HOW THREE BATTERY TYPES WORK IN GRID-SCALE ENERGY STORAGE How three battery types work in grid-scale energy storage systems. A typical lithium-ion battery system can store and regulate wind energy for the electric grid. Back in 2017, GTM Research published a report on the state of the U.S. energy storage market through 2016. The study projects that by 2021 deployments of stored energy — a GE LAUNCHES CYPRESS ONSHORE WIND PLATFORM FOR INCREASED AEP GE Renewable Energy launched its new onshore turbine platform, named Cypress, and the next model from that platform, GE’s 5.3-158 turbine. The platform advances the proven technology of GE’s 2 and 3-MW fleets, which serves an installed base of nearly 20 GW. It also uses architecture and innovations from the 4.8-158 turbine introducedin 2017.

HOW ARE ENCODERS USED IN WIND TURBINES? A common application is inside the turbine hub on pitch control units. Encoders are mounted behind pitch motors and brakes or directly engage the blade crown gear. Shafted encoders are picked for these applications as well as hollow-shaft devices. Of the recent encoders, one version for generators is intended for harsh conditions.

INTRODUCTION TO WIND TURBINE GEARS AND GEARBOXES Gears & Gearboxes 101. A gearbox is typically used in a wind turbine to increase rotational speed from a low-speed rotor to a higher speed electrical generator.
