The embodiment of the invention provides an electric balance control method and device and a crane, and the method comprises the steps: starting a temperature adjusting device based on user operation, and determining the operation state of the temperature adjusting device; the actual power and the target power of the temperature adjusting device are obtained; acquiring the real-time current of the generator, and calculating the actual power of the generator according to the real-time current and the rated voltage of the generator; calculating a generator rated power corresponding to the generator based on the operation state; calculating a power limit value of the temperature adjusting device based on the actual power and the target power of the temperature adjusting device and the actual power and the rated power of the generator; and controlling the temperature adjusting device to execute the power limit value so as to enable the crane to reach electric balance. According to the process, the operation state of the temperature adjusting device is determined, then the power limiting value of the temperature adjusting device in the corresponding operation state is calculated, and the power limiting value is executed, so that the crane reaches the electric balance state, the refrigeration effect of the temperature adjusting device is improved, and the refrigeration cost is saved.

    本发明实施例提供一种电平衡的控制方法、控制装置及起重机,该方法包括:基于用户操作启动温度调节装置,并确定温度调节装置的运行状态;获取温度调节装置的实际功率和目标功率;获取发电机的实时电流,根据实时电流和发电机的额定电压计算发电机实际功率;基于运行状态计算发电机对应的发电机额定功率;基于温度调节装置的实际功率和目标功率、发电机实际功率和额定功率计算温度调节装置的功率限值;控制温度调节装置执行功率限值,以使起重机达到电平衡。该过程通过确定温度调节装置的运行状态,进而计算温度调节装置在对应运行状态下的功率限值,并执行功率限值,使得起重机达到电平衡状态,提高了温度调节装置的制冷效果,并节约了制冷成本。
