📖 Introduction
This repository implements the sub-health diagnostic framework for offshore wind assets under the “Clark Paradigm”.
Unlike traditional black-box prediction models, this project establishes an “Electromagnetic Ledger” system. By conducting a real-time audit of the 1st-20th order harmonic fingerprints across the generator, converter, tower-base switchgear, and remote collector cables, it achieves a paradigm shift from “stochastic state prediction” to “deterministic causal auditing”.
Core Philosophy: Anomaly = Physical Reality – Causal Expectation (Δ = Physical Reality − Causal Expectation).
📁 Repository Structure
To ensure the transparency and reproducibility of our research, the supporting materials for this paper are organized as follows:
figures/: Contains all high-resolution figures, architectural diagrams, and result charts presented in the manuscript.data/: Contains the corresponding datasets (raw and processed) used to generate each figure. Researchers can use this data to independently verify the causal auditing results.
🛠️ Technical Architecture
This platform adopts a distributed hardware topology, decoupling the perception layer from the audit layer:
- Perception Layer (Field Layer): MCU nodes deployed inside the turbine and at the substation inlet execute high-frequency sampling at 10.24 kHz and local FFT extraction.
- Audit Layer: Edge hosts perform feature decoupling and causal mapping via a Recursive Least Squares (RLS) engine and Multi-Head Attention mechanisms.
🚀 Key Features
- Causal Auditing Engine: Utilizes the RLS operator to dynamically track the dielectric drift of assets, superseding simple threshold-based alarms.
- Frequency-Selective Sovereignty:
- 5th/7th Harmonics: Locks onto the health state of core power devices within full-scale converters. Precisely captures switching characteristic degradation induced by IGBT junction temperature elevation, dead-time drift, or gate drive delays, while also serving as an early diagnostic indicator for the capacitance decay of AC/DC-side filtering capacitors.
- 11th/13th Harmonics: Probes the impedance evolution trajectory of long-distance subsea collection cables. Deeply analyzes distributed capacitance/inductance drift and high-frequency resonance point shifts triggered by “Water Treeing”, microscopic insulation dampness, and physical strain of cables caused by subsea currents.
- 17th+ Harmonics: Captures feature shifts induced by transformer winding mechanical loosening or magnetic circuit saturation. Furthermore, prolonged spectral imbalance in this range imposes cumulative dielectric stress, serving as a latent indicator for potential partial discharge (PD) activities.
- Ultra-low Latency: The single-iteration computation time for the 21-dimensional causal vector is < 5ms, fully meeting the real-time requirements of 50Hz power infrastructure.
- Game Theory Decision Optimization: Introduces a Nash Equilibrium model to balance generation revenue, failure risks, and O&M costs, maximizing residual asset value.
📊 Performance
Under extreme aerodynamic turbulence (e.g., sudden wind speed shifts), the error of traditional LSTM models may surge to 25%. In contrast, this framework, through rapid self-calibration, strictly restricts the audit residual Δ to within 5%.
