ABB is offering PTO/PTI-drives for hybrid propulsion systems through-out the power scale — Comparison of the hybrid propulsion options — Benefits — Down sides Parallel hybrid propulsion Serial hybrid propulsion Motor dimensioning for fast RPM Suits single propeller hull shape Low torque and transfer torque dimensioning No gear losses on ...

PTO简单来说，就是power take-off。 PTO模式，对于本项目来讲，就是主机在运行的时候，配套的轴发用来发电，然后电力与船舶电站并网，与两套发电机组共同供电。

Hybrid propulsion system provides a very good basis for operating ship at optimum performance. This needs to be carefully designed to match the required operational profile. It is also good to understand real requirements correctly:

ZF's compact and lightweight down-angle hybrid transmissions are perfect for fast vessels requiring high speeds and offer a suitable solution for any space requirement. The hybrid transmissions are designed for a maximum output of up to 1,940 kW (ZF 3200 A PTI) or 2,463 kW (ZF 5200 A PTI) and cover a ratio range of i=1.892 to i=4.240 or i=2.588 ...

2021年12月7日 · 船舶“混合动力”系统的运行工作模式一般情况有3种：动力输出（Power Take-off，PTO）、动力输入（Power Take-in，PTI）和动力返回（Power Take home，PTH）。 （1）动力输出（Power Take-off，PTO）是指通过轴带发电机获取动力向船舶电网供电的模式，即发电模式。 这是轴发的基本工作模式，PTO 模式的系统结构图如下（属于上述典型的船舶“混合动力”系统结构图的一部分）：

Improved energy efficiency and flexibility through hybrid marine propulsion systems. PTO-PTI solutions reduce fuel consumption and exhaust emissions at the same time. The PTO-PTI propulsion system functions as a stand-alone unit or as a support for other engine units in the ship, depending on the operating mode.

In modern hybrid propulsion systems, the inclusion of power electronics for controlling the shaft generator, using INGEDRIVETM H, enables the diesel engine and propeller to operate at variable speeds whilst maintaining the grid frequency and grid voltage fixed.

Reduced emissions and fuel consumption, as the result of reduced diesel engine´s speed following the optimization of operating modes. Quick and easy switching between the different operating modes, making the system highly flexible. Increased life cycle of gensets and propellers, given that the number of their operating hours is reduced.

Learn more about how the Variable Speed Shaft Generator (PTO/PTI) works. ABB slow speed shaft generator solutions are for low and medium voltage systems, covering powers up to 6 MW and more. The same unit can be used as a generator (PTO), booster motor (PTI) or alternative propulsion system (PTH).

2023年12月1日 · In this study, a novel hybrid system combining a vertical pile-supported comb-type breakwater (CTB) and an oscillating flap (OF) is proposed, to absorb effectively long-period waves and simultaneously extend period range of wave energy extraction. The OF is hinged in the chamber of the CTB, and the hybrid system is collectively called as CTBOF.
