Abstract:
A SCADA system includes a main switching hub and a backup switching hub that relay transmission data between a wind turbine generator and terminals provided in another SCADA system and client terminals, and a network switch for performing switching between the main switching hub and the backup switching hub for relaying transmission data between the wind turbine generator and the terminals. A backup remote I/O connected to the backup switching hub causes the network switch to perform switching based on a switching command from a SCADA terminal input via the backup switching hub. This serves to solve a data transmission problem caused by a problem in a switching hub on the wind turbine generator side from a remote location.
