product description
MCR (Magnetic-valve Controllable Reactor) Type SVC
 MCR type SVC uses self-coupling DC excitation and limiting magnetic saturation work mode, which not only greatly reduces the generated harmonics, but also has low active loss and fast response speed. By changing the trigger angle of the thyristor in the MCR excitation system, the magnetic flux saturation degree of the magnetic control reactor core can be changed to change the reactive capacity output of the magnetic control reactor.
MCR type SVC is highly reliable, maintenance-free, and its service life is not less than 20 years. Important systems such as traction power supply network of electrified railways have been preferentially adopted; it can work in any harsh grid working environment (such as voltage waveform distortion and large amplitude fluctuations. Such as) stable, reliable work; can be directly run on any voltage level grid (6 ~ 500kV), and the installation is simple (similar to ordinary transformers), easy debugging; reactive power compensation capacity stepless adjustment, so that the best compensation effect.

Application area
1 long distance power transmission
 The power system is currently tending towards high-power, long-distance transmission, which requires the transmission and distribution system to be more efficient. Dynamic compensation can significantly improve the power transmission and distribution performance of the power system. Dynamic compensation can be installed at one or more appropriate locations on the power grid to achieve the following objectives:
1, stable system voltage;
2. Reduce transmission loss;
3, increase the transmission capacity;
4, buffer power shock;
5, increase transient stability limit.
2 coal mines
 The hoist will have the following impact on the grid during its work:
1. Cause the voltage drop and voltage fluctuation of the power grid;
2, low power factor;
3, the transmission device will produce harmful higher harmonics.
 The dynamic compensation device can perfectly solve the above problem.
3 Wind farm boost station
 The reactive power consumption of the wind farm changes with the change of wind speed. The dynamic reactive power compensation device can realize rapid dynamic adjustment of reactive power, stabilize the system voltage, increase the power factor, completely solve the problem of reactive power transmission in wind farms, and improve wind power. Field booster station ideal for power quality.
4 electric arc furnace
 Arc furnace as a non-linear and irregular load into the power grid, will have a series of adverse effects on the power grid, which are mainly:
1. The generation of high-order harmonics is a complication of voltage distortion;
2. Result in severe three-phase imbalance in the power grid and negative sequence current;
3, there is a serious voltage flicker;
4, low power factor.
5 rolling mill
 The reactive impact load of the rolling mill has the following effects on the power grid:
1. Decrease the power factor;
2, causing voltage fluctuations and voltage drops, severe electrical equipment can not work properly, reduce production efficiency;
3, Harmonic harmonics will be generated in the load transmission device, which will cause serious distortion of the grid voltage.
 Dynamic compensation can solve the above problems perfectly, keep the bus voltage stable, no harmonic interference, power factor close to 1.0.
6 Electric locomotive power supply
 The electric locomotive transportation mode has also caused serious “pollution” to the power grid while protecting the environment. The single-phase power supply of the electric locomotive causes serious imbalance of the three-phase power network and reduces the power factor, and generates negative sequence current. The only way to solve this problem in the world is to install a dynamic compensation system at an appropriate position along the railway to increase the power factor. .
