Equipment renewal and new quality productivity ,FGI was invited to participate in the 16th petrochemical (safety, environmental protection, energy saving, equipment) enterprises to Shanghai research and exchange meeting

On May 22, FGI was invited to participate in the "16th petrochemical (safety, environmental protection, energy saving, equipment) enterprises to Shanghai research and exchange meeting".

CAI Lei, representative of FGI, made a keynote report on "FGI Petrochemical Industry Comprehensive Solutions" at the meeting, focusing on "energy saving and carbon reduction, autonomous control, equipment renewal, and promoting new quality productivity", focusing on FGI solutions and typical cases in the petrochemical industry.

As early as 1999, FGI began to serve petrochemical enterprise customers, and today, FGI has grown into a full value chain petrochemical and hydrogen production integrated solutions provider.

Characteristics of electricity use in petrochemical industry

1. High reliability requirements and many important loads.

2. Power grid quality requirements are high, high precision equipment.

3. A large number of motor loads, energy saving, soft start.

4. Nonlinear load, rectification, shock load.

FGI solution

With power quality control as the center, centralized control is carried out by configuring reactive power compensation devices or energy storage, or local compensation is carried out by using frequency converters with special functions.

1. High voltage frequency inverter with reactive power compensation (inverter +SVG integrated machine)

 The frequency converter makes soft start, runs to the rated frequency and then switches to the power frequency, and the whole start process is smooth and no impact.

During power frequency operation, the system has a low power factor. The traditional way is to configure a soft start system and a set of SVG or use synchronous motors, but this configuration leads to higher costs and lower system reliability.

Considering the above situation, the high voltage variable frequency soft start system is adopted, which has both variable frequency soft start function and power frequency reactive power compensation function.

2. The application of low voltage frequency inverter on oil drilling rig - top drive.

Support Profinet communication, seamless replacement of imported brands.

High performance low frequency control features.

Frequency conversion with soft torque and reverse torque release function to protect drill pipe.

Modular design, easy repair and maintenance.

3. Inverter + energy storage solution

Suitable for important loads with speed regulation requirements, such as gas fans.

Parallel energy storage battery on the inverter, which is used as the inverter under normal circumstances.

After power failure, the inverter is powered by the battery to ensure that important loads do not stop.

4. Large capacity inverter solution

Smooth start and speed regulation to ensure power factor and grid quality.

5. Reactive power compensation scheme

Install compensation equipment in the substation to centrally control the power quality of the entire line.

Reduce circuit loss, improve system power factor, and compensate cable reactive power.

Stabilize the grid voltage, raise or lower the system voltage, and stabilize the output.

Fast dynamic compensation, dynamic adjustment according to the set target.

FGI has been deeply engaged in the petrochemical industry for many years, and configured different solutions for global petrochemical user enterprises according to different use environments and different on-site needs. FGI will unswervingly practice the mission of state-owned enterprises, be a good benchmark flag in the new era to promote the energy revolution and ensure national energy security, and use high-quality products and services to help the petrochemical industry reduce costs and increase efficiency, equipment update, digital intelligence upgrade, and green development. To promote China to achieve the goal of "double carbon" and build a new energy system to make greater contributions.
