Abstract By exemplifying the feeder service for the port of Kotka, this study proposed a multi-objective optimization model for feeder network design. Innovative for difference from the single-objective evaluation system, the objective of feeder network design was proposed to include single allocation cost, intra-Europe cargo revenue, equipment balance, sailing cycle, allocation utilization, service route competitiveness, and stability. A three-stage control system was presented, and numerical experiment based on container liner’s real life data was conducted to verify the mathematical model and the control system. The numerical experiment revealed that the three-stage control system is effective and practical, and the research ideas had been applicable with satisfactory effect.

By analyzing the communication principles of ControlNet and combining with the specific production process flow, the ControlNet control system has been designed. Meanwhile, the ControlNet network optimization scheme is proposed and has been applied in the actual production according to the existing ControlNet design problems. The application result shows that the network division and network key parameters setting are very effective optimization methods, which successfully solved the emerging ControlNet fault in the production process and met the control requirements. At the same time, they are worth to be consulted for ControlNet design and optimization.

Organic Rankine cycle (ORC) is recognized as a promising technology for converting the energy from low grade heat sources into electricity. From a general perspective, the ORC system mainly operates in island mode and also has a small scale power capacity. When this type of system sustains the disturbance of load reduction, the overpressure protection in drum boiler and overspeed protection in axial turbine are the two big challenges for ORC system’s stability. In the present study, the configuration type by combining the bypass system and overspeed protection control (OPC) logic is proposed in ORC system for solving these problems. Firstly, the ORC unit model consisting of the drum boiler, boiler control system, axial turbine, bypass system, turbine control system and OPC logic is established. Then, the drawback and improvements of current OPC logic in China are carried out. Finally, the simulation of this configuration type of ORC system is investigated under load reduction disturbance. The results show that the proposed configuration of ORC system has excellent performance in purpose of power system stability. The axial turbine in the simulation model operates in constant pressure mode.
