A Smart Meter System that Improves
Smart Grid Performance
Enhanced Operating Efficiency
Wireless Mesh Network (WMN)
Complex control is required to control all the nodes for a Smart Meter System. Huge signal traffic from the hundreds of smart meters requires constant processing, slowing operations and requiring a large memory capacity.
Mitsubishi Electric offers below system:
- (1)
- Scheduling collection of AMR data from each meter. Data collection capacity has been enlarged by using concentrator initiative control instead of meter initiative access control.
- (2)
- Reducing the volume of mesh control signaling traffic.
- (3)
- Using low volume relay to speed operations and reduce required memory capacity.
Advanced Security Performance
Mitsubishi Electric has developed a state-of-the-art cryptographic algorithm which has been adopted as a global standard for protecting information used by electric power companies. The code is maintained by self-update processing for long-term, maintenance-free operation.
For secure, high-speed, energy saving communication
Advanced Single Phase Electric Meter
Product Features:
- Sleek, next-generation unit design
- Advanced functionality
- Selectable communications options
- Energy-saving
- Mitsubishi Electric quality
Early Detection of Tampering
Early detection is enabled by remote monitoring of the state of the meter at optional interval.
On-line Prepayment Assures Payment Collection
On-line prepayment capability assures payment for electricity usage. Remote monitoring of electricity usage also enables timely detection and response to malfunctions.
When a credit balance becomes low, the service center can notify the customer by email or SMS. Customers who do not pay can be dealt with remotely by activating a centralized disconnection switch.
Remote AMR Prevents Human Error and Improves Operating Efficiency
Malfunction Detection and Troubleshooting
Stable Electricity Supply through Demand Calculation and Load Peak Control
