Working principle of MCR type SVC The MCR type dynamic reactive power compensation device (SVC) is mainly composed of three parts, FC filter system, MCR thyristor controlled magnetron electric hanger system and control protection system. The FC filter system is used to provide capacitive reactive power and filter harmonics; the MCR thyristor-controlled magnetron reactor system is used to balance the inductive reactive power generated by load fluctuations in the system. By adjusting the trigger angle of the thyristor, the control The current flowing through the reactor achieves the purpose of controlling reactive power. The dynamic reactive power compensation device MCR-SVC device changes the reactive power (inductance) of the reactor according to the change of the reactive power of the load. After the MCR-SVC is put into operation, it dynamically tracks how the power of the load changes, the power factor is always kept at the set value, and the voltage hardly fluctuates, so as to achieve the purpose of reactive power compensation and filtering, so as to suppress the system voltage fluctuation caused by load changes and Flicker.
