Past simple has only one verb and that is in past tense. eg I arrived at the station. - arrived is past verb.
Past perfect has two verbs one is had - the past of have, and the other is a past participle. eg The train had left. - left is the past participle of leave.
Past simple and past perfect are often used together. The past perfect verb shows an action that happened in the past before another action (past simple) that happened in the past eg
The train had left when I arrived at the station.

It is the same difference as exists in English between perfect and simple verbs. A perfect verb implies past action as well as continuance in the given tense whereas a simple verb only discusses action in a given tense. For example, if I say "I have walked the dog", it means that I walked the dog prior to my current walking of the dog and that the past walking and present walking was continuous. If I say "I walk the dog", it would seem to be something that is generally something that I do, but is not a continuous action.
Simple is not a verb therefore it doesn't have a past tense. The past of perfect is perfected
"i had" is used in past tense and "i have had" is used in past perfect perspective. That is the only difference. no need to get confused.
