Background technology
As the fast development of national economy, society are continuously increased to the demand of electric power, the continuous of power system has been driven
Development, single-machine capacity and station capacity, substation capacity, city and center of industry load are continuously increased, and allow for power train
Interconnect between system, the short circuit current level in electrical networks at different levels is improved constantly.Even so, general way is remained using open circuit
On the one hand device is cut-off to faulty line, protection power equipment, on the other hand also avoid as busbar voltage is too low and to
Family adversely affects.With the continuous improvement of short circuit current level, it is necessary to improve constantly the Breaking capacity of chopper.So
And, further the Breaking capacity of raising chopper, not only technically more and more difficult, and cost also significantly will be carried
It is high.Additionally, chopper can not be directly used in parallel.Therefore, the Breaking capacity of electric network fault short circuit current is not enough increasingly
Become the important bottleneck problem for limiting power network development.
Not enough in view of the Breaking capacity of chopper, in recent years, various methods for limiting grid short circuit electric current also begin to
It is concerned and applies.The method for limiting grid short circuit electric current mainly has：（1）Improve line voltage；（2）Untie electrical network connection, bag
Include the connection disconnected between some transmission lines of electricity or double-bus.When there is short trouble, back-up breaker can be closed and ensure confession
Electricity；（3）Improve short-circuit of power transformer impedance；（4）Installing current-limiting reactor；（5）Installing fault current limiter.However, carrying
The cost of high line voltage grade is too high；The method for untiing electrical network connection, can cause the power supply reliability of electrical network to substantially reduce；Adopt
With high-impedance transformer or current-limiting reactor be current limiting short-circuit current be also simply most most ripe scheme, but need to increase and be
System is idle and is unfavorable for Power Network Transient Stability.In order to eliminate the shortcoming of current-limiting reactor, can be electric using failure is installed in electrical network
Stream limiter this solution.Fault current limiter impedance very little under normal operation, the impedance in short trouble become big
And current limliting.The fault current limiter technology of current comparative maturity mainly has series connection current-limiting reactor, series resonance-type fault current limit
Device processed, controlled series compensation fault current limiter etc., and the fault current limiter technology for being in conceptual phase mainly applies new material
The current limiting technique of realization, including superconductive current limiter, PTC thermistor current limiter and solid-state current limiter.
In current superconductive current limiter technology, superconduction resistance-type current restrictor has obtained very big concern.Normally transport in system
During row, superconduction resistance-type current restrictor is presented no resistance state, does not have any impact on electrical network, when failure occurs, high-temperature superconductor
Body is quenched and high resistance state is presented carries out current limliting.Superconduction resistance-type current restrictor make when, typically using single or many
Superconductive tape is fabricated to noninductive disk-type winding module, and then the logical module of multiple noninductive disk-type windings is crossed connection in series-parallel and forms current limiter.By
