Description
Technical field
The present invention relates to the reactor device of a kind of reactive-load compensation, particularly relate to a kind of magnet controlled reactor.
Background technology
Magnet controlled reactor (Magnetically Controlled Reactor, MCR), as state type
One type of reactive power compensator, originates from magnetic amplifier and saturable reactor, but in structure and performance
Upper and saturable reactor has essential distinction.The technology of magnet controlled reactor is to be broken through in the former Soviet Union, and in
It is introduced into domestic at the end of last century, has that reliability is high, it is low to be lost, take up an area less and harmonic pollution is little,
Control the advantages such as easy, be widely used in the industries such as mine, metallurgy and electric power, it has also become substitute crystalline substance
Brake tube controls the main selection of reactor.
The basic functional principle of magnet controlled reactor is can be changed by the DC current in control reactor winding
Become the magnetic flux on iron core, by changing the magnetic flux passed through on core of reactor thus the saturation changing iron core,
Thus change the inductance value of reactor, in order to realize the change of output reactive power.In order to less electric current
Realizing bigger saturation, magnet controlled reactor uses local saturation technique, has an iron leg in whole excitation
The sectional area of core is reduced, thus easily reaches magnetic saturation, and other parts are all in linear zone.This
The mode of kind greatly improves the power consumption of reactor, noise and harmonic wave performance indications.The manufacturing process of MCR and change
Depressor is basically identical, its cost, manufacturability and reliability all close to transformator, easy maintenance, non-
Often it is suitably applied the occasion that the environmental suitability requirements such as power system are high.Magnet controlled reactor is except can be used for
Power system is to improve the ability to transmit electricity of electrical network, to improve grid voltage quality etc., it may also be used for industry factories and miness
Reactive-load compensation, soft starter for motor etc., there is the biggest application value.
MCR has been widely used for the industries such as electric power, mine, metallurgy at present, simultaneously along with new forms of energy row
The development of industry, in new energy power station, MCR type reactive power compensator have also been obtained and is widely applied.
But along with electrical network requirement grid-connected to new forms of energy industry improves constantly, the response time of reactive power compensator refers to
Mark requires more and more stricter.And the excitation response time of traditional MCR type reactive power compensator is longer, more
More to meet strict grid-connected requirement.It addition, along with the extension of range of application, in the face of quick ripple
The scene of dynamic load, response speed becomes the key factor of restriction MCR development.
A kind of mode improving MCR response speed at present is to improve body tap voltage, but this mode one
Aspect can only improve high-speed excitation speed, and this mode improves the resistance to pressure request to controllable devices, cuts
The weak advantage of MCR, reduces the advantage in supertension applications.Another way is then to pass through volume
The mode of a set of winding of outer increase improves response speed, however this mode add the cost of equipment with
And manufacture complexity, it is not ideal selection.
