Technology for robust, low-latency frequency and phasor estimation and evaluation with a real HV short-circuit event

With the increasing share of decentralized generation, the handling of faults requires additional attention, which is why fault-ride-through simulations are required in several countries for grid connection above a certain power. The scenarios are severe voltage dips caused by short circuits in the high-voltage grid and elimination after 60-150 ms. The aim is to prevent such an event from leading to a cascading failure of a significant proportion of decentralized generation and a subsequent imbalance between generation and consumption.
