Description
Technical field
The invention belongs to the reactive power compensation technology field, be specifically related to a kind of many magnetic valve type controllable reactors.
Background technology
In recent years, along with China's electric power industry development speed is accelerated, also more and more higher to the needs of electric energy.Reactive power in the electric power system is not directly as the merit of actual consumption, but the conversion of reactive power will cause voltage up-down and energy loss on generating and the transmission facility.The imbalance of electric network reactive-load will cause the huge fluctuation of system voltage, can cause the damage of power consumption equipment when serious, the accidents such as system voltage collapse occur.So reactive power compensation technology is very necessary for the potentiality of the quality of power supply that improves electric power system and excavation electrical network.
At present, shunt reactor is one of modal reactive power compensator in the electric power system high pressure grade, but because of the inherent shortcoming of its existence, it is uncontrollable, and it is connected in parallel on all the time on the electrical network and will not excises, and brings negative effect for the normal operation of electrical network.When line failure, shunt reactor can the balance reactive power and limiting circuitry in switching overvoltage; When circuit normally moved, shunt reactor just played any effect, but brought on the contrary a large amount of superfluous idle to electric power system.Controlled reactor is a kind of special ultra high voltage or superhigh pressure shunt reactor, the capacity that it can the automatic smoothing ground adjusting itself along with the variation of reactive power, and can when transient process, play the effect that reduces power frequency and switching overvoltage.
The tradition controlled reactor is regulated reactance and is adopted manually control and magnetic control, manual method can be divided into again mechanical type and adjusting gapped-core type reactor, these two kinds of Regulatable reactor response speeds are slow, malfunction.The principle of magnet controlled reactor is to realize by the magnetic resistance size that the size that change adds exciting current changes iron core.Obviously, magnetic resistance is large, and inductance is little; Otherwise magnetic resistance is little, and inductance is large.The method that changes magnetic resistance has two kinds, and a kind of is that the external dc exciting current makes magnetic circuit saturated, is called the separately excited type magnet controlled reactor, and another kind is to produce the saturation that the DC control electric current changes core of reactor by self thyristor rectifier.Magnetic valve type controllable reactor (MCR) is a kind of self-excitation type controlled reactor, it is a kind of accent magnetic path type controlled reactor that is based upon on the magnetic amplification principle, its iron core is wound with two groups of windings, changes the magnetic permeability of iron core by the size of control direct current, thereby changes the size of inductance.Compare the controlled reactor of other form, magnetic valve type controllable reactor with low cost, loss is less, and adjustable range is wider, and reliability is high, and long service life surpasses 20 years usually, can be applied in the 10-750kV network system.But the magnetic valve type controllable reactor tool harmonic content of traditional structure is larger, and in the situation of not taking any measure, the harmonic wave of single-phase magnetic valve type reactor can reach 8%.And the MCR response speed of traditional structure is not high, and when capacity was larger, tap was smaller, and the response time is usually about 500ms even higher.
The superfine people of Chen Bai title be a kind of Harmonic suppression Theory of single-phase controllable reactor and realization (Proceedings of the CSEE ", 2002,22 (3)) document has proposed two groups of reactors that work in different electromagnetic parameters in parallel, by implementing to coordinate control, the harmonic wave of the generation of each reactor is compensated mutually, thereby the harmonics level of Reactor banks is reduced.This method can effectively reduce the harmonic content of single-phase magnetic valve type reactor, but cost is higher, and the control strategy complexity has increased the response time, and volume is larger, is not suitable for indoor location.
