Fault Current Limiting Superconducting Transformer

Project data has not yet been submitted.

Abstract

SuperPower and its partners originally intended to design, develop, manufacture, install, and demonstrate a Smart Grid compatible Fault Current Limiting (FCL) Superconducting transformer on a live grid utility host site. However, when the transformer manufacturer decided to leave the project, the team effort was refocused to develop the key technologies necessary to produce a FCL Second Generation (2G) High Temperature Superconducting (HTS) transformer commercial prototype.

The technology portfolio includes a completed FCL HTS transformer design, proven integrated FCL operation, 2G conductor bonding to a stronger substrate material, 2G conductor to bushing terminations, ac loss mitigation and improved 2G conductor performance, piece lengths and cost improvements.

As of October 2015, the prototype FCL HTS transformer design is complete, the integrated FCL operation has been tested and confirmed using a winding design created for a commercial superconducting FCL transformer, 2G conductor bonding to a stiffer substrate has been perfected for long lengths and the 2G conductor to bushing termination technology has been developed. 2G conductor performance and piece lengths have doubled without the loss of high-end current carrying capacity, resulting in the expected conductor cost benefits.

AC loss mitigation techniques have been tested and more are being developed in an attempt to reduce the heat load generated by the fields surrounding the windings inside of the transformer during operation.
