Abstract
The invention discloses a time-of-use pricing electric energy measurement analyzer and an application method thereof, related to the technical field of measuring electrical variables. The time-of-usepricing electric energy measurement analyzer is provided with an information and communication output module, a signal processing module and an operation processing module, and is further provided with a period control circuit connected with a data processing unit, wherein the analyzer can be applied to a time-of-use pricing billing without meter. The time-of-use pricing electric energy measurement analyzer and the application method thereof, provided by the invention, have the following beneficial effects: the analyzer has a function of time-of-use pricing, and under the premise of performingdeep researching on actual power of a secondary circuit, a new electric energy further charging method is provided. With the analyzer and the method provided by the invention, changing an electric energy meter without cutting off power supply of a power supply line is allowed, moreover, total supplied power during a period when the electric energy meter is not provided can be accurately added up,further charging of power for the user is facilitated, doubt of the user can be dispelled, and excellent service level is improved.
Description
technical field [0001] The invention relates to the technical field of measuring electric variables, in particular to an electric energy metering analyzer for time-of-use pricing and an application method thereof. Background technique [0002] For faulty electric energy meters or super-period electric energy meters, it is necessary to bring new electric energy meters to replace the on-site electric energy meters. Since there is no meter billing during the meter replacement period, it is necessary to carry out power replenishment work after the meter replacement is completed. [0003] The traditional power recovery method is: record the voltage and current before and after meter replacement to calculate the average power during meter replacement, record the power factor before and after meter replacement to calculate the average power factor, record the time spent on meter replacement, use (power × power factor × meter change time × metering point magnification) method to obt...
