High-reliability floating-type offshore wind measurement mobile platform wind-solar storage DC power system and control method

Abstract

The invention discloses a high-reliability floating type offshore wind measurement mobile platform wind-solar storage DC power system and a control method, and belongs to the fields of ship and oceanengineering and new energy application. The system adopts an annular DC bus, and comprises a power generation system, a measurement system and a monitoring system. The power generation system comprises four identical wind-solar storage power generation devices which are respectively connected in parallel to a DC bus through solid-state circuit breakers, wind power generation units, photovoltaic power generation units and energy storage units of the wind-solar storage power generation devices; and the monitoring system comprises a local monitoring center and a satellite communication unit. According to the invention, the system employs the four identical wind-solar storage power generation devices, so when one or more power supply units break down or wind power generation and photovoltaic power generation are insufficient during normal work, the remaining systems can form a one-stage micro-grid or two-stage micro-grid structure through on-off control over a solid-state circuit breaker,and the high-reliability power supply of a platform power system is ensured.

Description

technical field [0001] The invention relates to the fields of ships and marine engineering and new energy applications, in particular to a high-reliability 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 wind energy. In view of the construction needs of offshore wind farms, through the real-time measurement, acquisition and transmission of wind, waves and currents in the target sea area, the wind energy assessment of the enrichment degree and distribution of wind energy resources in the early stage of offshore wind farm construction can be realized, and the optimal layout of wind farms can be optimized. The optimal design of the fan has important engineering research and development significance. [0003] At present, the wind tower-type wind measur...

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
