Power control method for standby power supply mode of electric equipment and electric equipment

[0054] refer to figure 1 , a power control method for standby power supply mode of electric equipment, comprising the following steps:

[0055] Step 1, obtain the voltage value V of the power output at any time i ; In this embodiment, the electrical equipment can obtain the voltage value V of the power output once every T time interval i; The power supply is commercial power, or generator, or UPS and inverter;

[0056] Step 2, the voltage value V at this moment i Compared with at least one set of preset voltage limits; wherein, each set of voltage limits includes a high voltage limit higher than normal voltage and a low voltage limit lower than normal voltage; judging the voltage value V i Whether it exceeds the range defined by the voltage limit, if not, return to step 1, if exceeded, enter step 3;

[0057] Step 3, reducing the required power of the electrical equipment according to the set adjustment range or adjustment speed.

[0058] After the required power of the elect

[0065] On the basis of Embodiment 1, set according to the expected configuration of the electrical equipment and the expected use environment; set the number of groups of required voltage limit values, and this embodiment includes at least 2 groups of voltage limit values;

[0066] There is an adjustment range or adjustment speed corresponding to each group of voltage limit values;

[0067] In step 2, judge the voltage value V i Whether it is beyond the range defined by the voltage limit is to judge the voltage value V i Is it satisfied:

[0068] exceeds any one or more of the high voltage limits in absolute value, or

[0069] Absolute value below any one or more of the low voltage limits;

[0070] If not satisfied, the voltage value V i Does not exceed the limit range; if satisfied, the voltage value V i beyond the limits;

[0071] In step 2, the voltage value V i Multiple voltage limits may be exceeded at the same time. Therefore, in step 3, reduce the power demand of th

[0081] In this embodiment, on the basis of the second embodiment, setting two sets of voltage limit values ​​is taken as an example for illustration.

[0082] refer to Figure 4 , in this embodiment, the high voltage limit of the first high limit curve H1 is V 1_H , the high voltage limit of the second high limit curve H2 is V 2_H ;The low voltage limit of the first low limit curve L1 is V 1_L , the low voltage limit of the second low limit curve L2 is V 2_L ;

[0083] In step 2, judge the voltage value V at any time i Whether it exceeds the range defined by the voltage limit includes:

[0084] If the moment V 1_L ≤V i ≤V 1_H , then the required power of the electrical equipment will not be adjusted;

[0085] If the moment V 2_L ≤V i 1_L or V 1_H i ≤V 2_H , then control the electrical equipment to reduce the required power of the electrical equipment at the set first adjustment speed or first adjustment range;

[0086] If the moment V i 2_L or V i >V 2_H , the el
