Problems solved by technology

Using this software to simulate power grid faults and calculate the cumulative effect, it is necessary to perform power flow calculations according to the operating mode of the system, and manually specify the power flow files based on the stability files. The output stability results files need to manually extract the required transformer equipment in the fault The current value of the time period and manual calculation, need to use several software at the same time and may lead to certain human errors, reducing efficiency

Embodiment Construction

[0036] The present invention will be further described below in conjunction with the accompanying drawings. The following examples are only used to illustrate the technical solution of the present invention more clearly, but not to limit the protection scope of the present invention.

[0037] Such as figure 1 As shown, the batch transformer fault cumulative effect assessment method based on PSD-BPA includes the following steps:

[0038] Step 1, define that the fault set contains n+1 fault information, wherein the first n is historical fault information, and the n+1th is current fault information.

[0039] Step 2, define i=1.

[0040] Step 3, judge whether i is equal to n+1; if not, go to step 5, if yes, go to step 4.

[0041] Step 4: Analyze the i-th fault information through the fault analysis module in PSD-BPA, and judge whether the fault current information can be extracted, that is, whether there is corresponding fault recording data; if not, go to step 5; if yes, Acco...

Abstract

The present invention discloses a fault cumulative effect assessment method for PSD-BPA-based batch processing transformer and proposes the concept of fault cumulative effects. After the power system has the fault of short-circuit, calculating the cumulative effect on the equipment according to the obtained fault information and finally showing in graphical form so as to improved efficiency of using fault data; A cumulative effect value obtained from calculation can be ordered based on historical fault current transformer effect to provide transformer condition warning and equipment maintenance priority strategy so as to improve the stable working condition of network equipment and function as reference data of scheduling maintenance personnel making maintenance plan, thereby making maintenance plan become more directional and targeted so as to improve the processing speed and accuracy of information, reduce the manual costs and largely avoid human mistakes and errors.

Description

technical field [0001] The invention relates to a PSD-BPA-based batch processing transformer fault cumulative effect evaluation method, which belongs to the technical field of electric power automation. Background technique [0002] When a short-circuit fault occurs in the power grid, the penetrating short-circuit current flowing through the power grid equipment will have a certain impact on the equipment, and the cumulative effect of long-term multiple times will have a greater impact on the equipment. However, there is no effective quantitative evaluation method for the cumulative effect of short-circuit current. In addition, current research mainly focuses on the analysis of the impact of short-circuit current on directly faulted equipment, and rarely considers the cumulative effect of through-circuit short-circuit current on other related equipment in the entire network. effect impact. [0003] The evaluation of the cumulative effect of transformer faults in power syste...
