INPSVG low-voltage static var generator

 

 

Operating principle

The basic principle of INPSVG is to connect the voltage type inverter to the power grid in parallel by reactor to absorb or generate reactive power required rapidly through adjusting the amplitude and phase position of output voltage on AC side of inverter, so as to realize the purpose of adjusting reactive power rapidly and dynamically. As an active type compensation device, it can not only track and compensate the impact reactive current of the impact load, but also track and compensate the harmonic current

Overload capacity: 120%

Multiple operating mode: parallel operation

Installation mode: rack type, wall mounting type

Cooling mode: forced air cooling

Temperature requirements: -15°C〜+40°C, the daily average temperature is not higher than 35°C

Humidity requirements: 15%〜90% (when temperature is 20°C) RH, attention shall be paid to condensation during operation under different temperature and humidity conditions

Altitude: 2000m

Protection class: IP2X

 

 

Performance advantages

■ It can provide continuous, smooth, dynamic and fast reactive power compensation from inductive to capacitive;

■ The controllable current source type compensation device based on IGBT inverter does not cause harmonic amplification and resonance, it is insensitive to system parameters, and has good safety and stability;

■ Not only does not generate harmonics, but also has the function of harmonic compensation;

■ The response speed is fast with a response time of no more than 5ms, which can effectively suppress flicker in the distribution network;

■ Modular design is used, with compact structure the unique cooling channel for good heat dissipation effect and simple wiring, which greatly saves assembly time and space;

■ Various installation modes including horizontal type or vertical type, etc., the installation mode is flexible;

■ The capacitors, inductors and other components in INPSVG all adopt advanced technology and production process, so that the electromagnetic noise during operation is significantly reduced and the operating loss of the complete machine is less than 2.5%;

■ Be provided with restart function after fault recovery;
