US Renewable Energy Project Equipped with Real Time Condition Monitoring

For one of the biggest American renewable energy companies LIOS provided its well recognized DTS system for monitoring the temperature of two medium voltage power cables directly buried coming from a wind turbine towards the substation. All asset condition monitoring data from the controller is linked in real time by means of Modbus communication protocol to the operator’s SCADA system. The company is convinced by using DTS it has a better control over the thermal cable conditions thus over the load of the power cables which let it utilize its assets more economically. This is a great step for LIOS Technology to strengthen its position in USA for temperature monitoring of power cables at wind farms together with the recently opened office in Morganville, New Jersey.

Dynamic wind farm load patterns recorded by long range DTS

The biggest Danish utility owner has successfully completed the installation of LIOS' Single Mode DTS equipment to monitor the power cable temperature of an offshore UK wind farm. This wind farm consists of 25 wind turbines and running in total 150.000 hours/year, designed for operational usage for in total 20 years. The high voltage power cable route is approx 20km long and connecting the offshore substation to a substation onshore. The DTS system provides real time distributed temperature sensing of the HV cable sections subsea and those inside the towers and ensures save and stable grid operation. Furthermore it helps activating hidden capacity reserves during dynamic transmission requests.
