Provided are a method for a multi-machine frequency converter generating a synchronization signal, and a multi-machine frequency converter. Provided is a method for a multi-machine frequency converter generating a synchronization signal; said multi-machine frequency converter comprises a master control unit and M1 controllable execution units requiring synchronization; the M1 execution units share a common DC bus, and M1 is an integer greater than 1; the master control unit initializes the relevant parameters of the M1 execution units, and said parameter initialization comprises initializing each system clock and the distributed clocks synchronized by a selected reference clock; after the parameters are initialized, the master control unit sends the initialization data to the M1 execution units, configures an associated register used for synchronized data transmission, and activates the synchronized clock unit of the execution unit, causing the execution unit to generate a synchronization signal. The solution provided by the embodiments of the present invention is conducive to improving the synchronized operation of multi-machine frequency converters. |
