Abstract： A vessl uses a common paralleling scheme for multiple generators sharing a single paralleling module.The generators can normally paralel before maintenance，but after repairs， the speed sensitivity becomes inconsistent， and the speed control parameters of the paraleling module cannot match the speed response characteristics of all generators simultaneously， making paralleling difficult or impossible.Without altering the original hardware，a speed control instruction window is added in the software.For each generator， the window size is adjusted according toits speedsensitivityoptimizing the effectivenesofthe speed controlinstructions，allowing all generators to paralel smoothly.This method provides a new approach for automatic near-synchronization paralleling of generators in similar power stations.

Key words： generator paralleling module; command window; optimization
