At this stage, during the construction of the smart grid, the actual installation and application of smart meters has also begun gradually, and the State Grid has also conducted multiple tenders for smart meters.
1. The development status of smart meters
"Full coverage, full collection, full cost control" is the goal of the construction of the electricity consumption information collection system. The full cost control function is the difficulty in the construction of the national power grid information collection system. With the continuous improvement of the level of power management, changes The old manual meter reading method is imminent in the past. The construction of a remote meter reading automation system to replace manual meter reading will fundamentally solve the phenomenon of inadequate meter reading, estimated reading, false reading, missed reading, etc. and meter reading data is not on time, out of time, and inaccurate. Shortcomings such as accuracy, slow statistical data, and long reporting period. At this stage, all provincial power companies are using technical means to refit smart meters on a large scale, realizing the user’s change from "using electricity first, then paying" to "paying first" The model change of "post-power consumption" strives to make residents' power consumption more intelligent and power supply services more humane.
Second, the application advantages of smart meters
The popularization and application of smart meters can promote the transformation of power supply companies from manual meter reading to automatic meter reading; at the same time, more detailed electricity consumption data can be obtained, and after analysis and processing, real-time electricity price information, payment information and electricity consumption information can be notified to users In this way, we can serve customers with better quality, and encourage users to use electricity more scientifically and reasonably, and actively participate in load regulation together. The specific performance is in the following aspects.
(1) Meter reading
After the implementation of smart meters, meter readers are no longer required to go to the site for collective reading, but to achieve full data collection. Meter readers basically realize transformation or transfer. Only smart meter maintenance personnel need to visit the site from time to time for inspection and verification, and abnormalities occur Check and correct afterwards. Due to the prepayment method, meter readers are reduced, and meter readers are trained as smart meter maintenance personnel; the accuracy of collected data is higher, and the level of power supply service is improved; electricity charges can be calculated on a daily basis, and the pre-collected electricity charges can be deducted daily , Is conducive to improving the recovery rate of electricity charges.
(2) Accounting
After the implementation of intelligent electricity meters, due to the high accuracy of data collection, there is no need for electricity bill accounting. Instead, a fixed meter reading settlement date is determined every month. The system automatically determines whether the electricity bill is abnormal, and automatically sends electricity bill information if there is no abnormality. If there is an abnormality, the abnormal process is initiated to the electricity billing center, and the electricity billing staff is responsible for judgment and processing. In the prepaid mode, the number of electricity bill accounting personnel is reduced, and the electricity bill accounting personnel are trained as data collection abnormal analysis and processing personnel; due to the high accuracy of data collection, the number of cases that need to be processed due to meter reading errors is also reduced.
