Description

Technical Field

[0001] This utility model relates to the field of marine power supply technology, and in particular to a marine energy power supply management system. Background Technology

[0002] During navigation, ships generate electricity using diesel engines to meet their power needs. When ships are in port, they primarily rely on shore power to ensure their electricity supply. However, diesel engine power generation requires burning large amounts of fuel oil, leading to severe environmental pollution. Furthermore, the voltage supply from diesel engines is unstable due to variations in engine speed, which can easily damage shipboard electrical equipment. On the other hand, shore power supply has disadvantages such as long shore power lines, unstable voltage, and inconvenient installation.

[0003] To overcome the shortcomings of the aforementioned power supply methods, existing technologies mainly employ hybrid energy power supply systems to introduce clean energy (such as photovoltaic power). However, existing hybrid energy power supply systems only support photovoltaic power and cannot supply power from other clean energy sources (such as wind power), resulting in low utilization rates of clean energy. Furthermore, existing hybrid energy power supply systems lack input over / under voltage protection, surge protection, and leakage protection functions. Utility Model Content
