United States : Applied Materials Teaming with Central Hudson Gas & Electric to Demonstrate Superconducting Fault Current Limiter Technology in... [TendersInfo (India)]


(TendersInfo (India) Via Acquire Media NewsEdge) United States : Applied Materials Teaming with Central Hudson Gas & Electric to Demonstrate Superconducting Fault Current Limiter Technology in New York Applied Materials, Inc. today announced that it has completed the assembly of a superconducting fault current limiter (SCFCL) system for installation and on-grid testing at the Knapps Corners substation owned and operated by Central Hudson Gas and Electric Corp. (Central Hudson) in New York. This SCFCL system, which is scheduled to become operational in May 2014, is designed to help protect Central Hudson's electricity grid from the potentially devastating effects of electrical faults.



Applied is teaming with the New York State Energy Research and Development Authority (NYSERDA); Central Hudson, a New York State regulated electric and gas utility; SuperPower Inc., a manufacturer of high-temperature superconducting wire; and Three-C Electrical Co., a utility systems integrator, to complete the utility-scale implementation. System testing and evaluation will be conducted over a period of one year starting in May 2014, and the performance data will be provided to the New York State Public Service Commission.

Fault current mitigation is an increasing area of concern for utilities due to changes in power demand and the proliferation of new distributed generation sources. A fault current is an unintended, excessive current flowing through the electrical system that may be caused by various factors, including lightning or downed or crossed power lines. Fault currents can induce significant stress on critical substation equipment such as power transformers and breakers, resulting in a failure of part of the system and leading to interruption of power delivery. These destructive forces also wear out grid components causing premature failure and need for expensive capital replacements.


The SCFCL system is designed to reduce the first peak of a fault current on a power line, thereby limiting the destructive forces on the power system and improving equipment reliability. In developing its SCFCL technology, Applied utilized its high-voltage engineering experience gained in designing ion implant tools for the semiconductor industry, as well as its expertise in large-equipment systems engineering. Incorporating advanced 2G high-temperature superconducting materials, the SCFCL is designed to add essentially zero impedance during normal operation, to insert impedance in time to reduce the first peak of fault current, and to rapidly recover after a fault for subsequent operation. Depending on the specific system configuration and local operating conditions, the SCFCL has the potential to reduce the magnitude of fault currents by the desired levels, typically 50% or more.
