Jiangsu Hongling Special Steel Co., Ltd. Technical Transformation Project

Jiangsu Hongling Special Steel Co., Ltd., founded in 2007, is an enterprise specializing in the production of stainless steel products, integrating smelting, steel rolling and processing. The company mainly produces a variety of stainless steel seamless pipes, bars, plates, profiles and other products, and has technical transformation projects, committed to improving production efficiency and product quality.

Jiangsu Hongling Special Steel is currently facing serious power quality issues, mainly including insufficient compensation capacity and rapid load changes. These problems not only affect the stable operation of the production line, but also increase energy consumption and grid instability.

In response to the above problems, the company chose the comprehensive power quality management solution provided by our company, using the YDK-SVG static VAR generator and YDX series anti-harmonic intelligent capacitor integrated control solution. The specific configuration is as follows:

Product Introduction:

YDX series anti-harmonic intelligent capacitors are a new generation of reactive power compensation equipment that is efficient and energy-saving, filters harmonics, and improves power factor. They replace traditional reactive power compensation equipment consisting of intelligent reactive power compensation controllers, fuses, switching switches, filter reactors, power capacitors and other loose parts.

YDK-SVG static reactive generator is a new type of power electronic device used for dynamic reactive compensation and three-phase imbalance control. It can analyze the reactive content of load current by sampling load current, and then control and actively output the corresponding reverse reactive current, and respond quickly to compensate the reactive component in the load current to achieve dynamic tracking compensation.

After the implementation of the governance plan, the company's power quality has been significantly improved:

1. The power factor is increased to close to 1, significantly reducing grid losses and electricity costs.

2. The response speed when the load changes is faster, and the power quality is more stable, ensuring the continuous and efficient operation of the production line.

3. Harmonic pollution is effectively controlled, which prolongs the service life of electrical equipment and reduces the equipment failure rate caused by harmonics.

4. The intelligent management system improves operation and maintenance efficiency and reduces operation and maintenance costs.

This case fully demonstrates the significant advantages of the SVG+C integrated control solution in solving the problems of insufficient compensation capacity and rapid load changes. Through the effective combination of our power quality products, not only efficient reactive power compensation and harmonic control are achieved, but also outstanding results are achieved in cost control and system intelligence.
