And thirdly, a lubrication controller (41) of the lubrication control system (40) reads the output of the liquid level sensor (33) and the temperature sensor (22), runs a proportional-integral-differential control algorithm by taking the liquid level and the temperature of the lubricating oil in the gear box set by the lubrication adjustment panel (42) as control targets, automatically adjusts the electric adjustment valve (210) to stabilize the height of the lubricating oil page in the gear box at the liquid level target set by the lubrication adjustment panel (42), and automatically adjusts the oil heater (12) and the oil nozzle (32), so as to stabilize the temperature of the lubricating oil in the gear box at the lubricating oil temperature target set by the lubrication adjustment panel (42).
