Hydraulic continuous variable speed system having hydraulic and pneumatic speed controls and a method of use

A hydraulic continuous variable speed system has a turbine output shaft and electrical generator input shaft and comprises:

• a hydraulic system having first hydraulic chamber linked to the turbine output shaft and a second hydraulic chamber linked to the electrical generator input shaft, the first and second hydraulic chambers in hydraulic communication with each other, the first and second hydraulic chambers for macro level speed adjustment of the electrical generator input shaft;
• a pneumatic system having a first pneumatic chamber linked to the turbine output shaft for producing compressed air and storing it in at least one storage tank, a second pneumatic chamber linked to the electrical generator input shaft and the at least one storage tank for one or more of micro speed adjustment of the electrical generator input shaft, braking of the electrical generator input shaft, and direct drive of the electrical generator input shaft, and
• a controller for monitoring the output of an electrical generator connected to the electrical generator input shaft, comparing the output to a load/line of an electrical distribution grid, and adjusting the speed, including braking to a full stop, of the electrical generator shaft based on measurements of the load/line of the electrical distribution grid using one or more of the hydraulic system and pneumatic system to manage power supplied to the electrical distribution grid.
