-0.9s two wind farms drop out -192MW
The fact that two wind farms that would be geographically separated drop out within 0.1 of a second indicates that a lot more was going on. Whatever caused them to drop out would also be the trigger to cause the interconnect to also drop out.
It appears to me that if you are going to overload a wind farm it will drop out hence both going at the same time followed closely by the interconnect.
