The main idea of the paper design can be related to your outline directory, that is, the title of each short paragraph you design.

The problem encountered in the paper is that you think about the difficulty of doing this design at that time, and then think about how you solved it later. You can recall it, but pay attention to the summary of the language.

What did you learn from the design? The first is the technical problem in the electrical design of 35KV substation, and the second is the extension problem, such as the need to open up new ideas, the spirit of hard study and so on.

Actually, my friend, these things are not very difficult. The key is that you can extract the backbone and important points of this proposition. Don't worry about anything. What you have to do is to grasp the time and the consistency of these three points in expression. There is nothing to be afraid of in your defense. Just believe in yourself. Don't be nervous when you reply, but be calm. Good luck.
