Huawei AMI Solution
Consumers are more and more aware of the necessity to save energy in their home and to get a consumer cost effective monthly bill. In the next step they are adopting not only being consumers but also producers of energy, which would require an additional infrastructure. Conventional manual metering approaches face some critical challenges brought by the surge in p ower consumption and the expanding business scope of power companies. Such as:
Forward
•
Cannot acquire and analyze real-time power consumption which is necessary for effective line loss analysis.
•
Low efficiency and errors and low accuracy are inevitable in manual meter reading.
•
Cannot achieve pre-payment at multiple rates, remote control, or anti-power-stealing etc.
The key is to deploy Advanced Metering Infrastructure (AMI) in the power grids. AMI's upfront benefit is its ability to facilitate a favorable interaction between power companies and customers. To illustrate, it allows power companies to keep precise tabs on power consumption and lets consumers take actions to optimize their power use.
