Konstanz Electric helps Shandong Taitong Biotechnology Industrial Park project to be put into operation and escorts green power

Guided Reading

Shandong Taitong Biotechnology Industrial Park Project was officially launched in 2020. It is a representative project of the national, provincial and municipal key medical and health industry. With the commencement of the first phase of the industrial park, a new chapter in the development of the medical and health industry will be opened. The project adopts our low-voltage APF active filter device. The excellent energy saving, stability and safety of the product make customers very satisfied, and also expand the brand influence of Konstanz Electric in the power quality industry.

Overview of Shandong Taitong Biotechnology Industrial Park Project

Shandong Taitong Biotechnology Co., Ltd. was jointly invested and established by Guochuang Taihua (Beijing) Technology Development Group Co., Ltd., Zhuhai Huiruixin Technology and national biotechnology experts. The project of Taitong Biotechnology Industrial Park is invested and constructed by Shandong Taitong Biotechnology Co., Ltd. The total investment of the project is planned to be 2.6 billion yuan, including 1.28 billion yuan in the first phase. The project covers an area of about 130 mu, with a total building area of 160000 square meters. It mainly constructs standardized three-dimensional GMP workshops, modern office buildings, research and development centers and supporting facilities. Introduce high-end experimental and production equipment at home and abroad, develop and produce QK320 monoclonal antibody injection grade drugs and series products. After the project reaches its capacity, 5 million pieces of QK320 McAb products can be produced annually, with an annual sales income of 12 billion yuan and tax revenue of more than 1 billion yuan, and more than 500 people can be employed.

Power quality problems in the process of putting the project into production

Taitong Biotechnology Industrial Park is a national, provincial and municipal key investment and construction project in the medical and health industry. It involves the R&D and production of high-tech biopharmaceuticals, which means the introduction of various advanced medical equipment, frequency converter equipment and communication equipment. Most of these equipment use advanced power electronic devices with high power capacity and high power density, which produce harmonic hazards in most medical scenarios, such as:

Medical equipment

There are a large number of power electronic components running in medical equipment, which will produce a large number of harmonics when working, causing pollution. For example, the rectifier bridge of the high-voltage rectifier in the X-ray machine will produce large harmonics when working.

Frequency converter equipment

Most of the ventilation equipment in the medical scene, such as air conditioners and fans, are inverter equipment. As a very important harmonic source, the total harmonic current distortion rate (THD-i) of the inverter reaches more than 33%, which will generate a large number of 5th and 7th harmonic currents to pollute the power grid.

Communication equipment

In most medical scenes, computer network management is introduced, in which computer equipment, video surveillance and audio equipment are typical harmonic sources. In addition, in order to ensure the stable operation of the server storing data in the computer network management system, the system must be equipped with UPS and other backup power supplies. The UPS will also generate a large number of 3rd, 5th and 7th harmonic currents when it is working.

In addition to the above three harmonic sources, lighting devices such as LED lights and gas discharge lamps in the scene will also introduce harmonic currents that cannot be ignored into the power grid. In addition to the impact and harm to the operation of power grid and equipment, the superposition of these harmonic currents on the neutral line will also cause fire hazards in the scene.

Harmonic control solution

In order to solve the hazard problem caused by harmonics, the technicians of Konstanz Electric carried out a comprehensive analysis of the site conditions on the spot, and configuredLow voltage APF active filter device.

Low voltage APF active filter

The low-voltage APF active filter device operates in parallel with the harmonic source equipment in the power grid. It can monitor the harmonic current in the power grid and filter according to the filtering target set by the user. It filters the harmonic current by injecting the current with the same size and opposite phase to the harmonic current of each frequency into the power grid. The harmonic pollution in low-voltage power distribution system is effectively suppressed, the safety and reliability of power distribution system operation are improved, and a clean, safe and reliable power supply environment is provided for the project operation of Taitong Biotechnology Industrial Park, so as to protect production equipment and improve the service life of production equipment.

Product advantages

1. High reliability, designed for industrial load, can fully meet the requirements of different working conditions;

2. The predictive control method of harmonic current is adopted, with fast response speed, strong filtering ability and small operation loss;

3. Dynamic real-time filtering of all harmonics or multiple selected harmonics, dynamic compensation of fundamental reactive power while filtering harmonics, and improvement of power factor;

4. The three-phase imbalance can be compensated to avoid the negative impact of negative sequence current on the power grid and electrical equipment;

5. The original imported IGBT of Infineon is adopted, with better product performance and more stable equipment operation;

6. Modular design and unit parallel design scheme are convenient for capacity expansion.
