1. About the “Centralized remote meter data collection technology”
AMR or Automatic Meter Reading system has been implemented globally for years to replace manual data collection because it addresses certain drawbacks of manual work, including High labor cost, non-simultaneous collection of data, and human errors. Each meter in AMR is attached to a data transmitter, which sends data to the centralized system.
2. Implementation at EVNHCMC
Ho Chi Minh City Power Corporation has piloted several international advanced remote data collection technologies since the promulgation of the Smart grid development roadmap approved by the Prime Minister in 2012, such as: Power-line communication (PLC), Radio Frequency Mesh (RF-MESH) and direct meter data collection via GPRS/3G modems.
Customers who have used electronic meters and connected to the remote data collection system have all given positive feedback regarding the features and efficiency of the system. The results indicate high efficiency and economic impacts for the customers as they are now able to track and monitor their electricity usage. In addition, AMR enables the Electricity operators to update the power supply of each customer, which informs the development of effective solutions to minimize outage time and further improve electricity supply quality.
3. Benefits from the installation of electric meters and the centralized remote meter data collection system
The benefits highlight greater convenience for the customers and higher electricity service quality, specifically:
Greater convenience for the customers:
- Periodic meter data is now collected remotely and sent to the customers via SMS, reducing the hassle of manual recording.
- Reduced outage time, quick response to failures thanks to early detection of incidents based on data analysis and timely settlement of potential causes of damage to electrical equipment and grid.
- Real-time tracking and monitoring of electricity usage, enabling customers to adjust their usage for the highest efficiency and economics.
- Improving electricity quality, minimizing equipment damage due to electricity quality.
Electricity operators:
- Closely monitoring electricity supply, early detection and settlement of abnormalities, thus improving the service quality.
- Proactive management and forecast of customer demand for appropriate investment, maintenance and upgrade plans; development of solutions to minimize outage time.
Increasing production and business productivity and efficiency.
