Abstract

The invention provides a payment method for an electric energy meter, which includes the following main steps: S2, judging whether to select a conventional prepayment mode, if selected, then enters S3, if not selected, then enters S7; S3, judges whether it is positive electricity, If yes, go to S5; S4, judge whether it is negative power; if so, go to S5; S5, deduct the recharge balance; S7, judge whether to choose the priority deduction mode, if so, go to S8; S8, judge whether it is positive If so, go to S9; S9, judge whether the negative power is sufficient, if so, go to S10; S10, deduct the negative power, go to S11; S14, judge whether it is negative power; if so, go to S15; S15, accumulating the negative electric quantity, and proceeding to S16. In the present invention, there is a priority deduction mode. When positive electricity is used, negative electricity will be deducted preferentially. The user's contribution to grid charging can be reasonably rewarded, making the management of electricity more reasonable.

Description

technical field

[0001] The invention relates to the technical field of electric energy meters, in particular to a payment method for electric energy meters. Background technique

[0002] like figure 1 As shown, the payment method of the existing household electric energy meter generally adopts the management of electricity consumption before payment or prepayment. There is only positive energy management and no negative energy management. Users of self-generated solar energy, when their power is surplus, will reversely charge the grid to generate negative power, and this part of negative power will be used by other users normally from the grid, and other users will also pay normally, but the current charge to the grid During reverse charging, the energy meter will not make statistics on this part of the negative power, and the power company will not make statistics on this part of the negative power, so the power company will get extra income, but the power contribution of ...
