Implementation of Power Line Communication for energy measurement
Power line communication (PLC), also known as power line carrier, is a system for transmitting information on an electrical conductor used for carrying electric power from high voltage transmission lines, distribution lines, and to lower voltage lines used inside buildings. All PLC systems operate by applying a modulated carrier signal on the existing electrical wiring system. There are different types of power line communications, depending on frequency bands used. The aim of this work is to receive the monthly energy consumption from a remote location directly to a centralized office. In this way we can reduce human efforts needed to record the meter readings which are till now recorded by visiting every home individually.This can be achieved by the use of Microcontroller unit that continuously monitors and records the Energy Meter readings in its permanent (non-volatile) memory location. This system also makes use of a PLC modem for remote monitoring and control of Energy Meter.
A Low Cost Energy Meter Internet Interface
Internet communications facilities are present in almost all power substations. Unfortunately, automation devices aren't web enabled, being unable to transmit or receive IP data. This article presents a low/cost energy meter reading interface application suitable for using with old meters equipped with pulse generators. Energy pulses for every quarter of an hour are counted on a microcontroller and stored on a non-volatile memory, data required by the application being transmitted to the energy dispatcher control unit via an Internet communication embedded microcontroller. We used a very low cost microcontroller to interface the existing meters and the energy balance software application. Using standard Ethernet network communications is also a new idea in this field, all data will be available in real time to the energy management unit. The application presented in this paper does not interfere with the billing data from the meter memory, so there is no need for metrology test...
Renewable Energy and Power Quality Journal
This paper discusses the development and implementation of a digital power quality meter to comply with the new standard which will regulate the Power Quality in Brazil. Its main objective has been to become a low cost device capable of monitoring the main Power Quality indices of the new standard, such as the steady state RMS voltage, harmonic distortion, voltage fluctuation, voltage unbalance, voltage sags and swells, as well as power supply interruptions in real-time. Through a cellular GPRS module, the meter can be remotely controlled and configured. In this way, it can exchange measurements and information data with a remote server, thus constituting a Power Quality monitoring system.

Advanced Electricity Usage via Power Line Communications
Power line communication (PLC) presents an interesting and economical solution for Automatic Meter Reading (AMR). If an AMR system via PLC is set in a power delivery system, a detection system for illegal electricity usage may be easily added in the existing PLC network. In the detection system, the second digitally energy meter chip is used and the value of energy is stored. The recorded energy is compared with the value at the main kilo Watt-hour meter. In the case of the difference between two recorded energy data, an error signal is generated and transmitted via PLC network. The detector and control system is proposed. The architecture of the system and their critical components are given. The measurement results are given.

This paper presents a microdevice for monitoring, control and management of electric loads at home. The key idea is to compact the electronic design as much as possible in order to install it inside a Schuko socket. Moreover, the electronic Schuko socket (electronic microdevice + Schuko socket) has the feature of communicating with a central unit and with other microdevices over the existing powerlines. Using the existing power lines, the proposed device can be installed in new buildings or in old ones. The main use of this device is to monitor, control and manage electric loads to save energy and prevent accidents produced by different kind of devices (e.g., iron) used in domestic tasks. The developed smart device is based on a single phase multifunction energy meter manufactured by Analog Devices (ADE7753) to measure the consumption of electrical energy and then to transmit it using a serial interface. To provide current measurement information to the ADE7753, an ultra flat SMD open loop integrated circuit current transducer based on the Hall effect principle manufactured by Lem (FHS-40P/SP600) has been used. Moreover, each smart device has a PL-3120 smart transceiver manufactured by LonWorks to execute the user's program, to communicate with the ADE7753 via serial interface and to transmit information to the central unit via powerline communication. Experimental results show the exactitude of the measurements made using the developed smart device.
Energy Management by High Speed Remote Monitoring of Energy Meters
— How Can We Manage What We Do Not Measure? The primary working of high speed remote monitoring of energy meters includes fetching of data from energy meters i.e. voltages, currents, power, power factor etc. and send that data to controller or server. The interface between server & meters will be based on MODBUS RTU protocol over TCP/IP via Ethernet. Reducing energy consumption as well as waste is now widely seen as being good for economy, as well as good for environment. However, the top management of organization typically does not have the information about their energy consumptions, so they make informed to take proactive decisions about their facility's energy use. Energy initiatives too often are one time improvements if that are not monitored & measured properly over time the benefits of these improvements are soon lost to avoid this we have to observe the energy consumption continuously. Energy Remote Monitoring is a perfect solution that delivers a visible impact to the base line. Using Web-based technology, Communication protocols & GS M technology, energy remote monitoring delivers real time information, analysis, and guidance that allow executives to understand their energy use, take appropriate action, and continually improve energy efficiency and performance.

In this study, a nationwide real-time monitoring system has been developed to monitor all electrical quantities and power quality (PQ) parameters of the electricity transmission network including its interfaces with the generation and distribution systems. The implemented system is constituted of extended PQ analysers (PQ + analysers), a national monitoring center for power quality (NMCPQ), and the PQ retrieval and analysis software suite. The PQ + analyser is specifically designed for multipurpose usage such as event recording and raw data collection, in addition to the usual PQ analysis functions. The system has been designed to support up to 1000 PQ + analysers, to make the electricity transmission system and its interfaces completely observable in the future. The remote monitoring, analysis and reporting interface, the map-based interface, and the real-time monitoring interface, as well as the Web applications run on the NMCPQ servers, can be accessed by the utility, large industrial plants, distribution companies and researchers, to the extent of the authorisation given by the transmission system operator. By activating sufficient number of analogue and digital outputs of PQ + analysers, and equipping the NMCPQ with necessary hardware, analysis and decision making software, the proposed system can serve as an advanced supervisory control and data acquisition system in the future. The proposed monitoring concept can be extended to serve the needs of the modern electricity markets, by making various regulations, codes and instructions implementable.
