Abstract
A system for regulating the voltage in an electrical distribution system includes a plurality of flywheels, motor/generators, and controllers. Each of the motor/generators is coupled to one of the energy storage flywheels and to the electrical supply system. The motor/generators each supply one or more signals representative of motor/generator operational parameters, and each motor/generator controllers receive one or more of the motor/generator operational parameter signals from each of the motor/generators. In response to the operational parameter signals, the motor/generator controllers each control the operation of one of the motor/generators in either a motor mode or a generate mode, to thereby regulate the electrical supply system voltage and equally share the electrical load between the motor/generators.
