My understanding is that Loy Yang A is designed for TTHL. The problem in this event was that the boilers tripped before the turbines, I believe.

My mistake on Loy Yang not being designed for TTHL. I am getting my power stations mixed up. I have been there once in a professional capacity and it is an amazing site.
Regardless, designed for TTHL (or not), boiler trips are bad news. The crew on site did well to return the plant to service so quick.
Just to back up what you are saying, there is a SARS document on the AEMC web site that discusses some of the challenges with system restarting. It is a good read.

We are certainly in an age where there are a lot of clueless folk, with little engineering understanding, in key positions demanding changes in the grid with little understanding of the consequences. Sigh ...
