Embodiment Construction

[0018] In the following description, specific details such as specific system structures and technologies are presented for the purpose of illustration rather than limitation, so as to thoroughly understand the embodiments of the present invention. It will be apparent, however, to one skilled in the art that the invention may be practiced in other embodiments without these specific details. In other instances, detailed descriptions of well-known systems, devices, circuits, and methods are omitted so as not to obscure the description of the present invention with unnecessary detail.

[0019] In order to illustrate the technical solutions of the present invention, specific examples are used below to illustrate.

[0020] Such as figure 1 As shown, the logic flow chart of the method for determining the influencing factors of transformer fixed loss provided by the embodiment of the invention includes:

[0021] Collect the fixed loss of the transformer twice, and make the differen...

Abstract

The invention is applicable to the technical field of transformers and provides a transformer fixed loss influence factor determination method, which comprises the following steps: firstly, the fixedloss of a transformer is collected twice, and the twice collected fixed loss makes a difference to form a standard variation M; X influence factors of the transformer fixed loss are determined; then,the X influence factors are checked one by one; when the influence factors during twice collection are different, the fixed loss caused by difference of the influence factors is worked out; afterwards, the calculated fixed loss is subtracted from the standard variation M to obtain MY; when MY is equal to 0, checking of the influence factors is finished. Through such a manner can one or more influence factors influencing the transformer fixed loss be obtained; and the problem of large difficulty of determining the influence factor of the transformer fixed loss in the prior art is solved.

Description

technical field [0001] The invention belongs to the technical field of transformers, in particular to a method for determining influencing factors of fixed loss of transformers. Background technique [0002] The fixed loss of the transformer is an important part of the power loss of the transformer. Compared with the variable loss of the transformer or the loss of other components, the size of the fixed loss is relatively stable. From the calculation results of the theoretical line loss of the transmission network, the iron loss of the 220kV and 500kV power grid transformer is between The total loss of the transformer accounts for more than half, and the iron loss of the 110kV transformer accounts for 60% of the total loss of the transformer. On the one hand, the iron loss of the transformer accounts for a large proportion, which has a great impact on the total loss of the power grid, and higher requirements should be put forward for the accuracy of the statistics of the iro...
