Ice Cover Prediction for Transmission Lines Based on Feature Extraction and an Improved Transformer Scheme
Round 1
Reviewer 1 Report
Comments and Suggestions for AuthorsThe article describes an interesting and current topic, it is well structured, the relevant literature is analyzed in detail, the methodology is clearly explained, the results support the research and are quite well presented.
However, a few small things should be fixed.
- In the Abstract, the second and third sentences are almost the same. I suggest to delete the second sentence of the abstract.
- In line 30, the expression "dancing of transmission lines" is not adequate, swinging or sagging should have been?
- A Figure in the introduction is not appropriate, therefore Fig. 1 should be moved to the next section. Maybe not all photos are needed, four is enough, but they should be enlarged, to serve the purpose.
- A letter is missing at the beginning of the sentence in the 36th line.
- In Figure 5, the coordinate axes should be marked correctly, the measurement unit [°C], [%], [m/s] [mm ]or [cm] is missing, the samples on the x axis...
- In figures 6 - 10 there are very small letters, enlarge the pictures as much as possible and additionally enlarge the letters so that they are legible when printed on A4 paper.
- Finally, in the conclusion, the achievements of the scientific contributions mentioned in the introduction, the limitations and possible shortcomings of the proposed method, as well as recommendations for improvement in future work should be referred to.

Dear Reviewer,
We appreciate your effort in carefully reviewing our manuscript and your useful feedback. Based on your comments, we have thoroughly revised our manuscript. Our point-to-point responses to your comments are given below.
1. Response to comment: (In the Abstract, the second and third sentences are almost the same. I suggest to delete the second sentence of the abstract.)
Response: Thank you for your reminder and we are very sorry for our careless in our manuscript.
We have deleted the second sentence of the abstract and looked up, revised the incorrect formats throughout review this paper.
2. Response to comment: (In line 30, the expression "dancing of transmission lines" is not adequate, swinging or sagging should have been?)
Response: Thank you for your questions and we are very sorry for our inaccurate description on "dancing of transmission lines". As properly stated by the reviewer, it should be ‘swinging’ not ‘dancing’.
We have updated the manuscript by revising “dancing of transmission lines” to “swinging of transmission lines” at line 30.
3. Response to comment: (A Figure in the introduction is not appropriate, therefore Fig. 1 should be moved to the next section. Maybe not all photos are needed, four is enough, but they should be enlarged, to serve the purpose.)
Response: Thank you for your correct suggestions and we are sorry for our inappropriate representation on Figure 1.
We have updated the manuscript by moving Figure 1 to Section 2 on Page 5 and added the description on Figure1 at line 174 on Page 4.
4. Response to comment: (A letter is missing at the beginning of the sentence in the 36th line.)
Response: We are very sorry for our careless in our manuscript.
We have updated the manuscript by revising the “ecent” to “Recent” in line 37.
5. Response to comment: (In Figure 5, the coordinate axes should be marked correctly, the measurement unit [°C], [%], [m/s] [mm ]or [cm] is missing, the samples on the x axis...)
Response: Thank you for your correct suggestions and we are sorry for our inappropriate description on Figure 5.
We have revised the Figure5 and added the coordinate axes and measurement unit.
6. Response to comment: (In figures 6 - 10 there are very small letters, enlarge the pictures as much as possible and additionally enlarge the letters so that they are legible when printed on A4 paper.).
Response: Thanks for your suggestions and we are sorry for our unclear description on Figures 6-10. We have tried our best to adjust all font sizes (scale, text, etc.) in Figures 6-10, increasing the font size from 10.5 to 14. However, due to the large number of sub-image in Figures 6 and 7, increasing the font size will involve overlapping issues if the font size is over 14.
7. Response to comment: (Finally, in the conclusion, the achievements of the scientific contributions mentioned in the introduction, the limitations and possible shortcomings of the proposed method, as well as recommendations for improvement in future work should be referred to.)
Response: Thank you for your suggestions. We are very sorry for our insufficient description of the conclusion.
We have updated our manuscript by rewriting the conclusion according to the reviewer’s correct suggestions and adding the further work about the limitations and future work in Lines 418-421 of Section 5.
In summary, thank you for your suggestion. It is very important. Due to your suggestion, we have found some shortcomings in our current work. We will improve our research level and obtain more results in our current and future work according to your suggestions.
Special thanks to you for your good comments and suggestions, we hope to learn more from where you are.

Reviewer 2 Report
Comments and Suggestions for AuthorsThe article deals with the prediction of the ice cover on overhead transmission lines. This is a very topical task, as frequent and severe icing on transmission lines seriously threatens the stability and safe operation of the electricity system.
As meteorological data, stochastic in nature, require efficient pre-processing and feature extraction. The authors propose a new feature preprocessing method that integrates full ensemble empirical mode decomposition with adaptive noise (CEEMDAN) and spectral binning. A transformer model is also introduced that utilizes the extracted meteorological and icing elements by independently inserting variable tokens for each input element. The work also includes an analysis of prediction comparison results and an analysis of evaluation results to verify convergence and the advantage of the proposed algorithm compared to three benchmarks.
The presented publication represents a significant contribution to the issue of predicting the ice loading of power lines. It has a good scientific quality and is free from obvious errors, is clear, concise, and well organized.
Notes:
1) Figure 5 shows the relationship between ice thickness on the conductor and meteorological parameters. In the case of the wind, was its direction considered? Because it makes a difference whether the wind acts perpendicular to the line or is parallel to the line.
2) Please put in chapter 4 at least a short information about the wind direction.

Dear Reviewer,
We appreciate your effort in carefully reviewing our manuscript and your useful feedback. Based on your comments, we have revised our manuscript. Our point-to-point responses to your comments are given below.
1. Response to comment: (Figure 5 shows the relationship between ice thickness on the conductor and meteorological parameters. In the case of the wind, was its direction considered? Because it makes a difference whether the wind acts perpendicular to the line or is parallel to the line.)
Response: Thank you for your questions and we are very sorry for our negligence of wind direction. As stated by the reviewer , wind direction is also a factor affecting the thickness of ice covering on transmission lines. However, all the data in the paper comes from on-site monitoring data of a power grid company in a certain region of northern China. Unfortunately, due to the malfunction of the detection equipment of the power grid, the wind direction data is not complete, and we only have several months of data. Therefore, we did not utilize wind direction as input data for the proposing prediction model in our experiment. However, in future work, we will definitely incorporate wind direction data into the model to obtain more accurate prediction results.
2. Response to comment: (Please put in chapter 4 at least a short information about the wind direction.)
Response: We are very sorry for our insufficient description of meteorological parameters, especially wind direction. We have updated our manuscript by adding the explanation on the wind direction in Lines 323-327 of Section 4.1 and the further work about wind direction in Lines 418-421 of Section 5.
Once again, thank you very much for your comments and suggestions.
