An Integrated Wind Forecasting Method Based on Offshore Wind Farm Operation and Maintenance

Abstract

The invention belongs to the technical field of offshore wind power, and particularly relates to an offshore wind plant operation and maintenance based wind integrated forecasting method. The offshorewind plant operation and maintenance based wind integrated forecasting method includes a screw blade, a mounting frame, a motor, a rotary shaft, a bevel gear I, a bevel gear II, a rotary rod and a speed control tube, wherein the mounting frame is arranged at the right end of the screw blade, a mounting plate is in sliding connection above the inner part of the mounting frame; the lower end of themounting frame is fixedly connected to the upper end of a supporting rod; the lower end of the supporting rod is fixedly connected with a balance frame; the lower side of the left end of the mountingplate is fixedly connected with the speed control tube; a spiral slot is formed inside the speed control tube; a rotary shaft is rotatably mounted in the spiral slot; blocking blocks are symmetrically and elastically connected in upper and lower walls of the left end of the rotary shaft through springs; the outer surface of the middle part of the rotary shaft is fixedly connected with the bevel gear I; and the right end of the rotary shaft is rotatably connected to the left end of the motor. The offshore wind plant operation and maintenance based wind integrated forecasting method is mainly used for solving the problem that the motor inside is excessively heated to catch fire as rotation speed of the screw blade is too quick while offshore wind power of an offshore wind plant in the priorart is relatively great.

Description

technical field [0001] The invention belongs to the technical field of offshore wind power, and specifically relates to an integrated wind forecasting method based on the operation and maintenance of offshore wind farms. Background technique [0002] Offshore wind farms mostly refer to offshore wind power with a water depth of about 10 meters. Compared with onshore wind farms, the advantages of offshore wind farms are mainly that they do not occupy land resources, are basically not affected by terrain and landforms, have higher wind speeds, larger unit capacity of wind turbines (3-5 MW), and more annual utilization hours. However, the construction of offshore wind farms is also technically difficult, and the construction cost is generally 2 to 3 times that of onshore wind farms. From a global perspective, since the 1990s, offshore wind power has been explored for more than ten years. , the technology has matured day by day. By the end of 2006, the global installed capacity...

Problems solved by technology

The present invention is mainly used to solve the problem that the internal motor overheats and catches fire when the offshore wind farm in the prior art tends to cause the spiral blade to rotate too fast when the offshore wind is strong
