Smart Meters

  1. 1. Presented By:- Anshul Shrivastava (Power Distribution with Specialized in Smart Grid) UNIVERSITY OF PETROLEUM & ENERGY STUDIES,DEHRADUN,India Smart Meter
  2. 2. What is the electric grid?  The electric grid is the path over which electricity flows from power generating facilities across high-voltage, high volume transmission lines to local communities  The grid interconnects generators, power transmission systems, local distribution utilities and end users of electricity  The system is designed and operated for safe, reliable electric reliability under constantly changing load conditions.
  3. 3. What makes it a smart grid?  Smart grid is an umbrella term for the modernization of electric transmission and distribution.  It is an integration of a more modern electric grid with communications and information systems to better monitor and control the flow and consumption of energy.  Save energy  Reduced Cost  Increase Reliability
  4. 4. What are smart meters and its benefits?  A “smart” or advanced meter is an electric meter that acts as a gateway for two-way communications or information exchange between the consumer and the utility  Measure Energy Usage with Greater Detail  Provide Consume energy data to utility in Real time via home display and web based Program.  Remote Function  Detect Meter Tampering and offer new pricing programs to encourage peak load reduction.  It can be more motivated to take advantage of incentives to reduce consumption, especially during peak demand periods, and save money.
  5. 5. How are smart meters different than current meters?  From Conventional Meter’s which can provide usage data to the company’s information systems for monthly billing.  Smart meter can provide “last gasp” notification of outages and detect possible theft. The newer, advanced meters are considered “bi-directional” or two-way and can be linked to the utility’s communications network and smart grid, as well as a consumer’s home area network, programmable thermostat, and smart appliances.
  6. 6. Benefits of Smart Meter/Smart Grid  Improved power quality,  More efficient  Secure power delivery  Enhanced electric reliability  Prepayment Options Available  Load survey / profiling helping in demand forecasting  Over-the-air firmware and configuration upgrade  More accurate bills — smart meters mean the end of estimated bills, and the end of overpaying (or underpaying) for your energy  Automatic Meter Reading Through ZIGBEE/HAN/LAN Network.  Better oversight and management of your energy use with a real-time data display in your home

  10. 10. GMS / GPRS enabled smart meter modules  GSM based meter data collection modules available for industrial and transformer metering  Integrates with various type of meters using serial port  Built-in remote firmware upgrade(over-the-air upgrade) and remote diagnostics
  11. 11. GPRS / Ethernet based data concentrators / gateways for meter data collection  Can collect data from up to 500 electricity smart meters in a PAN (network)  Can collect data as fast as every 30 minutes  Local storage for offline mode in case of loss of connectivity  Connects to the web server via GPRS or Ethernet (LAN connection)  Built-in remote firmware upgrade(over-the-air upgrade) and remote diagnostics  Maintains diagnostics and connectivity information of the whole PAN (network)  Environment proof with optional IP-65 / 67 enclosures  Tamper proof with instant SMS to service engineers  Built-in battery to transmit data in case of loss of power
  12. 12. Cloud enabled MDM software  Maven's cloud enabled software provides a scalable, secure and highly reliable software for smart meter data collection and management  Collects data from data concentrator units / gateways and maintains the consumer / meter information  Hosted on the Google cloud (or equivalent) for 99% uptime  Continuous availability of latest data at desired polling frequency  Can connect to thousands of DCUs for data collection  Various alerts as per need over SMS and e-mail  128-bit SSL encryption for data security  Analytical capabilities with graphical data visualizations help in decision making
  13. 13. Repeaters  Used for remote / sparsely populated locations  Can be installed on electricity poles / street lights  Used to carry data from local networks to far away locations
