The invention relates to the technical field of elevators, and discloses a method and device for protecting normal operation of an elevator, electronic equipment and a storage medium. The method for protecting normal operation of the elevator comprises the steps that when the elevator operates in an automatic rescue mode in a power generation mode, the real-time voltage of a bus of the elevator is monitored; judging whether the real-time voltage of the bus exceeds a preset voltage threshold or not; and when the real-time voltage of the bus exceeds a preset voltage threshold, the running speed of the elevator is adjusted so that the running speed can be reduced. According to the invention, the condition of overvoltage of the bus can be avoided by adjusting the running speed of the elevator during automatic rescue running of the elevator applying the four-quadrant frequency converter, and the implementation cost can be controlled while normal automatic rescue running of the elevator is ensured.
本发明涉及电梯技术领域,公开了一种保护电梯正常运行的方法、装置、电子设备和存储介质。本发明中,该保护电梯正常运行的方法包括:在电梯在发电模式下自动救援运行时,对所述电梯的母线的实时电压进行监测;判断所述母线的实时电压是否超过预设电压门限;在所述母线的实时电压超过预设电压门限时,调节所述电梯的运行速度使所述运行速度降低。能够在应用四象限变频器的电梯自动救援运行时通过对电梯运行速度的调节实现避免母线过压的情况发生,在实现保障电梯正常进行自动救援运行的同时,能够控制实现的成本。
