Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of monitoring systems, in particular to a marine wind power electrical protection monitoring system. BACKGROUND

[0002] Marine wind power refers to establishing a wind power plant in a coastal area with a water depth of about 10 meters to convert wind energy into electrical energy. Compared with land-based wind power plants, the main advantages of marine wind power plants include not occupying land resources, being basically unaffected by topography, having higher wind speed, more abundant wind energy resources, larger single machine capacity, and higher annual utilization hours.

[0003] The marine wind power device needs to be equipped with an electrical protection monitoring system for controlling, protecting and monitoring electrical energy when in operation.

[0004] First, the electrical energy generated by marine wind power is transmitted through submarine cables. In order to ensure the normal operation of the cables, they need to be regularly maintained. Since the cables are buried in the seabed, workers need to use detection tools to test them one by one during maintenance. When a cable is abnormal, a maintenance tool needs to be used to locate the approximate position of the abnormal cable. The positioning steps are complex and require a lot of troubleshooting time, reducing the maintenance efficiency.

[0005] Second, the marine climate changes very quickly, and changes in the climate have a great impact on the entire wind power generation system. However, the existing wind power system cannot be warned in advance before the climate changes during operation, which causes the system to be damaged when the climate changes, and thus needs to be shut down for maintenance, reducing the utilization rate of the wind power system.
