In order to thoroughly implement the spirit of General Secretary Xi Jinping's important instructions that the economic power must be a maritime power, a shipping power, a strong country, and a strong transportation, especially shipping, and implement the outline for the construction of a strong transportation country, the port ship shore power system has become the standard of green ports, and has a significant effect on the management of port environmental pollution and noise pollution. As a leading enterprise in the inverter power supply industry, Sunland has also participated in the construction of many large-scale wharf shore power systems in China, and has become one of the enterprises with the most application cases of shore power supply systems in the industry. Among them, it has created a precedent for the application technology of shore power at dangerous wharves and the application technology of multi-machine parallel shore power.
At the beginning of 2020, the new crown epidemic swept the world, and all walks of life were affected to a certain extent, but the epidemic could not hinder China's intelligent manufacturing, nor could it stop the spirit of struggle of Senlan people. In this special period, Sunland's new shore power system - high-pressure water-cooled four-quadrant shore power system was successfully launched, which was the first in the world for this kind of shore power system, which put forward a new idea and pioneering for the design of shore power system.
The high-voltage water-cooled four-quadrant shore power supply is a new generation of high-performance variable frequency power supply system customized and developed by Sunland according to customer needs, which has the advantages of fast dynamic response, strong overload capacity, high control accuracy, smart grid feedback, etc., and the selection of system topology, control performance, functional design, and water-cooling system design are at the international first-class level. Compared with traditional shore power, the system has the following characteristics:
1. The next generation of intelligent control system: click to start to make the control simpler, the system intelligent fault judgment, intelligent report extraction, intelligent alarm and other functions are closer to user needs, humanized design, so that the system has a higher level of automation, more convenient operation, more comfortable to use.
2. Smart grid feedback: Break the traditional thinking and operate the feedback function under the four-elephant limit, making the shore power system simpler and more reliable, and truly realizing the ship's peace of mind.
3. No interference with synchronous network technology at all: The cutting process is completely smooth, providing safety guarantee for the shore power system itself and ship equipment.
4. Multiple protection technology: more perfect multiple protection functions to fully ensure the safety of personnel and equipment.
5. Advanced water-cooled heat dissipation design: the internal circulation and efficient cooling of the water system make the system heat dissipation effect better, protect the uninterrupted power supply, and the application of water cooling further reduces the impact of seaside salinization corrosion on the system, so that the system has a longer life and more stable operation.
As the only enterprise in the frequency conversion industry that has obtained the Chinese brand and China's famous trademark, Sunland is also the first enterprise engaged in the research and application of Hong Kong power system in China, with strong R&D capabilities and rich experience in the design and application of shore power system. It is hoped that in the future, the forest can work harder and make breakthroughs, and contribute to the national green port strategy!
The successful holding of the World Expo will play an important role in enhancing the confidence of the global industrial economy, demonstrating China's determination to reform and opening up, and injecting confidence and impetus into the global economic recovery.

Selection and capacity matching of inverter - Senlan
1. Select the inverter according to the load characteristics
Second, when selecting the inverter, the actual motor current value should be used as the basis for the selection of the inverter, and the extra power of the motor can only be used as a reference. Secondly, it should be fully considered that the output of the inverter contains higher harmonics, which will form the power factor of the motor.

Hope Sunland inverter EMC rules
When various factory equipment uses frequency conversion speed regulation, harmonic disturbances will be generated on the power supply side and motor side of the inverter (VFD), which will cause electromagnetic disturbance to the power supply network and other electrical equipment near the VFD. In addition, in order to ensure the long-term reliable operation of the VFD, the wiring of the VFD is very important.
