The present invention relates to a fiber optic ring network communication method for a tram hybrid energy storage system, comprising: a controller generates a power-on signal according to a received power-on instruction, and sends it to a first main control unit; the first main control unit Obtain the lithium battery module status information of all lithium battery modules at all levels in the first and second ring networks according to the power-on signal, generate the first energy storage device status information, and send the first energy storage device status information and power-on signal to the second main control unit; the second main control unit obtains the supercapacitor module state information of all supercapacitor modules at all levels in the second secondary ring network according to the power-on signal, and generates the second energy storage device state information; the second The main control unit sends the state information of the first energy storage device and the state information of the second energy storage device to the controller; the controller generates control instructions according to the state information of the first energy storage device and the state information of the second energy storage The power supply output control of the main control unit and the second main control unit.
Description
technical field [0001] The invention relates to the field of communication technology, in particular to an optical fiber ring network communication method for a tram hybrid energy storage system. Background technique [0002] In recent years, the rapid development of trams has brought great convenience to people's travel. However, frequent starting and braking of trams will lead to fluctuations in the voltage of the traction network, which is not conducive to the safe operation of the train, and will seriously affect the quality of power supply. [0003] There are many energy storage facilities applied to trams, which can be divided into two types: energy type and power type. The energy density of the battery is relatively large, which can meet the system's requirements for high energy, but the internal electrochemical reaction is carried out, so the power density is low and the response speed is slow. Physical changes are carried out inside the supercapacitor, which has h...
