What is the difference between a shunt and a series connected micro-SMES system?
In a shunt connection system, the micro-SMES system is connected in parallel with the electric utility and responds rapidly (less than 4ms) to any disturbance in the quality of the utility power. This configuration provides better efficiency and lower costs with rapid response to customer needs. A series connection micro-SMES system is connected directly to the utility line and operates continuously. This configuration provides continuous support and permits the micro-SMES system to inject voltage and current without separating from the utility. Having the ability to provide either shunt or series connected solutions enables American Superconductor to provide the right solution for each customer.
