Well' according to later information' The source of her powers is the Hogyoku, the device Urhara and Aizen made. The hogyoku makes the deepest desires of the people around him into reallity. When Aizen became the owner of it, it made his wishes come true. Back to Orihime: When she cursed with all her heart her powerlessness, the Hogyoku heard her desire and awakened her powers. I believe that the expore to Ichigo's Reiatsu also had a part in that. So she is something unique- A regular human with powers.
