摘要: A subterranean energy storage system configured to store and subsequently release potential energy. Storage of potential energy is achieved by the transfer of a pseudo fluid from a first storage tank to a second storage tank located above the first storage tank, and is subsequently released by the transfer of the pseudo fluid from the second storage tank to the first storage tank. To transfer the pseudo fluid between the first and second storage tanks, the subterranean energy storage system comprises at least one continuous conveyor mechanism extending through at least one transport shaft, wherein the at least one continuous conveyor mechanism comprises a plurality of vessels arranged along a length of the continuous conveyor mechanism. The subterranean energy storage system further comprises an energy transfer means operably connected to the at least one continuous conveyor mechanism to transfer power to and from the subterranean energy storage system.

摘要: A power generation system includes a wind power generation device, a control device, and a power supply target. In power generation system, control device performs power conversion to a power generated by wind power generation device, and supplies the converted power to a power supply target. Control device has a reference map for controlling a power conversion device of the control device. Reference map is a map indicating a relationship between an input voltage to the control device (power conversion device) and an output power from the control device (power conversion device). When a start condition is satisfied, control device executes correction control for correcting reference map, and searches for a point at which an output power of power generation system is maximized while shifting the output voltage of a generator by MPPT control. Control device corrects reference map on the basis of a result of the search.

摘要: A maglev generator assembly has a main axle extending through a casing. The main axle has its two ends magnetically levitated by maglev supports, and has its lateral side magnetically levitated by maglev bearings. A generator is configured on the main axle, which includes at least a rotating disc as rotor, with multiple inductive magnets circularly arranged around the rotating disc, and a number of coils fixed around the main axle as stator. A top end of the main axle is coupled to a transmission mechanism, which in turn is coupled to a fan unit or a motor as power source. The fan unit or motor drives the main axle, as well as the rotating disc to spin, and electrical current is induced as the inductive magnets rotates relative to the coils. The main axle is fully magnetically levitated and its rotation undergoes minimum friction to achieve high efficiency.
