Embodiment Construction

[0055] like Figure 4 As shown, the inverter in this embodiment includes a first reporting unit 40, which is used to send a master ID (high level) and a slave ID (low level) to the host bus; a second reporting unit 42 , used to send communication information such as the capacity of the motor, the inverter power-on state, and the inverter power supply state to the communication bus; the listening unit 41 is used to listen to the level state of the host bus, that is, to listen to the parallel system Whether there is currently an inverter master in the system; the competition unit 43 is used to control the first reporting unit 40 to send the master identity to the master bus and use the inverter as the master ; Wherein, the competition unit 43 further includes a master release module 430, which is used to release the master flag of itself when the inverter in the master status loses the master status, and controls the first reporting unit 40 to send to the master bus Slave ID; t...

Abstract

The invention discloses a method and an inverter of competing for the position of host in a parallel system, and is used to solve the problem of system breakdown caused by multihost case in the prior art. The method of the invention includes: the inverters connected in parallel in the parallel system intercept the signal in the host bus, and determines whether a host exists in the system at that moment according to the intercept result; If so, the inverter is maintained at the present position; or else, the inverters send ID to the host bus one by one in delay action and the present inverter is taken as the host. The invention is applicable to parallel systems of the same capacity and different capacity, and improves the speed and success rate of the host competition in the parallel system.

Description

technical field [0001] The invention relates to the technical field of power supplies, in particular to a method and an inverter for competing for the master position in a parallel system. Background technique [0002] In an existing parallel system composed of multiple modules (such as inverters), the AC outputs of each module are connected in parallel to provide energy for the load to increase the capacity of the system or improve reliability. In order to ensure the reliable operation of the parallel system, the amplitude of the AC output of each module must be consistent, and the phase must also be synchronized, otherwise a large circulating current will be generated between each other, which will cause overload or damage to each module. [0003] In the distributed parallel system, in order to ensure the phase synchronization between the modules, it is necessary to select a certain module among the modules as the master to control the frequency source of the output volta...
