Embodiment 1
[0034] Such as figure 1 As shown, it is a flow chart of a method for measuring and calculating the standby power of electrical equipment invented, and the specific steps are as follows:
[0035] (1) Collect the current power value of the electrical equipment at the set collection time interval
[0036] In this embodiment, the air conditioner will be used as a typical electrical equipment for related descriptions, such as figure 2 As shown in , it is a power change curve from power-on to start-up of an air conditioner.
[0037] The current power value of the air conditioner is collected by the power collection device at a set collection time interval. The collection time interval can be set artificially, for example, it can be 0.1s or 0.05s, but the smaller the interval, the more accurate the final calculated value. This implementation Example 1 takes 0.1s as an example.
[0038] Select 10 consecutive collection points in the collection time axis as a collection window peri...
Embodiment 2
[0055] like image 3 As shown, it is a flow chart of another method for measuring and calculating the standby power of electrical equipment according to the present invention, which specifically includes the following steps:
[0056] (1) Collect the current power value of the electrical equipment with the set collection time interval, and continuously take n (n is a natural number greater than or equal to 3) window period values in the collection time axis. In this embodiment 2, n takes 3 ;
[0057] This embodiment 2, if Figure 4 Shown is the power change curve of an air conditioner from running to standby.
[0058] The current power value of the air conditioner is collected by the power collection device at a set collection interval. The collection time interval can be set artificially, such as 0.1s, 0.05s, but the smaller the interval, the more accurate the final calculated value. In this embodiment 2 Take 0.1s as an example.
[0059] Select 10 continuous collection p...

Abstract
The invention provides a method for measuring and calculating the standby power of electrical equipment, which belongs to the field of measurement and calculation. Collect the current power value of the electrical equipment by setting the acquisition time interval, set the acquisition window period, and judge the power jump when the power jump occurs, and obtain the accurate standby power by checking the power in the window period, and finally calculate the power consumption of the electrical equipment. Standby power. The invention can satisfy the measurement and calculation of standby power consumption of different types of electrical equipment, overcomes the problem that the electrical equipment cannot be accurately calculated due to low power factor under standby conditions, and can obtain a relatively accurate standby power value.
Description
technical field [0001] The invention relates to the field of measurement and calculation, in particular to a method for measuring and calculating the standby power of electrical equipment. Background technique [0002] With the development of the times, there are more and more types of electrical equipment in modern families, and the electricity consumption of residents is getting higher and higher. Many users do not have the habit of cutting off the power when they are not using electrical appliances, resulting in a large amount of standby electricity being wasted every year. Many people have begun to pay attention to whether there is hidden power consumption in household appliances, and there is an urgent need for the detection of standby power consumption of electrical equipment. General households are tested with a power tester, but the test is the current power, which cannot normally reflect the actual results. Contents of the invention [0003] Aiming at the deficie...
