Energy management system
What is Energy Management Systems?
- Framework for managing the energy usage systematically and efficiently
- It can be referred to a system which is designed specifically for the monitoring, Analysis , Control of network Load and distribution components like motor loads, machinery loads, Lighting Loads , Office loads of large commercial buildings or Industrial plants.
- It is defined as the system to manage the working and the performance of the energy use such as energy efficiency, specific energy consumption, energy saving tips and different kind of such processes leading to energy savings are known as energy management system (EMS).
The Energy Management System or EMS as we know it today had its origin in the need for electric
utility companies to operate their generators as economically as possible. That there was ample
cost justification for this has been demonstrated many times. At this point, I shall refer to an
electric power system as consisting of generators, transmission system, and the distribution system
to customer loads.
To operate the system as economically as possible required that the characteristics of all
generating units be available in one location so that the most efficient units could be dispatched
properly along with the less efficient. In addition, there was a requirement that the on/off
scheduling of generating units be done in an efficient manner as well.
Finally, the scheduling of generators with limited fuel or water supplies were incorporated in
energy management systems. This allows operators to further reduce the cost of operation by taking
advantage of cheaper fuels or hydro power.
When operating within a vertically integrated electric utility - i.e., one which owns and operates
the generation, transmission, and the distribution the economic dispatch and scheduling of
generation is usually done to minimize the total operating cost of generation. When the electric
system is unbundled, the economic dispatch and scheduling is done on the basis of prices bid to a
central office.
Energy Management System (EMS) is a collection of computerized tools used to monitor,
control, and optimize the performance of generation and transmission systems. This intelligent
energy management software control system is designed to reduce energy consumption, improve
the utilization of the system, increase reliability, and predict electrical system performance as
well as optimize energy usage to reduce cost. Energy Management System applications use realtime
data such as frequency, actual generation, tie-line load flows, and plant units’ controller
status to provide system changes. Energy Management System had its origin in the need for
electric utility companies to operate their generators as economically as possible. To operate the
system as economically as possible required that the characteristics of all generating units be
available in one location so that the most efficient units could be dispatched properly along with
the less efficient. In addition, there was a requirement that the on/off scheduling of generating
units be done in an efficient manner as well. Energy management systems can also provide
metering, sub metering, and monitoring functions that allow facility and building managers to
gather data and insight that allows them to make more informed decisions about energy activities
across their sites.
Why should one go for EMS?
Benefits of NECPL EMS:
- Reductions in energy cost and other related environmental impacts, through systematic management of energy.
- It also provides facilities for monitoring and recording of electricity, gas, water or other fuels or energy source consumption through special meters.
- The data obtained from these can then be used to produce trend analysis for daily , weekly , monthly and annual energy consumption forecasts against other parameters like production and services etc.
- Remote access to the crucial data for energy consumption in different locations & allows to compare energy usage by equipment type, store location, fuel type or time of day and provides potentials for energy savings.NECPL offer innovative EMS
- Installation and Implementation of Energy monitoring meters and Analyzers with Web based energy management software-POWERBUS
- We also provide consultancy to organizations to make their documentation and training to employees for Energy management system leading to IS 50001 like EMS program, EMS implementation program, internal auditors program and make the team competent leading the organization to certification.
- Provide training on energy management system to senior, middle & junior management in the organization for awareness, implementation, and internal auditors program for competence building. http://www.powerqualityindia.com/ea5.html
EMS in Power Systems
Electrical energy management systems (EMS) are an important function for the reliable and
efficient operation of power systems. EMS is related to the real time monitoring, operation and
control of a power system. The information from the power system is read through Remote
Terminal Units (RTUs), an integral part of SCADA to an EMS or Energy Control Centre (ECC).
EMS consists of both hardware and software. Hardware part of EMS consists of RTU, Intelligent
Electronic Device (IED), Protection, Computer networking, .etc. Software part of EMS consists
of Application programs for network analysis of power systems. In EMS, application programs
are run in a real time as well as extended real time environment to keep the power system in a
secure operating state. Now-days, EMS is an integral part of any power system. It is used as a
part of Substation Automation System (SAS), Demand Side Management (DSM), Protection,
and Distribution Management Systems (DMS) for renewable energy and so-on. In the next few
years, EMS-DMA will change the role of power systems, monitoring and control.
An energy management system (EMS) is a system of computer-aided tools used by operators of
electric utility grids to monitor, control, and optimize the performance of the generation and/or
transmission system. The monitor and control functions are known as Supervisory Control and
Data Acquisition (SCADA), followed by several on-line application functions. Energy
Management Software (EMS) is a general term referring to a variety of energy-related software
applications which may provide utility bill tracking, real-time metering and lighting control
systems, building simulation and modeling, carbon and sustainability reporting , demand
response, and/or energy audits. Managing energy can require a system of systems approach.
- Facilitate the management of energy usage in the building or industrial facilities for bench marking against specific parameters of production , services, area or manpower etc
- Trending and monitoring energy consumption with other parameters at multiple locations , on mobile or tablet PCs.
- Automatic and consistent reaction to events and alarms , thus lowering or avoiding the downtime.
- Provide a means together and view information quickly to take decisions
