Wind Power Early Warning System

What is early fault warning method of wind turbine main transmission system?

To accurately obtain the operational state of the main transmission system and detect its operation abnormal as soon as possible, an early fault warning method of the wind turbine main transmission system based on SCADA and CMS was proposed.

Why is early warning important for wind turbines?

Due to the limited accessibility of wind turbines (WTs) and the complexity of operation and maintenance (O&M), it is increasingly important to early warn the component faults of WTs, and the difficulties lie in balancing the comprehensiveness and delicacy of early warning.

How is early warning signal detected in a wind turbine?

Wind turbine and its monitoring variables are mapped into a complex network, where early warning signal is detected by temporal network flow entropy (TNFE) among the moni... References is not available for this document. Need Help?

Why do we need early warning system for WTS fault?

Since the early fault features implied in adjacent historical data are not fully mined, the alarm information provided by SCADA is usually not timely enough. When the alarm signal is sent, the fault is usually serious and unrecoverable [7, 8]. Therefore, it is necessary to develop an independent early warning system for WTs fault.

How does fault early warning work?

For the online fault early warning part, in Stage I, the real-time SCADA data is converted into GAF and then inputted into Model I to determine the main component fault type and the fault early warning time; in Stage II, data is converted into grayscale images, and then input into Model II to determine fault code type and early warning time.

What are the key features of early warning?

The demanded key features of early warning are the fault warning precision and the advanced warning time, in which the ‘precision’ lies not only in low false warning rate, but also in the refined location of the fault subcomponents inside the main components.
