Leine Linde Systems has introduced IPMS, a their new ice detection system for wind turbines. Conventional ice sensors warn against ice after it has already formed, IPMS relies on a preventive system.
IPMS detects potential ice formation at an early stage, and prevents elevated levels of ice on the rotor blades by enabling the wind turbines to react appropriately to the weather situation. Based on the EE33 humidity/temperature measurement system the IPMS ice detection system monitors weather conditions based on multiple parameters. The integrated sensor system detects ambient conditions which can cause frost to form at the installation site, and immediately sends an “Ice” warning via e-mail including a report. The owner or operator can then visually inspect the turbine via smartphone or computer using the air-conditioned network camera connected on-site. The IPMS can be installed on the nacelle roof/weather mast of a wind turbine, either by the wind turbine manufacturer or retrofitted on-site by a service provider. Depending on the wind farm layout, one or more IPMS units can be used to control an entire wind farm. Besides the EE33 humidity/temperature measurement system, the IPMS includes a network dome camera with a zoom function which swivels 360°, a spotlight for night time operation, a compact cabinet incl. a 5.7” touchscreen, a dual-LAN router, an SD card for data recording and the necessary remote maintenance, operation and configuration software.
