The aim of this project is to create a program for load identification by means of the active and reactive power characteristics with the dataset called REDD. Specifically, it aims to evaluate the ability of the algorithm applied with respect to different types of appliances. In this semester, lots of technical papers had been studied and the useful know-how had been selected. The power calculation model in MS Excel had been verified, and the formulas to find out the results had been set up. To extract the data appropriately, the REDD dataset was also studied. Finally, the database of load signatures was built up for load recognition and this represents fifty percent of the project works has been completed. In next semester, an application program by LABVIEW or MATLAB will be created for completing the load identification task and the recognition performance will be evaluated.

INTRODUCTION In view of increasing power demand, escalating oil prices, exploding carbon credit market and the security concerns in nuclear power plant, it is time for us to rethink the way to deal with the energy needs. Although many new renewable energies have b... ... middle of paper ... ...es such as refrigerator, washing machine, smoke detector, etc.. That experience heightened the interest on researching the relevant technical papers and finding out the real situations. The problems encountered as seen in Chapter 6 described the difficulties of handling the large REDD dataset and extracting the required data from different data files. Through that challenging work, the skill to manipulate the large dataset and formulate appropriate calculations in MS Excel were practised. 9.3 Conclusion In conclusion, the tasks of this project has been fifty percent completed as explained in Chapter 9.1 and the remaining works in the coming semester for completing the project aims as seen in Chapter 7 are to create LABVIEW or MATLAB program for load identification and to evaluate the ability of the algorithm applied with respect to different types of appliances.
SCADA (supervisory control and data acquisition) is a graphical application used for monitoring and controlling systems in industry from a centralized location. It receives real time data from the PLC, and can be used to input values and turn on/off outputs. It can provide alarms to allow the user to know when a process has finished or if a fault has occurred. SCADA systems often use HMI (human-machine interface) to allow the user to control valves, pumps, etc. which the HMI is connected to (Inductive Automation, 2014).
The data and information I have collected is directly from the team of Australian Hardware team so this information is valid enough to be used for research of the given
My knowledge of engineering is reasonable and includes transformer substations, power plants, power distribution and transmission systems, industrial motor control and PLC programming, protective relay coordination, FACTS devices, grounding systems, Matlab programming and project management. In addition, I possess practical experience performing power flow, short-circuit and relay coordination analyses while using a power system modelling software such as ETAP, EDSA, DigSilent and CYME. Consequently, the aforementioned experience and solid engineering education along with your training will allow me to provide support to operating and new

In this section, the results of the research are presented. For each task carried out, the most important information obtained is presented.
A load is the force attributed to gravity and other sources of stress that are placed on a structure (Brannigan & Corbett, 2015). Loads can be placed in too many different categorized such as dead loads, live loads, impact loads, static and repeated loads, wind loads, and concentrated loads.
The first method of insuring a correct reading is obtained is through using one wattmeter on a balanced load. Using this on an unbalanced load will lead to an inaccurate reading for power. To complete this method a reading with a wattmeter connected from a single line to neutral via the voltage probes and in line with the line on the current probes. By multiplying the value of the wattmeter by three the total system power is found.
Automation is a step beyond mechanization, Automation is the use of control systems and information technologies to reduce the need for human work in production of goods and services. Where mechanization provided human operators with machinery to assist them with the muscular requirements of work, automation greatly decreases the need for human sensory and mental requirements as well. Automation plays an increasingly important role in the world economy and in daily life. Automatic systems are being preferred over manual system. Through this project we have tried to show automatic control of a house as a result of which power is saved to some extent. The Global System for Mobile Communications
Maximum Demand is the power consumed over a predetermined period of time, which is usually between 8– 30 minutes. The most common period of time, in the majority of countries, is 15 minutes.
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
Increased focus on energy conservation and demand prediction: Since prerequisite for any effective management is measurement, a high emphasis is observed on measuring and reporting of energy consumption at an increasingly granular level. Increased focus on the energy utilization is also due to the fact that the energy consumption level in the HVAC appliances is comparatively higher.
This paper presents vibration analysis model for automatic washing machine. This model can analyze vibrations in cabinet assembly of washing machine. General purpose motion analysis software ADAMS is used to create analysis model. Simulation results and experiment results are compared in various unbalanced conditions to validate this vibration analysis model. By using created model, various parameters are tested to reduce the vibration of cabinet assembly of washing machine.
