Hengli petrochemical is the earliest and fastest domestic implementation of the polyester chemical fiber industry chain strategy development industry leaders, actively promote the development of coordinated balanced business plate, vigorously expand upstream and downstream high-end capacity, is committed to build from "crude oil-aromatics, polyester, olefin, PTA, ethylene glycol, civil silk, industrial silk, polyester film, engineering plastics" world-class whole industry chain integration collaborative platform development mode.
Hengli refining and petrochemical integration project has been fully put into operation, and the company has achieved a strategic breakthrough in the key production capacity of refining and aromatics, and become the first enterprise in the industry with an integrated operation from the "crude oil-PX-PTA-polyester" industry chain.In addition, the rapidly promoted new production capacity of polyester, such as ethylene, PTA and polyester new materials, has been put into production in turn, building the strategic leading advantages of industrial coordination, production capacity structure quality, device scale cost, technology and process accumulation, project production speed and the development of the listing platform.As a first-class integrated electrical system solution and service provider in China, YT Electric cooperates with Hengli Petrochemical Company to ensure the safe and reliable operation of the power system through Active Harmonic Filter (AHF) and improve the automation level and stability of the petrochemical industry.
With the in-depth application of power electronics technology, the automation of the petrochemical industry constantly improve, load properties have undergone qualitative changes, the increase of nonlinear, impact load brought voltage flash, three-phase imbalance, reactive power consumption, harmonic and a series of power quality problems, affect the safe operation of the power grid, reduce production capacity.
The main harmonic sources of the petrochemical industry include frequency conversion speed regulating device of pump, uninterruptible power supply device, motor soft start equipment, new lighting tools (energy saving lamps, fluorescent lamps using electronic ballast, etc.).
Therefore, the petrochemical industry power supply scheme determines the need to achieve the following goals.Reduce the loss of transmission and distribution line, motor and transformer as much as possible; reduce the skin collecting effect of wire and cable, reduce the aging insulation layer, maintain the insulation performance of cable; reduce equipment loss, improve the service life of equipment; reduce the possibility of causing accident or expanding power failure, and ensure the safe and reliable operation of power system.
According to the characteristics of the petrochemical industry, YT Electric has proposed a customized governance plan (AHF) to ensure the continuous and reliable operation of the power distribution system with high load state for a long time and improve the stability of the production process. Because the petrochemical industry has a long production line, a wide range, a high degree of automation, and a high degree of correlation between complex devices, the production needs lead to a large number of rapidly changing impact load and non-linear load. In view of the harmonic situation of power system in petrochemical industry, YT adopts the best solution —— Active Filtering Technology.
The Active Filter device adopts advanced power electronics technology to detect the harmonics in the grid in real time, generate the reverse phase compensation current through the converter, and dynamically filter out the harmonics in the grid.
Lianyungang Hengli Petrochemical Company through 15 sets, each 300A YTPQC-AHF Active Harmonic Filter devices management, the site power quality has been well improved. The specific compensation effect is as follows:
Compensation Before Current Waveform | Compensation After Current Waveform |
Current Distortion Rate Before Compensation |
Current Distortion Rate After Compensation |
Reactive Power And Power Factor Before Compensation | Reactive Power And Power Factor After Compensation |
The successful cooperation with Hengli Petrochemical has verified the safe, reliable and efficient performance of YT Electric's Active Harmonic Filter Device.YT Electric looks forward to cooperating with more such petrochemical enterprises, adhere to optimizing the industrial structure and layout, improve the efficiency of power energy utilization, accelerate the green reform of industrial production mode, and usher in a better life for the realization of double-carbon goals.
