Cabinet-type Advanced Static Var Generators offer high-capacity reactive power compensation for industrial applications. These systems, housed in robust cabinets, provide dynamic and precise correction of power factor fluctuations, improving system stability and efficiency. Utilising advanced DSP+CPLD digital control and three-level topology technology, they deliver rapid response times (<10ms) to varying load demands. Modular design enables flexible capacity expansion through parallel connection of multiple units. Key features include forced-air cooling, comprehensive protection features (overvoltage, undervoltage, overcurrent, etc.), and remote monitoring capabilities. Available in various kvar ratings and voltage levels to suit diverse industrial power systems.

● Use DSP+CPLD all digital control core, three-level topology technology, advanced reactive power detection algorithm and PWM control strategy to achieve dynamic and accurate compensation of reactive power.
● Adopt modular design, which facilitates parallel connection of multiple modules, takes small space and is easy to maintain.
● The structural design of independent air ducts and independent warehouses ensures the stable operation of the equipment.
● Carry out full-range dynamic compensation for inductive reactive power and capacitive reactive power, and solve the three-phase unbalance problem at the same time.
● The dynamic response speed to the load is at the millisecond level, which can achieve dynamic and accurate compensation for the reactive power of impact loads.
Applications:
Cabinet-type Advanced Static Var Generators find application in industries requiring high-power, stable reactive power compensation. Common uses include:
● Heavy Industry: Steel mills, cement plants, and other heavy industrial processes benefit from improved power quality and reduced energy consumption.
● Oil and Gas: Maintaining stable power in demanding oil and gas extraction and processing environments.
● Mining Operations: Ensuring reliable power delivery to mining operations, even with fluctuating loads.
