Fault diagnosis of floating offshore wind farms, a benchmark case study
IFAC PAPERSONLINE(2023)
摘要
Operation and maintenance costs of floating offshore wind farms (FOWFs) can be reduced by considering appropriate fault detection and isolation (FDI) and fault-tolerant control methods. This paper introduces a FOWF benchmark with the capacity to recreate common fault scenarios on the subsystems composing the turbines. Additionally, the paper proposes a FDI strategy as an example case, based on nonlinear parity equations, obtained from structural analysis and non-faulty data, with an adaptive threshold generation mechanism. The proposed FDI approach is assessed using the benchmark case study, showing that most of the faults can be effectively detected, while showing to be insensitive to the electric generator faults.
