Meaning of sentences using "has/have/had been" and "is" with nouns

Question

I read some sentences where writers used nouns with has/have/had been.

What exactly does it mean?

Examples:

She has been an able administrator.
Her mother had been an American.
He has been mad at me.

What if I say?

She is an able Administrator.
Her mother was an American.
He is mad at me.

Please explain the difference.

Also when and how to use has/have/had been and is?

**has/have/had + Past Participle** combinations are used to form the Perfect tenses: Present Perfect, Past Perfect, Future Perfect. You might google for "present perfect", "past perfect" if you wish to learn more. — CowperKettle, Jan 22 '15 at 10:23
This is a very complicated topic. You may also wish to consult our long post on [*What is the perfect, and how should I use it?*](http://ell.stackexchange.com/q/13255/32). — StoneyB on hiatus, Jan 22 '15 at 12:13

You should have a look at the conjugation table of to be in a basic grammar:

Tenses I: I am, I was, I will be, I would be

Tenses II: I have been, I had been, I will have been, I would have been

After will/would follows bare infinitive or infinitive perfect.

After have/has/had follows stem form 3: been (past participle).

ELL is not a place to ask for grammar lessons. You need to consult a site such as English Club. – Jan 22 '15 at 14:22
Or simply get a grammar. – rogermue Jan 22 '15 at 15:21
