Abstract

The invention discloses a wind generating set with a heat pump self-deicing system and a working method of the wind generating set, and belongs to the technical field of wind power generation. Blades are connected with a hub, the hub is connected with a low-speed shaft, the low-speed shaft is connected with a gear transmission system, and the gear transmission system is connected with a generator high-speed shaft and a heat pump loop high-speed shaft. The generator high-speed shaft is connected with a generator, and a generator cooling heat exchanger is arranged in the generator. The heat pump loop high-speed shaft is connected with a compressor of the heat pump circulation loop. A heater and a deicing fan are arranged on a blade deicing circulation loop, and the blade deicing circulation loop communicates with a blade deicing device. A blade tip thermodetector is arranged on each blade. The heat pump circulation loop and the blade deicing circulation loop exchange heat in a blade deicing heat exchanger in an alternating mode, and the heat pump circulation loop and an external cooling loop exchange heat in the generator cooling heat exchanger in an alternating mode. According to the wind generating set with the heat pump self-deicing system and the working method of the wind generating set, the overall energy utilization rate of the wind generating set can be increased, the power generation efficiency of the wind generating set is improved, and good application prospects are achieved.

Description

technical field [0001] The invention belongs to the technical field of wind power generation, and in particular relates to a wind power generating set with a heat pump self-deicing system and a working method thereof. Background technique [0002] Wind power generation is a low-carbon and near-zero-emission power generation method, which can convert wind energy into electrical energy, thereby providing clean and renewable electricity for the grid. The wind turbine captures wind energy through the blades, and connects the generator through the transmission mechanism to convert mechanical energy into electrical energy. [0003] In the actual operation of the fan, there will be many problems. When the temperature is low in winter, the blades are prone to freezing, and a heat source needs to be provided in time for deicing; while the fan is running, the temperature inside the engine room, generator, etc. is high, and a cold source needs to be provided to cool down the inside of...
