Wind Turbine PD Monitoring Solution (AI-PD1000)
PD (partial discharge) is one of the most common sources of wind turbine failure
Remote and continuous wind turbine PD monitoring is crucial but challenging because of safety issues and its complexity
AI-PD1000 is the perfect solution for remote and continuous wind turbine status monitoring that can prevent catastrophic failures and save operation and maintenance costs
WHY REMOTE AND CONTINUOUS MONITORING?
Wind turbines fail at least once a year. Bigger ones fail more often.
Even catch fire sometimes.
Operation and maintenance cost a lot.
Wind turbine operation and maintenance costs
The average wind turbine fire costs $4M ~ $7M and more for offshore wind turbines.
Wind turbines fail at least once per year on average with larger ones failing more frequently
Cumulative operation and maintenance costs of a wind turbine can be 65% - 96% of a turbine's initial investment cost
The cost of unscheduled maintenance increases over time as a wind turbine ages
Failure prevention

Continuously checking wind turbine health conditions is challenging
Need to check the status when the turbine rotates at its max capacity but climbing to the nacelle on a strong windy day is dangerous (prohibited by safety protocol), particularly for offshore ones
Things can go wrong anywhere (turbine motor, AC to DC converter, inverter, and transformer), and monitoring all sub-blocks at the same time is not trivial

Phase-resolved PD (PRPD) using just one sensor
Accurate current sensing
Wide bandwidth
Sensor bandwidth = 0 Hz (DC) ~ 1 GHz
Signal processing bandwidth = 20 Hz ~ 100 MHz
Detects both currents generated by wind turbines and PD at the same time
Beyond simple magnitude reading
PD counts
Detect and analyze phases of PD and turbine currents
Phase-resolved PD (PRPD) analysis
Historical analysis
Peer analysis
Fully integrated remote and continuous monitoring and analysis
Edge data analytics using a palm-size module
-- Small in data size and Abundant in information
Key features
Everything in a palm-size box:
Digital sensor links (4 default digital PD sensors. Up to 7 sensors)
Sensor signal processing
Health condition analytics
External data links to the cloud or local network
Main power and PRPD at the same time using just one sensor
Monitor turbine motor, AC-to-DC converter, inverter, and transformer all at the same time
Anytime & anywhere access (Cloud database + Web UI)
Easy integration into any kind of custom network (local or cloud)
Edge data analytics
Continuously sending hundreds of Mbps of raw data to the cloud (or local server) is not efficient -- impractical if possible
Aizenn's palm size module locally performs data analytics -- edge data analytics
Transmit only the analytics results which are small in data size and abundant in information
Easy and convenient external data link
Because of the edge data analytics, the transmit data size is small, enabling simple and cost-effective data link options.
Wireless options -- WiFi, Bluetooth, GSM, 5G, etc.
Wired options -- Ethernet, USB, etc.
Aizenn team supports the customization of data links.
