In book 6, why did Scrimgeour station Aurors at Hogwarts Castle to protect the students?
Did he not know that Aurors are not powerful enough to stop Lord Voldemort himself?

While not definite proof of Scrimgeour's thinking, dialogue from both Dumbledore and Voldemort imply that Aurors can stop or at least affect Voldemort.
At the confrontation at the Ministry in Order of the Phoenix, Dumbledore says:
"It was foolish to come here tonight, Tom," said Dumbledore calmly, The Aurors are on their way-"
Voldemort replies:
"By which time I shall be gone, and you dead!"
Dumbledore feels the Aurors can deal with Voldemort and Voldemort, instead of saying, "I can deal with them after you are dead" is planning on being gone.
So to me, the conclusion is that Dumbledore has confidence and Voldemort is reluctant about confronting multiple Aurors. Scrimgeour may have the same thoughts.
They were the best that he had and they would at least slow Voldemort down if not scare him off.
Auror is the occupational title of any witch or wizard serving as a member of an elite unit of highly-trained, specialist officers tasked with upholding the law and protecting the magical communities in their respective countries from large-scale threats
Also, it seems like Voldemort didn't expect to be able take them down all at once:
"But Thicknesse is only one man. Scrimgeour must be surrounded by our people before I act. One failed attempt on the Minister's life will set me back a long way."
What I get from this quote is that if the security was heightened at the ministry Voldemort wouldn't be able to deal with it, or he would consider it a major nuisance. Another quote that reinforces this is:
"It was foolish to come here tonight, Tom," said Dumbledore calmly. "The Aurors are on their way-"
Furthermore, when Fudge and the others appeared at the end of the fight at the ministry Voldemort instantly Disapparates.
"I saw him, Mr. Fudge, I swear, it was You-Know-Who he grabbed a woman and Disapparated!"
Now this might have been an attempt to conceal his cover but I doubt it, if he knew that anyone had seen him he would know his cover was blown.
Indeed, Scrimgeour probably thought that aurors could provide protection from Voldemort. This can be seen from the end of Half-Blood Prince when Scrimgeour directly offers Harry auror protection:
Scrimgeour hesitated, then said, in what was evidently supposed to be a tone of delicacy, “The Ministry can offer you all sorts of protection, you know, Harry. I would be delighted to place a couple of my Aurors at your service — ”
Harry, though, seems to agree with you that such protection would be futile, as illustrated by his response to Scrimgeour:
Harry laughed. “Voldemort wants to kill me himself, and Aurors won’t stop him. So thanks for the offer, but no thanks.”
