Wind Turbine Bolt Monitoring System

The Theta Wind Turbine Bolt Monitoring System is an industrial software solution specifically designed for monitoring bolts in wind turbines. Based on IoT technology and compatible with both Linux and Windows operating systems, the system supports B/S (browser/server) architecture. It communicates via fiber-optic ring networks within the wind farm to collect real-time data from turbine gateways, including bolt loosening angles and preload force. Beyond comprehensive bolt management, the system offers features such as bolt ID assignment, initial value calibration, graphical data visualization, and status alarms. This enables users to effectively monitor equipment health, prevent failures, optimize maintenance strategies, and improve the operational efficiency and reliability of wind turbines.

Key Features

Real-Time Data Acquisition & Analysis

High-precision sensors monitor critical parameters such as bolt loosening, preload force, and potential breakage. Data is stored and analyzed in real time to generate health reports, providing a complete picture of equipment condition.

Smart Alarms & Predictive Alerts

The system includes multi-level alarms that monitor critical indicators like bolt loosening and tension anomalies. When data exceeds set thresholds, alerts are triggered and sent to users, enabling early fault detection and downtime prevention.

Data Visualization & Remote Monitoring

Users can remotely access real-time and historical trend data from each monitoring point. The intuitive graphical interface allows for quick assessments and timely decision-making, with remote control capabilities supported.

Flexible Deployment & Compatibility

Supports deployment on public cloud, private cloud, or on-premise servers, and is compatible with mainstream OS platforms such as Linux and Windows. It is adaptable for both individual turbines and large-scale wind farms.

Standardized API & Secondary Development

Equipped with standardized API interfaces for seamless integration with third-party management or SCADA systems. Supports custom development to tailor the platform for specific operational needs.

Asset & Project Management

Enables multi-project management, allowing users to add, edit, or delete turbines, sub-assets (e.g., flanges), and monitoring points. The system tracks asset status, alarm history, and long-term performance data.

User & Permission Management

Supports multi-user role-based access control, ensuring that different operators or administrators have appropriate permissions to ensure system security and operational clarity.

Log Tracking & Fault Tracing

Provides detailed logs of all user operations and system events, enabling traceability, root cause analysis, and efficient troubleshooting.

Efficient Fault Prediction & Maintenance

By analyzing historical data trends, the system can identify early signs of failure. This supports predictive maintenance strategies that reduce unplanned downtime and improve equipment efficiency.

Graphical Dashboards

The system includes a rich set of visual tools for intuitive monitoring:

Bolt Status Overview

Displays the overall health condition of all monitored bolts across the turbine.

Loosening Trend Chart

Tracks bolt loosening trends in real time to identify potential risk patterns.

Preload Force Trend Chart

Monitors preload changes to ensure bolts remain within safe tension thresholds.

Bolt Distribution Map

Visualizes the spatial distribution and health of monitored bolts across the turbine structure.

Driving Intelligent Maintenance in Wind Power

The deployment of Theta’s Wind Turbine Bolt Monitoring System marks a major step in the transition from scheduled maintenance to intelligent operations in the wind energy sector. Combining proprietary sensor technology, efficient data processing, accurate remote diagnostics, and a flexible architecture, the system provides a unified smart solution. It significantly enhances the safety, reliability, and maintenance efficiency of wind turbines while supporting the broader digital and intelligent transformation of the wind power industry.
