舸能动力作为系统集成商，负责全船电力推进系统的整体设计与集成，核心供货及服务范围如下：
·2套800kW主推AFE变频柜、2套630kW侧推AFE变频柜及配套制动电阻柜、UPS电源，构建稳定高效的动力核心；
·690V/400V/230V全船配电板，实现电力合理分配与精准调控；
·功率管理系统（PMS），优化功率分配，提升能源利用率；
·全套系统集成服务，含电气接口匹配、系统联调（主推电机、侧推电机等由船东另行采购）。
技术亮点如下：
·AFE四象限整流技术：主推及侧推变频器均采用中车TID5000系列AFE有源前端，功率因数≥0.98，谐波畸变＜5%，满足船舶电能质量严格要求。
·全船系统集成：提供从变频驱动、配电控制到功率管理的完整解决方案，负责全船短路电流计算、谐波分析、FMEA故障模式分析及图纸送审。
·船检合规性：所有供货设备均按CCS规范设计、制造和检验，配合船厂完成系泊试验、航行试验及产品证书获取。
该项目充分体现了舸能动力在船舶电力推进系统集成领域的技术实力，特别是在AFE变频驱动、PMS功率管理、DP2系统匹配及船级社合规认证方面的专业能力，为公司后续承接高技术船舶电推项目奠定了坚实基础。
In September 2024, GN-Power signed an official contract with Blue Future (Shanghai) Marine Technology Co., Ltd. to deliver a full integrated electric propulsion system for its 100-meter deck transport vessel. Classed by China Classification Society (CCS), the vessel complies with unrestricted sea area navigation standards and meets DP2 dynamic positioning requirements, representing a high-tech special operation ship.
As the system integrator, GN-Power undertakes the overall design and integration of the vessel’s complete electric propulsion system. The scope of core supply and services is listed below:
·2 sets of 800kW main propulsion AFE frequency converter cabinets, 2 sets of 630kW bow thruster AFE frequency converter cabinets, together with matching braking resistor cabinets and UPS power supplies to form a stable and high-efficiency power core;
·Full-vessel 690V/400V/230V main switchboards to realize rational power distribution and precise regulation;
·Power Management System (PMS) to optimize power allocation and improve energy utilization efficiency;
·Full-range system integration services including electrical interface matching and overall system joint commissioning (main propulsion motors and bow thruster motors are to be purchased separately by the shipowner).
Technical Highlights
·AFE Four-Quadrant Rectification Technology Both main propulsion and bow thruster inverters adopt CRRC TID5000 series AFE Active Front End units, featuring a power factor ≥ 0.98 and total harmonic distortion (THD) ＜ 5%, fully satisfying stringent marine power quality requirements.
·Full-Vessel System Integration We deliver a complete solution covering frequency conversion drive, power distribution control and power management. Our scope covers full-vessel short-circuit current calculation, harmonic analysis, FMEA failure mode analysis and drawing submission for classification approval.
·Classification Society Compliance All supplied equipment is designed, manufactured and inspected in accordance with CCS rules. We cooperate with the shipyard to complete mooring trials, sea trials and obtain all relevant product certificates.
This project fully demonstrates GN-Power’s technical competence in marine electric propulsion system integration, particularly our professional expertise in AFE variable frequency drives, PMS power management, DP2 system matching and classification society compliance certification. It has laid a solid foundation for the company to undertake more high-tech electric propulsion vessel projects in the future.
