How SVG Combines LC Reactive Compensation Applies at the Advanced Manufacturing
I. Overview
With the development of modern industrial technology, especially in the
automobile manufacturing industry, there are many high-power spot welding machines. The power factor of spot welding machines is low, and it contains a
large amount of reactive power and a small amount of harmonics, which has a
negative impact on the operation of the power system.
Load characteristics of spot welding machine: 1. The action time of spot welding machine is extremely fast, the welding
duration is hundreds of milliseconds, and the welding frequency is fast;
2. During the welding process of spot welding machine, according to the different welding materials, the welding current can reach several amperes to
thousands of amperes instantly, which has a great impact on the power grid; 3. During the welding process of spot welding machine, huge reactive
power is produced, which leads to the power factor of the grid is very low.
II. Measurement data Comparison of power grid data before and after SVG&LC is put into
operation:
III. SFR series SVG combined with LC reactive power
compensation function introduction SVG combined with LC reactive power compensation is a new type of power
electronic device for dynamic reactive power compensation. It can
compensate the dynamic reactive power in real time, which can overcome the shortcomings of traditional LC reactive power compensation and realize
reactive power compensation function. It is widely used in manufacturing, electric power, metallurgy, petroleum, port, chemical industry and mining
enterprises, etc.
1. Quick response
Fast response is realized by SVG module, Static Var Generator(SVG) fast response time <50us, full response time <15ms;
2. Good compensation characteristics
3. Good compensation effect
IV Design of SVG & LC reactive power compensation scheme
V Project summary It completely and effectively solves the rapid change of reactive power
compensation such as spot welding machines. The power factor at the incoming cabinet of each transformer meets the requirements of the national
standard, which purifies the power environment, and ensures the safe and stable operation of the equipment. Greatly improves the effective utilization of
electric energy; reduces the loss of distribution lines, increases the terminal
voltage and prolongs the service life of cables and equipment.
