摘要
超导体失超会影响超导电力设备的运行 ,是超导电力技术实用化的一个重点问题。总结了超导体失超研究方面的成果 ,主要包括失超原理、失超传播特性及失超检测几个方面 ,并以超导电力设备和常规电力设备并存的超导电力系统为基础 ,从正反两方面详细分析了超导电力设备失超对系统的安全、稳定、经济运行的影响 ,介绍了超导储能、超导变压器、超导发电机的设备级失超保护方法 ,并就未来超导电力系统失超保护研究提出了参考性建议。只要采取适当的措施 ,超导电力设备失超不会给电力系统带来很大损失。
Superconductor quench will affect the operation of superconductive electrical equipment and is an impoertant problem in the application of superconductive electrical power technique.The achievements on this subject are summarized,such as quench principal,quench spreading characteristics and quench detection.Based on a superconductive electrical power system,which composes of both superconductive and normal electrical equipment, the impact of superconductive electrical equipment quench on the safety,stability and econonic operation of power system is analyzed in detail.Quench protection for superconductive energy storage device,superconductive transformer and superconductive generator is described.Some suggestions are given for further quench protection research of power system.With proper measures,superconductive equipment quench will not bring great loss to power system.
