Method and arrangement for accessing SCADA data from wind turbines

摘要

The invention relates to a method for protected access to SCADA data (11) of a wind energy plant (2), and to an arrangement (1) designed to carry out this method. The SCADA data (11), together with master data (10) of the wind energy installation (2), is digitally signed and transmitted to a broker server (3), which generates a metadata record (12) based thereon and transmits it to user clients (4). If the user client (4) is interested in the SCADA data (11), the user client (4) sends the metadata record (12) back to the broker server (3) in digitally signed form. The broker server (3) responds with a likewise digitally signed delivery data record (13) comprising the metadata record (12) signed by the user client (4) and the SCADA and master data (10, 11) belonging to the metadata record (12).
