The invention discloses a shore power supply reverse power control method, a shore power supply reverse power control device and electronic equipment. The electronic equipment comprises a memory and a processor, the device comprises a detection unit, a calculation unit and an adjustment unit; and the method comprises the steps that the output voltage and the output current of a ship generator are acquired; on the basis of a ship generator equivalent model, the excitation electromotive force of the ship generator is calculated according to the output voltage and the output current; and the amplitude, frequency and phase of the output voltage of the shore power supply are adjusted according to the excitation electromotive force, so that the output voltage of the shore power supply is consistent with the excitation electromotive force of the ship generator. According to the technical scheme, the influence of reverse power impact can be avoided to the greatest extent.
Description
technical field [0001] The present application relates to the field of ship electrical technology, and in particular to a method, device and electronic equipment for controlling reverse power of shore power supply. Background technique [0002] When the ship is docked, diesel generators are usually used to generate electricity to meet the energy demand of the load on the ship. At the same time, a large amount of greenhouse gases will be emitted, causing serious pollution to the port environment. As the state pays more and more attention to port energy conservation and emission reduction, it is required that ships be powered by shore power during berthing to reduce environmental pollution. [0003] The shore power supply can usually output power at two frequencies of 50Hz and 60Hz to meet the power supply needs of domestic and foreign ships. When the shore power supply is integrated into the ship generator grid, if the voltage amplitude, frequency, and phase of the shore pow...
