A high-reliability floating offshore wind-measuring mobile platform wind-solar-storage DC power system and control method

Abstract

A high-reliability floating offshore wind-measuring mobile platform wind-solar-storage DC power system and control method, which belong to the field of ships and ocean engineering and new energy applications. The system uses a ring-shaped DC bus, including a power generation system, a measurement system, and a monitoring system. The power generation system includes: four identical wind-solar-storage power generation devices connected in parallel to the DC bus through solid-state circuit breakers, the wind power generation unit, photovoltaic power generation unit, and energy storage unit of the wind-solar-storage power generation device, and the monitoring system includes a local Monitoring center, satellite communication unit. The system uses four identical wind-solar-storage power generation devices. When one or more power supply units fail or wind power generation and photovoltaic power generation are insufficient during normal operation, the remaining systems can form a first-level micro-system by controlling the switch of the solid-state circuit breaker. Grid or two-level micro-grid structure to ensure highly reliable power supply of the platform power system.

Description

technical field [0001] The invention relates to the fields of ships and ocean engineering and the field of new energy applications, in particular to a highly reliable floating offshore wind-measuring mobile platform wind-solar-storage DC power system and a control method. Background technique [0002] Renewable energy is of great significance to the sustainable development of mankind, and the fastest growing renewable energy in the world is none other than wind energy. For the construction needs of offshore wind farms, through real-time measurement, collection and transmission of wind, waves, and currents in the target sea area, the wind energy evaluation of the enrichment and distribution of wind energy resources in the initial stage of offshore wind farm construction is realized, and the optimal layout of wind farms is realized. The optimal design of fan and fan has important engineering research and development significance. [0003] At present, wind tower-type wind-meas...

AI Technical Summary

Problems solved by technology

[0003] At present, wind tower-type wind-measuring platforms are generally used in the initial stage of offshore wind farm construction. As offshore wind power develops from shallow seas to deep seas, there are technical difficulties and time costs in the construction of wind-measuring towers, and later operation and maintenance are more difficult.

Its construction cost and operation and maintenance cost are high, and it is vulnerable to typhoon
