- Abstract:
- A multi-criteria algorithm for voltage sag detection is presented and its performances are evaluated by means of recorded voltage waveforms (at some Medium Voltage/Low Voltage transformers) and simulated voltage/current waveforms. The algorithm is intended to detect voltage sag occurrence and to trigger the disconnection of the faulty supply network and subsequently the connection of a voltage support system. The algorithm is very convenient in terms of memory storage and computational requirements and may be implemented on low cost platforms. The results show that the time for detection is very short and always less than a quarter of the supply voltage period.
