC-CIP reporting. Once a
secure connection is established, IEDs may be accessed using
their proprietary console HMI or via GEM’s Station View
(described below).

<img src="img/IconStationView.png" alt="Station View" />
<span class="large"><b> Station View</b></span>
<div class="col-xs-12">
<p>
Most IEDs have a console HMI which uses a proprietary
protocol to support installation, setup, firmware updates and
diagnostic activities on the device. In most cases, these
activities can only be performed by personnel who are onsite
with the device. GEM’s Station View allows authorized
personnel to access the device remotely to execute console
functions, saving the time and travel expense to send personnel
to the site.
