Embodiment 1
[0043] A method for measuring electricity with a super power factor, comprising the following steps:
[0044] (1) Preset the capacitive-inductive time interval, calibrated capacitive power factor PFset_Cap, calibrated inductive power factor PFset_Ind, calculation cycle, and timing mode; the value range of calibrated capacitive power factor PFset_Cap and calibrated inductive power factor PFset_Ind is [0,1], both are set to 0.92 in this embodiment, and the calculation period is set to 60 minutes. If the timing mode is half-point timing, such as 1:30 to 2:30, if the timing mode is hourly timing, such as 1 :00~2:00;
[0045] (2) Obtain the calibrated capacitive power factor PFset_Cap or the calibrated inductive power factor PFset_Ind involved in the calculation in each capacitive-inductive time interval in the current calculation cycle;
[0046] In this embodiment, each segment of the capacitive time interval in a current calculation cycle is as follows figure 1 As shown, since ...
Embodiment 2
[0065] In this embodiment, each segment of capacitative time interval in which a current calculation cycle is located is as follows figure 2 As shown, since the current calculation cycle is completely within the capacitive-inductive mixing time, that is, there is only a certain capacitive-inductive time interval in the current calculation cycle, it is necessary to judge whether the calibrated capacitive power factor PFset_Cap in step (2) is equal to the calibrated The inductive power factor PFset_Ind?
[0066] B1: If yes, then compare the actual capacitive power factor PF_cap with the actual inductive power factor PF_ind, the smaller value corresponds to the calibrated power factor and reactive energy increment, if PF_ind
[0067] B2: If not, compare the ratio PF_cap / PFset_Cap of the actual capacitive power factor with the ratio PF_ind / PFset_Ind of the actual inductive power factor, and take the calibrated power factor...
Embodiment 3
[0074] In this embodiment, each segment of capacitative time interval in which a current calculation cycle is located is as follows image 3 As shown, half of the current calculation cycle is in the capacitive-inductive mixing time, and the other half is in the capacitive time interval, that is, there are two capacitive-inductive time intervals in the current calculation cycle, then it is necessary to judge in step (2) Is the calibrated capacitive power factor PFset_Cap equal to the calibrated inductive power factor PFset_Ind?
[0075] If yes, then obtain the corresponding calibrated power factor according to B1 of Example 2 during the capacitive-inductive mixing time, and use the calibrated capacitive power factor PFset_Cap in the other half of the calculation cycle; if not, it will not be included this time calculate;
[0076] Assume that the calibrated inductive power factor PFset_Ind is obtained during the capacitive-inductive mixing time in step (2), and the calibrated c...
