Comprehensive power supply system for offshore ammonia production plant

A comprehensive power supply system for an offshore ammonia production plant is characterized in that a supply platform is fixed on the sea surface through a single-point mooring device, a solar photovoltaic panel, an electrical module, a hydrogen production module and an ammonia production module are sequentially arranged on a main deck of the supply platform, and the solar photovoltaic panel is located above the electrical module, the hydrogen production module and the ammonia production module; and the low-voltage cable is connected to the electrical module. A fuel cell, a liquid ammonia storage tank and a hydrogen storage tank are arranged in a cargo hold below the main deck, and the hydrogen production module is sequentially connected with the hydrogen storage tank, the fuel cell and the electrical module through pipelines. The hydrogen production module is connected with the ammonia production module through a gas pipeline, and electric energy generated by the offshore wind driven generator is transmitt
