Problems solved by technology

[0003] This charge and discharge control strategy requires an additional charger when the diesel generator set and the battery pack are deeply mixed for power supply. Otherwise, the charge and discharge control of the battery pack cannot be realized when the ship is running, resulting in the diesel generator set not being able to operate at the best fuel. Near the consumption point, the purpose of fuel saving and environmental protection cannot be achieved

Embodiment Construction

[0017] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0018] refer to figure 1 As shown, the charge and discharge control device of the present invention is composed of a diesel generator set 1, a controllable rectification device 2, a storage battery pack 3, a propulsion frequency converter 4 and a propulsion motor 5, and the controllable rectification device 2 is used to control the DC bus voltage and control the DC bus voltage. The bus limiter realizes the charge and discharge control of the battery pack 3; the difference between the optimal fuel consumption power of the diesel generator set 1 and the actual load power is divided by the current DC bus voltage to obtain the required charge and discharge current of the battery pack 3, plus the actual The charging and discharging current of the battery pack 3 is adjusted by PI to obtain the DC voltage given value of the controllable rectifier device 2; the...

Abstract

The invention discloses a hybrid ship charge-discharge control device. The control device is formed by a diesel generating set, a controllable rectifying device, a battery pack, a propulsion frequencyconverter and a propulsion motor; the invention further discloses the control method of the hybrid ship charge-discharge control device. By means of the control method of the hybrid ship charge-discharge control device, deep hybrid power supply of the diesel generating set and the battery pack is achieved, charge-discharge control of the battery pack can be achieved when the ship sails without needing configuration of an additional charging generator, and controlling of the battery pack can be conducted according to surplus power of the diesel generating set when the ship sails.

Description

technical field [0001] The invention belongs to the field of ship electrical control, and in particular relates to a hybrid power ship charge and discharge control device and method, which are suitable for the control of electric propulsion ships powered by a hybrid power supply of a diesel generator set and a battery pack. Background technique [0002] At present, there are more and more types of hybrid ships. The conventional practice of electric propulsion ships using diesel generator sets and battery packs is to work independently. When the battery pack is low, the diesel engine shaft generator generates power. , and then charged by the charger or directly by the shore charger. [0003] This charge and discharge control strategy requires an additional charger when the diesel generator set and the battery pack are deeply mixed for power supply. Otherwise, the charge and discharge control of the battery pack cannot be realized when the ship is running, resulting in the die...
