ROLE-BASED ACCESS CONTROL FOR USERS IN A COMPUTER SYSTEM OF A RENEWABLE POWER PLANT

The invention relates to a method and a system for role based access control to a computer system of a renewable power plant. The users of the computer system are assigned roles defining permissions for the users accessing the computer system when the user login and the computer system of the renewable power plant is checking whether the local role permissions dataset stored at the computer system is different from a remote role permissions dataset stored on an off-site central computer system. If the local role permission dataset and the remote role permission dataset are different, the computer system of the renewable power plant is pulling the remote role permission dataset from the off-site central computer system and overwriting the local role permission dataset; ensuring that the local role permission dataset is identical to the remote role permission dataset.
