HYMSVC series high voltage reactive power dynamic filter compensation device

Short Description:

The three major indicators of power system voltage, reactive power and harmonics are crucial to improving the economic benefits of the entire network and improving the quality of power supply. At present, the adjustment methods of traditional group switching capacitor compensation devices and fixed capacitor bank compensation devices in China are discrete, and cannot achieve ideal compensation effects; at the same time, the inrush current and overvoltage caused by switching capacitor banks have a negative It will cause harm in itself; existing dynamic reactive power compensation devices, such as phase-controlled reactors (TCR type SVC), are not only expensive, but also have the disadvantages of large floor area, complex structure, and large maintenance. Magnetically controlled reactor type dynamic reactive power compensation device (referred to as MCR type SVC), the device has significant advantages such as small output harmonic content, low power consumption, maintenance-free, simple structure, high reliability, low price, and small footprint It is the ideal dynamic reactive power compensation device in China at present.

product description

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.
