When the frequency reaches its minimum or maximum level, there is a risk of failure of transmission lines. Thus, the breakdown of transmission lines due to over or under frequency is called Power Grid Failure. … becomes the cause of grid failure, due to excessive load on the transmission lines.
What happens when a power grid collapses?
In the large-scale interconnected power network, when the power network failure occurs, the system will redistribute the power flow, if not treated, the overload lines or transformers will be removed, which may cause a series of chain reactions, or even system collapse, resulting in power grid blackout.
