This sounds very odd to me.
Most wind turbines built today with a capacity of over a few hundred kW are not synchronised to the grid frequency.
They run at whatever speed they can run at with the current wind speed, which is converted to DC, goes down to the root of the wind mill and gets converted back to regular 50Hz AC when it's put into the grid. They only thing that could happen there is that this converter station blows up.
Also, those modern turbines always have turnable rotors that can just be moved into a longitudinal position relative to the airflow, stopping immediately.
- hyperman1 8y agoMy knowledge of turbines is about a century out of date, so please be so good to add everything you know to this discussion. As I understand it:. It used to be that every turbine on the grid was synchronized and people found out how the grid communicated its energy behaviour by changing frequency. This happened as emergent behaviour, almost by accident. As the grid operators came to rely on it, newer technology has to emulate it. But today, most of Europe shares the same grid, which was impossible at the time. There have to exist technological advances to make this possible. And solar doesn't even have an inherent frequency, it's DC. So what you say sounds very reasonable. But I hope never to see from close by what happens if modern energy equipment fails catastrophically.
