Abstract

The invention discloses an intelligent dormancy and rotation control method for a modular subway braking feedback device. When the feedback device is running, each module is controlled to be put into or removed step by step according to the real-time monitored subway braking energy and the operating priority of the modules. ; When the braking energy of the subway increases, each module is put into operation in sequence according to the operation priority; when the braking energy of the subway decreases, each module is cut off in sequence according to the operation priority. The present invention invests and removes the modules according to the braking energy of the subway, which can realize the optimization of the overall efficiency. Through the setting of the operating priority of the modules, in the step-by-step input process of the modules, the modules with high operating priority are put in first, and the In the step-by-step removal process, the modules with high priority are removed first, so as to realize the equalization of the working time of each module and improve the overall service life of the device.

Description

technical field [0001] The invention belongs to the field of subway regenerative braking feedback, and in particular relates to an intelligent dormancy and rotation control method for a modularized subway braking feedback device. Background technique [0002] The subway regenerative braking feedback device feeds back the excess energy generated when the subway locomotive brakes and brakes to the AC power grid in the way of inverter feedback and grid connection. It has the outstanding advantages of low-carbon energy saving, green environmental protection, stability and reliability, and low investment. It is the future subway Development direction of regenerative braking energy absorption. [0003] The modular subway regenerative braking feedback device has good scalability and high redundancy. When a single module fails, it will not affect the normal operation of other modules. Therefore, it is especially suitable for occasions with high reliability requirements such as subwa...
