ENHANCING WIND FARM MONITORING WITH FIBER OPTIC

Lightning strike on wind turbine fiber optic communication box

The presented method for lightning impact localization and classification using a fiber optic current sensor network helps to detect damages caused by lightning and to monitor the blades. The ProLEC FO lightning strike monitoring system helps in the optimization of operations and maintenance procedures at the wind turbine. Vibration-resistant splice boxes with Swiss precision for extreme wind power environments. Abstract—As wind turbines are increasing both in number and in height, they are exposed to a major threat in form of lightning strikes.

Fiber optic communication and wind power

Onshore wind farm fiber optic systems must ensure reliable data transmission between hundreds of wind turbines, central control systems and energy markets, while being designed to be easy to maintain and future-proof. Wind energy communication forms the technical backbone of successful onshore wind farms and enables optimal energy yield through intelligent control and continuous monitoring. The global wind industry is fiercely battling reliability issues to keep wind turbines turning. Unlike fossil fuels, which are a limited and dimi er requires power electronics, such as rectifiers and inverters. Fiber optics (FO) technology is probably best known for use in high-speed, high-bandwidth telecommunication applications.

Commonly used fiber optic interfaces for wind turbine equipment

The main current applications of industrial fiber optic components in wind turbine systems include: ● Power electronic gate drivers for rectifiers and inverters ● Control and communication boards ● Turbine control units ● Condition monitoring systems ● Wind farm networking. VarioConnect splice boxes combine proven technology with the specific requirements of the wind power industry - for reliable. Fibre optic rotary joints are replacing electrical slip rings, promising to eliminate one of wind power's most persistent maintenance nightmares.

Principle of Fiber Optic Cable Sheath Monitoring

A new method for permanent sheath current monitoring is introduced, which uses fibre-optic distributed acoustic sensing (DAS). With the usage of insulated HVAC power cables, a comprehensive monitoring solution is becoming increasingly important – one that computes cable ratings based on thermal profiling (RTTR), detects and locates cable hot spot temperatures (Distributed Temperature Sensing - DTS) as well as cable faults. Undergrounding power lines avoids exposure to strong winds, limits the cost of damage, provides a more aesthetically pleasing vista in areas where valued, and ofers lower fault rates compared to overhead lines. On the other hand, undergrounding is expensive and introduces new hazards such as. Fiber Monitoring is a proven, pro-active, risk-reduction and asset protection approach of pinpointing fiber degradation and breaks that threaten strategic infrastructure providing service to thousands of customers. This document describes the guideline for locating the fault in optical fiber cable after installation or during maintenance of the cable.
