  • Utility scale electric energy storage system
    Patent number: 8952563
    Abstract: A potential energy storage system incorporating multiple track mounted shuttle units having motor/generator drive bogies and structure with an integral transfer mechanism for removably carrying energy storage masses from a first lower elevation storage yard to a second higher elevation storage yard employing excess energy from the electrical grid driving the motors, removing the masses in the second storage yard for energy storage, retrieving the masses and returning the masses from the second storage yard to the first storage yard recovering electrical energy through the generators.

  • Network Protection for Power Spot Networks
    Publication number: 20120267896
    Abstract: A power supply system having a spot network is disclosed. The spot network may include first and second power output lines, and first and second accessory power circuits connected in parallel to the first and the second power output lines, respectively. Each of the first and the second accessory power circuits may have a transformer and a circuit breaker connected together to protect the spot network by coordinating impedance of the transformer with trip characteristics of the circuit breaker.
