Embodiment 1

[0045] Such as figure 1 , 4 As shown, this embodiment discloses a cooling power balance control system for refrigerated container ships, including a data transceiver module, a processing module, a temperature change and energy consumption prediction module, and a control and optimization scheduling module. in:

[0046] The data transceiver module receives information such as the running status of the refrigerated container, the ambient temperature and humidity, the running status of the fan in the cargo compartment, the wind speed, and the illuminance sent by the sensor and sends it to the processing module;

[0047] The processing module processes the received information and sends it to the temperature change and energy consumption prediction module;

[0048] The temperature change and energy consumption prediction module predicts the time and energy consumption when the refrigeration state of each refrigerated container reaches the critical temperature point, and sends it...

Abstract

The invention discloses a refrigeration power balance control method of a refrigeration container ship and a control system thereof. The method comprises the steps of: collecting the operation states of refrigeration containers, the environment temperature and humidity, the operation states of cargo compartment fans, a wind speed and illuminance; extracting and processing the received information, establishing a nerve network model of the temperature change and energy consumption prediction, and predicting the time and the energy consumption for the refrigeration state of each refrigeration container to reach a critical temperature point; combined with a diesel generator load factor-oil consumption curve and the operation states of the cargo compartment fans, establishing a multi-target power balancing and optimization scheduling module, and solving a control and optimization scheduling strategy of the refrigeration containers; and according to the control and optimization scheduling strategy of the refrigeration containers, sending a control instruction to the refrigeration containers and the cargo compartment fans. According to the invention, the unified scheduling and management of the refrigeration container refrigeration power are realized, the load power balance is maintained, the cargo loading capacity is increased or the installed capacity is lowered, and the ship construction and operation cost is lowered.

Description

technical field [0001] The invention relates to the field of refrigeration control research, in particular to a refrigeration power balance control method and a control system for refrigerated container ships. Background technique [0002] Existing refrigerated container ships control the containers independently of each other, and there is a lack of unified management of the refrigeration power of refrigerated containers on board, resulting in a large randomness in the load power change, and a large peak power may appear. The configuration of on-board refrigeration generator sets must be configured according to the maximum probability of refrigerated container refrigeration to ensure the safety of power on board. Long-term shipping practice data show that the current mainstream power station design and use have been in an unsaturated state for a long time, resulting in the safety of the on-board power system. The amount of redundancy is huge, and the system cost is much hig...
