Definitions

  • the present invention relates to energy collection devices and applications for their use.
  • the present invention related to solar energy collection devices.
  • Solar cells or photovoltaic cells as they are also known, are devices used to convert solar energy into heat and electricity. Solar cells are often placed on the roofs of buildings, bridges and other structures in order to maximize the collection of solar energy.
  • Solar cells may also be used in conjunction with a variety of energy storage systems to create efficient, low pollution energy generation devices.
  • PCS Power Conversion Subsystems
  • the storage subsystem of a FES consists of a flywheel that stores kinetic energy by spinning at very high velocities (tens of thousands of revolutions per minute).
  • the FES also consists of the radial and thrust magnetic bearings, centre post, containment and other components.
  • the power conversion subsystem for all three abovementioned subsystems includes a combination of rectifier/inverter, transformer, DC and AC switchgear, disconnects, breakers, switches and programmable high-speed controllers.
  • a high speed motor/generator set is part of the power conversion system in the FES system.
  • High speed solid-state transfer switches are used in power quality applications where high switching speeds are a requirement for the ES system.
  • the control system for ES systems has three main functions.
  • the management and control of storage subsystem monitors the charge level, charge/discharge requirements, and related operations.
  • the controls associated with the PCS subsystems monitors utility power supply and switches the load between the ES system and utility supply according to a predetermined algorithm.
  • the facility control system monitors the temperature, ventilation and lighting in the facility that houses the hardware.
  • HVAC heating, ventilation and air conditioning
  • An outer drum that turns freely - this drum includes a sprocket that engages the chain. When the drum turns, the chain turns.
  • the centre shaft and weights spin as one. If they are spinning slowly enough, the weights are held against the shaft by the spring. If the engine spins fast enough, however, the centrifugal force on the weights overcomes the force being applied by the spring, and the weights are slung outward. They come in contact with the inside of the drum and the drum starts to spin. The drum, weights and centre shaft become a single spinning unit because of the friction between the weights and the drum. Once the drum starts turning, so does the chain.
  • centrifugal clutch does not use a clutch pedal for engagement and disengagement.
  • Centrifugal clutches are typically used in automotive applications. As such, they are generally mounted horizontally. There are a variety of problems present in adapting the conventional centrifugal clutch to use in flywheel energy storage systems as will become apparent from the following discussion.

  • the frame members may be constructed from any suitable material, such as, but not limited to, metal, plastic, wood and the like and may be of any suitable construction (solid, hollow, tubular, square section etc).
  • the photovoltaic cells may be connected together directly in a pyramidal shape without requiring the use of additional frame members to create a frame, hi this embodiment, the photovoltaic cells themselves would function as the frame members.
  • the solar energy collection device may be provided with one or more concentrating means in order to concentrate the sunlight that strikes the solar energy collection device.
