The invention discloses a gravity energy storage method utilizing an obsolete wind power main engine and a wind tower, and relates to the field of electric power recovery. Redundant electric energy of a power grid is transmitted to a motor, then the energy is transmitted to a steel wire rope reel through a transmission, a balancing weight is lifted to a certain height through the steel wire rope reel, and the redundant electric energy is converted into gravitational potential energy. When electricity is needed, the balancing weight falls to drive the steel wire rope reel to rotate, the steel wire rope reel drives the generator to generate electricity, and gravitational potential energy is converted into electric energy. 一种利用淘汰风电主机及风塔的重力储能方法，涉及电力回收领域。主要是将电网多余的电能传输至电动机，在通过变速器将能量传送到钢丝绳卷筒上，在通过钢丝绳卷筒将配重块提升到一定的高度，将多余的电能转换为重力势能。当需要用电的时候配重块下落带动钢丝绳卷筒转动，钢丝绳卷筒带动发电机发电，将重力势能转换为电能。
