- 摘要:
- 为解决高混合度动力系统大功率推进负载在模式切换（主要是PTH模式向主机模式切换）过程中引起的主机转速骤降等动态性能劣化问题，开展针对一典型高混合度散货船柴-电动力系统由PTH模式向主机模式切换时的系统性能优化控制技术研究，提出长延时滑摩策略、接排转速优化策略和转矩补偿策略的控制方法，通过Amesim软件搭建仿真模型并对上述控制策略进行分析，提出了适用于高混合度船舶动力系统性能优化的控制方法。结果表明，采用转矩补偿策略可以将转速超调率由原切换策略下的16.40%降低至8.62%，有效改善模式切换过程中的转速骤降问题。
In order to solve the problem of dynamic performance deterioration such as engine speed drop caused by high-power propulsion load of high hybrid power system during mode switching (mainly PTH mode switching to main engine mode), the research on system performance optimization control technology of diesel electric power system for a typical high hybrid bulk cargo ship during PTH mode switching to main engine mode was conducted. The control methods such as clutch connection time extension strategy, clutch connection speed adjustment strategy and torque compensation strategy were proposed, the simulation model was built through Amesim and the above control strategies were analyzed, and the control method suitable for the performance optimization of high hybrid marine power system was proposed. The results show that the torque compensation strategy can reduce the speed overshoot rate from 16.40% under the original switching strategy to 8.62%, and effectively improve the speed droop during the mode switching process.
