How much exposure can a radio base station have?
On the ground, in houses, and other places where people reside, the exposure levels from radio base stations are normally below 1 percent of the limits. Only in the close vicinity of the antennas can the exposure limits sometimes be exceeded.
Can flywheel energy storage improve wind power quality?
FESS has been integrated with various renewable energy power generation designs. Gabriel Cimuca et al. proposed the use of flywheel energy storage systems to improve the power quality of wind power generation. The control effects of direct torque control (DTC) and flux-oriented control (FOC) were compared.
What is flywheel energy storage fess technology?
The principle of flywheel energy storage FESS technology originates from aerospace technology. Its working principle is based on the use of electricity as the driving force to drive the flywheel to rotate at a high speed and store electrical energy in the form of mechanical energy.
How much power does a flywheel provide?
At full speed, the flywheel has 5 kW h of kinetic energy, and it can provide 3 kW of three-phase 208v power to a power load. Small versions of this flywheel will be able to operate at very high speeds, and may require the inherent low losses in HTS bearings to achieve these speeds .
