Recently, a 2500kVA high-voltage shore power system independently developed and manufactured by our company has successfully completed production, commissioning, and delivery, and has been officially shipped to a major overseas port for operation. The successful delivery of this system marks a new milestone for our company in the field of high-end, high-power shore power equipment, further consolidating our leading position in green port power supply technology.
This 2500kVA high-voltage shore power system is specifically designed for port berthing operations of large container ships, cruise ships, and bulk carriers. The system adopts a highly reliable modular design, uses core components from top international brands, and its input and output voltage levels are compatible with mainstream international high-voltage standards. It boasts outstanding advantages such as stable output, low harmonic content, and fast dynamic response, effectively meeting all power needs of ships during berthing, completely replacing auxiliary engine power generation, and achieving "zero-emission" port operations.
This shore power system integrates several cutting-edge electrical technologies:
1/ It adopts a high-voltage 10kV, low-voltage 220V~690V, 50Hz/60Hz-1000Hz frequency conversion scheme, which can be adapted to the situation where diesel auxiliary power is turned off during ship berthing, and the entire process is powered by shore power, significantly reducing port noise and exhaust emissions, effectively saving fuel costs, and improving operational safety and environmental protection.
2/ This shore power supply features fast voltage dynamic response, low harmonics, and comprehensive protection.
3/ In the full-load motor test before delivery, all performance indicators of the system exceeded the design requirements, with excellent performance in key parameters such as temperature rise, efficiency, and output voltage accuracy.
The core technical parameters of this shore power supply are as follows:
Input voltage: Three-phase 10kV/35kV, 50Hz
Output voltage: Three-phase 220V/380V/400V/440V/460V/480V/690V
Frequency: 50Hz/60Hz-1000Hz adjustable
Output waveform: Sine wave
Waveform distortion: <2%
Power: 2500kVA
Modulation method: SVPWM modulation, high bus utilization
Inverter efficiency: ≥98.5%
Protection level: IP55 containerized mobile type

Faced with the customer's tight deadline, our company's production, technology, and quality control departments worked together collaboratively, strictly implementing the ISO quality management system. From project review, product design, component procurement, assembly and debugging to motor load testing, meticulous control was maintained throughout the entire process, ultimately ensuring the product was ready for shipment 3 days ahead of schedule, demonstrating our company's strong project delivery capabilities.
The client for this project is a key hub port in the region, experiencing continuous growth in annual throughput and increasingly stringent requirements for environmental protection and energy efficiency. The introduction of our company's 2500kVA high-voltage shore power system will significantly reduce sulfur oxides, nitrogen oxides, and carbon emissions in the port area, helping to improve the port's ESG performance and providing a solid power guarantee for building a "green, low-carbon, and smart port." It also provides a valuable reference for the transformation of other ports in the country.
During the factory acceptance phase, the client's technical team highly praised our company's product quality, documentation completeness, and technical responsiveness. Both parties reached a preliminary cooperation intention for the construction of multiple shore power systems in the future.
As a national high-tech enterprise specializing in the manufacturing of high-end electrical equipment, our company will continue to increase investment in the research and development of key shore power technologies, and improve our full range of shore power products from 200kVA to 5000kVA. We will contribute to the green and energy-saving transformation of ports worldwide with more reliable products, more sophisticated technology, and more efficient pre-sales and after-sales services, contributing Chinese strength to achieving global "dual carbon" goals.
