This article studies how to rapidly reduce the power grid load and to avoid the under frequency or overload of the other online generators for the dynamic positioning drilling platform in the event of a switch failure trip or the unexpected shutdown of the generator. The fast load shedding strategy based on the events has been introduced and compared with the traditional load shedding method based on frequency and available power on the basis of the platform power station that was equipped with the intelligent electronic device and IEC 61850 communication network. The results show that the fault load shedding strategy based on events has great advantages in rapid response. The fault load shedding strategy based on the events can significantly improve the stability and reliability of the platform power grid for the dynamic positioning drilling platform or ships with power grid using IEC 61850 and GOOSE communication.
