Energy and operational efficiency are most important concerns in any environments. Especially industrial customers need to measure their energy consumption to reduce their operating costs and enhance energy conservation in electrical infrastructure.
Energy management is a continual improvement process involving visualizing real-time data accuracy, measurement, analysis and implementation of event monitoring programs.
Industrial facilities are using to demonstrate the importance of managing the energy consumption. To addressing this issue, an energy monitoring and management devices are developed.
Monitoring devices are one of the important equipment that are using to measure the actual operating parameters of energy values and network characteristics to determine if energy efficiency can be improved and generate important information which analyzes the process of electrical energy transmission and distribution.
What is an electrical measuring device?
The measurement of electrical quantities is an essential part of almost any energy measuring plan. It can be realized as a measurement...
Saving energy is an extremely efficient way conserve resources. Whenever there is a room in the facility that is not in use, turn off the lights. There are many methodical ways to conserve energy, but installing solar panels is one of the most useful ways, especially for a big corporation. Solar panels convert the radiation of the sun's rays into usable energy and are 100% eco friendly. They help diminish pollution immensely and will help assure a better future for humans, animals, and nature.
More recent technological advancements in microprocessor relays, combined with GPS receivers for synchronization and accurate time stamping, is providing users advanced relay systems with synchronized measurements, called synchrophasor measurements Synchronized .Wide Area measurements (WAMs) is a relatively modern practice universal in the operation and control of electric power transmission. It consists of making synchronized measurements of phasor quantities of voltages and currents at several points spaced hundreds or thousands of kilometers points. Phasor Measurement Unit (PMU) technology provides phasor information (both magnitude and phase angle) in real time. The importance of data provided by PMUs has been well recognized after a number of major blackouts in many power systems in different parts of the world. PMU is an important component of WAMs.
Also, it requires a fast and secure communication to monitor real-time connection status to act as Energy Manager. [SANCHEZ]

Besides the calculation of electrical characteristics of the power system, power flow analysis can also help to optimize the system operating conditions and minimize the power losses [19].
Second is the cost allocation where energy is used to provide process or space heating, it is fundamental to know where the costs associated with energy are actually being incurred. The cost of energy are allocated to a particular product, department or other user by flowmetering which usually result in a significant reduction in total energy costs.
Given the extensive use of technology in today’s world, the energy consumed by computers and other electronic devices is a concern. It is estimated that the IT industry is responsible for over two percent of the carbon dioxide emissions released globally; this is approximately equal to that of the airline industry (“Dell aims to prove,” 2008). Manufacturers such as Dell make powerful computer processors whose energy use far outpaces the improved usefulness of the processor (“Dell aims to prove,” 2008). In addition, consumers usually leave their PCs running and companies leave their servers running nearly all the time, wasting a great deal of ...
In the present age, energy is the crucial and important factor for survival, but due to the depleting fossil fuels and soaring prices driven with globally unstable economic conditions, meeting the energy demand for the present day has become difficult and challenging. Refrigeration & Air conditioning (air cooling) which is a part in the day to day basis consumes about 50% of the total energy consumed by the buildings sector which accounts for about 30-40%. In hot temperature climate zones like east America, UK air conditioning/cooling equipment are predominant, in developing countries like China and India, the use of air conditioning for cooling purposes are increasing at a drastic rate.
For the prevantion of the electricity blackout we need to build smart power grid. A modernized electrical grid that uses analog or digital information and communications technology to gather and act on information, such as information about the behaviours of suppliers and consumers is known as a smart grid. This is used to improve the efficiency, reliability, economics, and sustainability of the production and distribution of electricity in an automated fashion[12]. The important aspects of smart grid is to electronic power conditioning and control of the production and distribution of
Where n is the number of tasks running at that time and Ui, j is the resource usage of task tj. The energy consumption Ei of a resource ri at any given time is defined as:
Electricity and electrical components are a major part of our lives today. Our lives pretty much come to a halt if there is a power outage or if our electrical devices stop working, sometimes we even start panicking because we are so dependent on these components that we cannot afford to lose them and their importance and use only increases as time passes. We all use these electrical devices and also electricity itself but most of us do not think about the math and physics that works behind all of these things.
The number of Electrical and electronic devices running on electricity are increasing at a rapid rate. At the same time the amount of electricity utilized by these devices is also increasing at high rate due to increased complexity in applications which are to be executed, thus overall electric utilization is increasing. Further wastage and over utilization became a concern making power efficiency of a device even more essential. Thus amount of power needed to run an application or execute a command becomes one of the main constraint of the device's efficiency. This is the area which is to be focused because of growing operational costs on servers. In this report we will discuss in brief about various techniques used for power management and our topic of interest along with their merits and demerits. We recommend some of the solutions for existing problems.
People are always looking for ways to save money. By using “Green” computer components you can save money and energy. Everyone having a computer powered on days at a time can use up a lot of energy, which will lead to a large energy bill. There is a lot of different ways to adapt your computer to be more energy efficient. Using more energy efficient computer components and changing settings in your operating system will save you big. By purchasing more energy efficient components such as processors, hard drives and computer monitors you can make your computer consume less power thus saving energy.
