The invention discloses a
tidal current energy
water turbine array flow field sensing and
intelligent control system, which relates to the technical field of ocean
renewable energy sources and comprises a flow field sensing module, an array state monitoring module, an
intelligent control module, a data storage and analysis module and an
emergency response module. The flow field sensing module comprises a dynamic calibration sub-module and a short-term prediction sub-module, and equipment such as an acoustic Doppler
current meter is adopted; the array state monitoring module comprises a
fault grading diagnosis sub-module; the
intelligent control module comprises a wake flow avoidance sub-module, a
yaw self-adaption sub-module and a
power optimization sub-module, and adjustment is achieved through combination of a PLC and a PID. The data storage and analysis module adopts a mode of combining local
solid-state storage and cloud, and BP and LSTM models are built in the data storage and analysis module; the
emergency response module can dispose six types of scenes in a grading manner. The flow field sensing error is effectively reduced, the array
generating capacity standard-reaching rate is improved, the fault
response time is shortened, the operation and maintenance cost is reduced, the grid-connected stability is enhanced, and the comprehensive energy efficiency is improved.
