In order to thoroughly implement the important instructions of General Secretary Xi Jinping on "An economically strong country must be a maritime power and shipping power" and "To develop the economy, the country must become stronger, and transportation, especially maritime transportation, must first become stronger", and to implement the "Outline for Building a Strong Transportation Country", shore power systems in ports have become standard equipment for green ports, with significant effects on controlling environmental pollution and noise pollution in ports. As a leading enterprise in the variable frequency power supply industry, Senlan has also participated in the construction of shore power systems at many large domestic terminals, becoming one of the enterprises with the most successful applications of shore power supply systems in the industry. Among them, it has pioneered application technologies such as hazardous chemical terminal shore power (reported by CCTV News) and multi-machine parallel shore power (China's first set of parallel operation case).

At the beginning of 2020, when COVID-19 swept across the world, various industries were affected to varying degrees. However, this epidemic did not hinder China's innovation nor dampen Senlan people's spirit of striving forward. During this special period, Senlan's new type of shore power system - high-voltage water-cooled four-quadrant shore power supply system - was successfully launched. This type of shore power supply system is still unprecedented worldwide and has proposed new ideas and achieved pioneering success in designing shore power systems.

The high-voltage water-cooled four-quadrant shore power supply is a new generation high-performance variable frequency Power Supply System customized by Senlan according to customer needs. It has advantages such as fast dynamic response speed, strong overload capacity, high control accuracy,and intelligent grid feedback. Whether it is system topology selection or control performance,funtion design or water cooling system design, it is at the international leading level. Compared with traditional shore power systems, this system has the following characteristics:

1. New generation intelligent control system: One-click start makes operation simpler; intelligent fault diagnosis, report extraction and alarm functions are closer to user needs, with humanized design that enables the system to have a higher level of automation for more convenient operation and better user experience.

2. Intelligent grid feedback: Breaking through traditional thinking by using four-quadrant operating feedback function, making shore power system connection easier and more reliable, truly achieving worry-free ship connection.

3. Completely non-disturbance synchronous grid-connection technology: The switching process is completely smooth without impact, providing safety guarantee for both the shore power system itself and onboard equipment.

4. Multiple protection technologies: More comprehensive multiple protection functions fully ensure the safety of personnel and equipment.

5. Advanced water-cooling heat dissipation design: Efficient cooling through internal circulation of water in the system improves heat dissipation effect, ensuring uninterrupted power supply support; meanwhile,the application of water cooling further reduces the influence of coastal salt corrosion on the system,making it longer-lasting and more stable.

The successful launch of this new type of shore power supply system once again demonstrates China's rapid progress in domestic shore power technology to the world. As Senlan is not only an enterprise that has been awarded "China Famous Brand" but also "China Well-known Trademark" in variable frequency industry,and one ofthe first domestic enterprises engaged in research and applicationof portshore powersupply systems,it possesses strong R&D capabilitiesand rich experiencein designingand applyingshore powersupply systems.Inthefuture,hopefullySenlan will continue to make continuous effortsand breakthroughs,to contribute its own strengthto thenational green port strategy!
