Gravity coupling flywheel combined energy storage system and operation method
The invention belongs to the technical field of energy storage, and particularly relates to a gravity coupling flywheel combined energy storage system and an operation method. The system comprises an energy storage array composed of a plurality of energy storage units, each energy storage unit comprises a basic frame, a gravity energy storage module and a flywheel energy storage module, and the gravity energy storage module comprises a first power generation electric all-in-one machine and a winch; the first power generation and electric all-in-one machine and the winch are connected with the traction rope together; the traction rope is connected with a gravity block; when the gravity block descends, the first power generation electric all-in-one machine is a generator, and gravitational potential energy of the gravity block is converted into electric energy; when the gravity block ascends, the first power generation electric all-in-one machine is a motor, and electric energy is converted into gravitational potential energy of the gravity block; when the gravity block ascends and descends, the ascending and descending speeds of the gravity block are adjusted through the flywheel energy storage module. When the gravity block decelerates, braking energy of the system is absorbed by the flywheel, and direct-current voltage is stabilized; when the gravity block accelerates, the flywheel is used for releasing energy, and the dynamic characteristic of the traction system is improved.
本发明属于储能技术领域，具体涉及一种重力耦合飞轮联合储能系统及运行方法。系统包括由多个储能单元所构成的储能阵列，每个储能单元包括基础框架、重力储能模块和飞轮储能模块，重力储能模块包括第一发电电动一体机和卷扬机；第一发电电动一体机和卷扬机一起与牵引绳连接；牵引绳连接有重力块；重力块下降时，第一发电电动一体机为发电机，重力块的重力势能转化为电能；重力块上升时，第一发电电动一体机为电动机，电能转换为重力块的重力势能；重力块的上升、下降时，通过飞轮储能模块调节重力块的上升、下降速度。在重力块减速时利用飞轮吸收系统的制动能量，稳定直流电压；在重力块加速时，利用飞轮释放能量，改善牵引系统的动态特性。
