Answer:

Nice question

Explanation:

Accordingly Raymond Murphy intermediate level book,

simple past has specific time.

Like, I went to the super market last night. simple past specific completed work having time.

I have traveled the USA two times.
no specific time.

But if you want to use past perfect tense except possession meaning ( I had a dog) you can not use past perfect tense unless there are two facts. And if two facts occurred in the past time, the first one will be past perfect tense.
Like, I had finished my usual job before I came here.
