[0105] S210: Obtain first pulse constant information according to the first active power relationship equation and the first reactive power relationship equation and in accordance with inherent rules of active power and reactive power.

[0106] It should be noted that the first time information is the time during which the first power signal is at the first level within the preset pulse time threshold; the second time information is the time during which the second power signal is at the first level within the preset pulse time threshold. The preset measurement formula is:

[0107] T1 = k / C*P;

[0108] T2 = k / C*Q;

[0109] In the formula:

[0110] T1 is the time when the pulse signal of active power is at the first level, which corresponds to the first time information in this embodiment;

[0111] T2 is the time during which the reactive power pulse signal is at the first level, which corresponds to the second time information in this embodiment;

[0112] k is the fixed calculation coefficient set by the metering device;

[0113] C is a pulse constant, which corresponds to the first pulse constant information in this embodiment;

[0114] P is the active power of the electrical power;

[0115] Q is the reactive power of the electrical power.

[0116] The above formulas can be used to obtain the relationship between the first pulse constant information and the active power of electricity, namely the first active relationship, and the relationship between the first pulse constant information and the reactive power of electricity, namely the first reactive relationship.
