SVP frequency conversion shore power supply control system

Abstract

The invention relates to the electronic field and especially relates to a power supply control system. A SVP frequency conversion shore power supply control system comprises the power supply control system. The power supply control system is provided with a power input terminal and a power output terminal. The power input terminal is connected to a rectification voltage regulation circuit. The rectification voltage regulation circuit is connected to the power output terminal. The rectification voltage regulation circuit is connected to a micro-processor system. The micro-processor system is also connected to a first current sensor used for detecting an output state of the power output terminal and a first voltage sensor. In the invention, a standard industrial power supply provided by a dock site is converted into high quality power supply which can be used by a landing ship; simultaneously, feedback information of the current sensor and the voltage sensor is used to change the output state of the power output terminal in real time so as to cooperate with different ships; and a purpose of effectively controlling the frequency conversion shore power supply is reached.

Description

technical field [0001] The invention relates to the field of electronics, in particular to a power supply control system. Background technique [0002] The purpose of the frequency conversion shore power supply is to transform the standard industrial power supply provided by the dock site into a high-quality power supply that can be used by docking ships through frequency conversion and voltage conversion, so as to realize fast and reliable power supply for docking ships and achieve the purpose of energy saving and emission reduction ; [0003] Due to the difference between the shore power supply and the ship's power grid, it is generally easy to generate a current shock when the frequency conversion shore power supply and the ship's power grid are connected to the grid. There are some high-power electrical equipment on the ship, such as ballast pumps, lubricating oil pumps, and cable winches. Wait, there will be irregular start and stop operation. When these devices start ...

Problems solved by technology

[0003] Due to the difference between the shore power supply and the ship's power grid, it is generally easy to generate a current shock when the frequency conversion shore power supply and the ship's power grid are connected to the grid. There are some high-power electrical equipment on the ship, such as ballast pumps, lubricating oil pumps, and cable winches. Wait, there will be irregular start and stop operation. When these devices start and stop, there will be a relatively large current impact on the power supply, and it will also cause a sudden drop in the power supply voltage.
