About 60% of new wind turbines being installed today use electric pitch control systems. In this Tech Chat we discuss the operational and safety importance of wind turbine pitch systems and how supercapacitors have several advantages over batteries in these systems...
LICAP's UC and LIC products can last for 10-15 years with no required maintenance. The TI bq25570 device harvests power in the microwatts to milliwatts range, from a variety of DC power sources. This device includes a programmable maximum power point tracking (MPPT) sampling network to optimize, for example, solar generated power for ultracapacitor charging.
The LC0800-380-ASW features 1M cycles lifetime, 10 years calendar life, low self-discharge, no thermal runaway, and high power density.
LICAP Technologies has partnered with Windurance LLC to develop an ultracapacitor retrofit solution to replace the existing battery-based energy storage and charger system in GE 30Nm & 20Nm wind turbine pitch battery boxes. It is designed as a “drop in” replacement not requiring any modification to the pitch control system box or operating system.
