At 5:00 am on August 20, “Mediterranean Michel Cappellini” successfully undocked from the ship’s shore power system at Berth 6 of Chuanshan Port Container Terminal, Zhoushan Port, Ningbo, and left the port at 7:00 on the same day. The cumulative power supply time of this power connection service is up to 61 hours, and the single power supply reaches 116,200 KWH, setting a record for the maximum power connection of a single ship in the domestic shore power system.

From the continuous breakthrough of the five key technology commanding heights of Huichuan’s first set of shore power model point breaking in 2016 and the arrival of shore power system, Huichuan shore power technology has opened a new era and has helped the country’s ports to achieve normal ship connection. At the same time, digital technology is integrated to create a professional operation and maintenance management system for shore power, so that the process of connecting ships is standardized and the electricity consumption data is visualized. To help customers build a good shore power system is the constant purpose of Huichuan.

Five key technologies to ensure the normalization of the ship

Perfect solution to the problem of connecting shore power to the grid in different scenarios

Inrush current suppression control technology: dual solution of software and hardware inrush current suppression, innovative “wave by wave current limitation” inrush current suppression algorithm and special inrush current suppression equipment for shore power perfectly solve the problem of connecting shore power to the grid in different scenarios.

Ensure the smooth and stable process of the ship

Stable load transfer control technology: full matching design of shipborne auxiliary engine characteristics, innovative “simulation generator differential characteristics” technology, ship grid connection, load transfer and disassembly smooth and no fluctuation, to ensure the whole process of smooth and stable ship.

Ensure the safety of shore power system connected to the grid

Intelligent reverse power control technology: special reverse power control algorithm for shore power. The reverse power generated in the grid-connected process is completely controlled by software intelligently, which directly solves the reverse power problem from the root and ensures the safety of the grid-connected shore power system.

Ensure continuous, stable and efficient side power supply

Power supply steady-state control technology: shore power supply platform products and control algorithm software, real-time analysis of shipside power characteristics, adjust the power output, ensure that the power supply always works in the steady-state mode, to ensure that the shipside power supply continuous, stable and efficient.

Flexible power supply increases energy efficiency

Shore power intelligent microgrid distribution technology:

According to the demand of berthing ship capacity, provide targeted capacity supply to the ship, and solve the problem of continuous power supply and redundancy of the shore power system connected to the ship.

Improve the composite utilization rate and efficiency, solve the port large capacity ships and small capacity ships berthing power demand problem, improve the shore power composite utilization rate and efficiency.

At present, Huichuan Technology construction port power system (including under construction) has reached 240 sets, while helping 70 port terminals to achieve normal shore power connection, more than 10,000 times of ship connection, cumulative electricity consumption of more than 50 million KWH. After rough trial calculation, the shore power system provided by Huichuan technology can reduce the annual emission of carbon dioxide 271162935.2kg, sulfur dioxide 2571100.16kg, nitrogen oxide 1845812.8kg. The reduction in carbon dioxide emissions is equivalent to the total amount of carbon dioxide released by the respiration of nearly 1 million people in an entire year.

Practicing the “green mountains are golden mountains”, fully implementing the national “dual carbon strategy”, helping customers to implement the “carbon peak, carbon neutral” work, Huichuan technology has been on the road!
