The document discusses energy monitoring technologies and Crestron's energy monitoring and management solutions. It describes three main energy monitoring technologies: calculated/estimated, current monitoring, and power metering. Power metering is the most accurate but also the most expensive. The Crestron solution involves a six-part panel-based energy management system that uses current transformers, a current transformer interface, a meter control unit, a control processor, and analysis software to accurately monitor energy usage at the main panel and branch levels and integrate it into a building management system for energy management.

Smart Meter's are a part of Smart Grid,which display the consumption of electricity to end use customer as well as communicate to the utility side for demand side management.
The Advanced Distribution Management System – ADMS – brings together distribution management system (DMS), supervisory control and data acquisition (SCADA) and outage management system (OMS) technologies , along with control room applications, on one, secure platform with a single user interface. With this comprehensive mission critical solution, the electric utility can monitor, analyze and control the distribution network to improve the level and quality of service.
At its core is the network model representing the as-operated state and based on the as-built state defined by the geographic information system (GIS). A load flow algorithm responds quickly to data sourced from throughout the network to analyze the balanced, unbalanced and dynamically changing network in real time. Users across the network – operators, dispatchers, management, planning engineers and others – have consistent visualization of model results in geographic, schematic and single-line diagram views. State estimation validates viewed data and estimates non-telemetered points to achieve a complete network representation.
With this accurate network model and a portfolio of robust functionalities, the utility is empowered with continuous, real-time analysis of the operational state of the network that enables self-healing capabilities. Demand can be managed through reduction of technical losses; by forecasting near-term load and applying volt/VAR control for peak shaving; and by securely integrating and managing distributed energy resources, including energy storage, to flatten the daily load curve. These and other options enabled by ADMS are key to managing demand in the face of increasing energy usage, surging energy costs and network infrastructure instability due to aging.
The ADMS represents the evolution of control room technology that will help utilities mobilize to meet increasing consumer demand and environmental obligations and reap many of the benefits all stakeholders expect from their smart grid investments.
An electricity meter is a device for measuring the amount of
electrical energy used by consumers. Where electricity
companies install these meters at every subscriber, such as
homes, factories, administrative and government buildings and...,
after the electrical network is connected to their units to supply
loads such as lighting systems, fans, adaptations, office
appliances and any other equipment with electricity .
These meters may be mono or three-phase depending on the
nature of the contracted loads and electrical power. They may
also be connected directly to the electrical network or be
connected through auxiliary transformers ( current and / or
voltage transformers)

Building Management System-CPD - Part 1.pdfSilva104866
Why BAS ( BMS)…?
• Early days buildings were very simple with few facilities and services
• With time many services were introduced & crowded
• Now-a-days buildings are very complex with many services and higher
occupancy ( high consumptions of energy)
• Central Monitoring and controlling needed
Electrical Technology was founded on the remarkable discovery by Faraday that a changing magnetic flux creates an electric field. Out of that discovery, grew the largest and most complex engineering achievement of man : the electric power system. Indeed, life without electricity is now unimaginable. Electric power systems form the basic infrastructure of a country. Even as we read this, electrical energy is being produced at rates in excess of hundreds of giga-watts (1 GW = 1,000,000,000 W). Giant rotors spinning at speeds up to 3000 rotations per minute bring us the energy stored in the potential energy of water, or in fossil fuels. Yet we notice electricity only when the lights go out!
While the basic features of the electrical power system have remained practically unchanged in the past century, but there are some significant milestones in the evolution of electrical power systems.
SmartSense range of solutions assist Industrial and Commercial customers in reducing their energy inefficiencies through the use of Energy analytics and control

2. Market Direction
• The lighting control industry being driven to manage energy
holistically and to show ROI
– Energy costs are going to go up
– Changing regulations are impacting local building codes
– Clean energy is expensive and unreliable for the supply side
– Being green is not just a marketing strategy, it’s a necessity to be efficient
and reduce operating expenses
3. What do you need?
• Products that can actually help lower operating costs
• Products help owners and facility managers prove that they’re
doing the right thing
• Transition from simply monitoring energy usage to
management of energy
4. Energy Monitoring
• Hardware and software that connects to your energy
resources to provide a defined baseline of energy
consumption
• Knowing is the start – you need to see what your
energy usage is as a starting point
6. Calculated - Good
• If we know that a load is 50W and it’s at 50%, can’t we
just assume it’s using 25W?
– Not really…
– We can get fairly close with load profiling, but the wattage numbers
don’t scale linearly
– Commercially, ballasts are very difficult to accurately profile
– The numbers produced by these guesses can be off by 20%
• Really only works for lighting, not all loads
7. Current Monitoring - Better
• Assume that the voltage is stable and measure the actual
current
– P=I*V
– Can provide fairly accurate results for stable voltages
– Has a problem with active loads, like ballasts
• Power factor correction helps in the “on” state
• “Off” state will read much higher than actual power due to phase shifts
– Can expect a 10% error in measurements
• Can be used for non-lighting loads
8. Power Metering - Best
• Samples real voltage and real current at high frequencies
• Compensates for phase offsets
• Doesn’t get fooled by voltage drops or non-linear current
scaling
• Expensive
• Errors can be smaller than 1%
• Useful for measuring ANY electrical load
9. Crestron Solution
• Whatever your level of energy sustainability, we can help
make an impact
• We have calculated, current monitoring and power
metering solutions to help you grow and evolve your level
of energy management
10. Crestron Calculated Solutions

– Voltage
– Active Power
– Pulse Rate
• Historical Information – Energy
– Voltage
– Current
– Active Power
– Energy
– Pulse Usage
– Power Factor
– Energy Meter (aggregated)
– Pule Meter (aggregated)
19. Pulse Metering
• Allows for inclusion of 3rd party metering devices
• Keeps precise count of pulse rate and pulse count
• Typically used for water or natural gas
20. Odds and Ends
• Often, for larger buildings, the main feed is much
larger than 600A. How does this get monitored?
– For these large installations the feed is typically broken
up into multiple, parallel, 600A (or less) feeds
– Our tools allow us to clamp one CT onto one parallel
feed and instruct the monitor to compensate for the fact
that multiple feeds are in use (Basic multiplication)
21. Energy Monitoring Technologies - Recap
• Three monitoring technologies
– Guessed/Estimated
• Supported by all Crestron products
• Not as accurate
– Current Measurement Only
• Supported by Crestron PM option products
• Mid-level accuracy
– Power Measurement
• Measured by a dedicated device: GLS-EM-MCU
• Most accurate option for measurement
22. Bringing It All Together
• All of these work well independently
• The real power is harnessed when you bring these
technologies together into a overarching energy
management strategy
24. Making the Transition from Monitoring to Management
• Using the data gathered from the energy monitoring
hardware and software, the facility manager realizes
there’s an opportunity for savings
• Now that there are metrics, the goal is to make the
numbers move
– We do this via our control products and Fusion™
25. What are the steps involved?
• Metering your energy consumption and collecting the data by using an
energy monitoring software
• Uncover places to save energy - such as making upgrades or replacing
inefficient equipment
• Putting into place energy saving functions – such as demand response
settings or eliminating wasted energy in unoccupied spaces
• Tracking progress by analyzing the real-time data and comparing with
historical information to what these efforts are actually achieving
