Principles of ANSVG
Static var generator is a new type of power electronics used to compensate for reactive power, harmonies, and régulation imbalances.
ANSVG is a kind of static var generator device which intégrâtes an intelligent control System. The equipment is generally put into operation in the form of a complété machine which composed of multiple ANSVG modules to meet the actual requirements of compensating for the reactive power of a larger capacity. In addition, the device also has a 7-inch LCD screen that communicates with the module in real time via the RS485 protocol, enabling users to interact with the device. The schematic is shown as bellow.
Function
1)Flexible compensation method:Compensating for reactive power from the load,filter out harmonics within 5th, 7th, 9th, 11th, and 13th;
2)Ability of managing three-phase imbalance;
3)Linear compensation,Response time ≤ 5ms;
4)Humanized human-computer interaction interface, which displays real-time power quality information of the system and the ontology. This interface has the ability to control the device remotely and easy to operate;
5)Adopt imported IGBT which has high power density and high reliability;
6)Using DSP digital control system for high speed detection and calculation;
7)With remote communication interface, real-time monitoring through PC;
8)Standard modular design which reduces lead times and increases reliability and maintainability.
