#CMT# #/CMT# The station has a hub mass (5) held at a load-carrying equipment in a vertical day-time tower (2) e.g. mining tower opened or closed for mining raw materials such as coal, ore and minerals, deepseatedly constructed from earth's surface. A hoisting gear (11) is installed on a supporting structure above a tower opening (13). The hub mass is lifted from a lower level to a higher geodetic level by the gear for energy storage, and is moved vertically downwards for energy production such that a generator is powered for energy production and energy recovery is carried out in an electrical network. #CMT#USE : #/CMT# Hub reservoir power station for balancing variations of electrical energy in a mains power supply by transforming surplus energy into mechanical energy and storing as potential energy by modifying a position of a hub mass for power supply to industrial, trade and household applications. #CMT#ADVANTAGE : #/CMT# The station is designed such that an ecological, secure, subterraneously working and emission free energy storage system is constructed, large storage capacity is achieved by combined operation of multiple energy storage systems, and the energy storage system is provided without consumption of environmental resource e.g. pumped storage power plant, using costlier raw materials such as battery, limiting a number of charging and/or discharging cycles of the system, and without self charging and thermal loss. The storage system is provided with high efficiency of about 80 percentages, reduced operation cost, high life span and high reliability, and is automatically started during power outage, is applicable for minutes, hours and daily load balance, uninterruptible power supply, auxiliary power supply and effective power seconds reserve, and is universally applicable. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a sectional front view of a hub reservoir power station. 1 : Rock mass 2 : Vertical day-time tower 3 : Tower wall 5 : Hub mass 6 : Guiding elements 7 : Guiding rails 11 : Hoisting gear 13 : Tower opening. |
