Magnetic controlled reactors
What is MCR?Magnetic controlled reactors (MCR) is a kind of shunt reactor with adjustable capacity, which is mainly used for reactive power compensation of power system.MCR has magnetic valve to control the permeability of reactor core, which saturates the whole iron core and improves the performance greatly by changing the structure of the magnetic furnace on the basis of the traditional magnetic saturation and reactor. so as to smooth the effective inductance of electrodeless regulator. Schematic diagram is as follows:
How does MCR work ? MCR is based on the principle of DC magnetization, using the additional DC excitation magnetization reactor core, by adjusting the magnetic saturation degree of the core of MCR, changing the permeability of the core, to achieve the continuous adjustable reactance value. The shunt magnetic circuit is composed of the core in the unsaturated region and the core in the saturated region arranged alternately on the core of the reactor; the excitation magnetization of the core by the additional DC excitation current is controlled by adjusting the thyristor triggering conduction angle; the magnetization degree and the saturation region of the core in the unsaturated region and the saturation region are changed by adjusting the area or the magnetic resistance of the core in the unsaturated region and the saturation region in the shunt magnetic circuit The magnetic saturation degree of the core can realize the continuous and fast adjustment of reactance value from 1% to 100%. Combined with capacitor, it can provide positive and negative continuously adjustable reactive power, so it can control system voltage and reactive power more accurately and more quickly. Because there is no or very little impact and inrush caused by capacitor switching, the reliability and service life of the device can be greatly improved. It can compensate three phases separately, especially in the case of three-phase power imbalance.What is the function of MCR ?1. Increase the power factor and reduce the line loss caused by reactive power , improve the power quality of users.the power factor can reach the requirements of 0.90-0.99.2. Suppressing and filtering harmonics, reducing voltage fluctuation, flicker, distortion and stabilizing voltage,improve the service life of transformers, transmission lines and other electrical equipment.3.As reactive power compensation, MCR can adjust output reactive power smoothly, which has more functions than general reactive power compensation equipment.4. Reduce the impact of local power grid such as asynchronous motor start, electric arc furnace operation and improve the system security, especially for weak current network.What are the advantages of MCR?1.no action element inside, which will not impact the system;2.Stepless regulation can realize continuous compensation of reactive power;3.Safe operation, maintenance free and unattended;4.Low loss (self loss < 1%), low noise (< 65dB);5.Low active power loss;6.Small harmonic (less than 50% of similar products);7.Reliable quality, long product life (more than 25 years);8.Convenient installation and small floor area;9.Strong overload capacity, can overload 150% in a short time;10.No electromagnetic interference and environmental pollution.What kind of place use MCR ?Electrified railwayThe load of the electrified railway traction substation is transient. When the electric locomotive passes, the load suddenly appears. After the train passes, the load disappears. Using a traditional switching capacitor will cause a traction substation to switch hundreds of times every day. Action, which severely shortens the service life of electrical equipment, and the asymmetry of the electrified railway causes its negative sequence component to be very serious.Coal and ChemicalThere are a large number of intermittent impact loads such as hoists in coal enterprises, which not only has large reactive power fluctuations but also serious harmonic pollution, which easily causes damage to electrical equipment and affects the service life of electrical equipment.metallurgyThe load of rolling mill and electric arc furnace in metallurgical system is a kind of special load. It can change the load from a small value to a very large value in a very short time (less than 1s), and the frequency of change is very fast. As a result, the display instruments in these enterprises are constantly swinging at high speed.Wind farmMCR-based SVC devices are used for continuous, non-contact, and dynamic adjustment of reactive power in wind farm substations, improving the power factor of the system, quickly adjusting reactive power output, and promoting voltage recovery.Power substationThe problems of low capacitor utilization and troublesome switching management are widespread. A large number of VQC devices installed can easily cause problems such as frequent switching operations of capacitor banks and frequent on-load voltage-regulating switches, which reduces equipment life and increases safety risks.Special industrial usersTextile enterprises and picture tube manufacturers have high requirements for the quality of the products they produce and the voltage quality of the power grid. Sudden voltage drops or momentary drops will cause a large number of waste products in their products. Using MCR-type static reactive power compensation devices can Improve its voltage quality in a short time.What is MCR type SVC ?MCR type SVC is also one of the shunt reactive compensation devices. It controls the magnitude of additional DC excitation current by controlling the conduction angle of the thyristor of the excitation device in MCR, changes the permeability of the core, changes the reactance value of the reactor, changes the magnitude of the reactive output current, and changes the magnitude of the reactive compensation capacity.What kinds of MCR do we have?Oil Immersed MCR and Iron Core.
