Abstract:The selection of synchronization point is closely related to the main electrical connection and operation mode.The power of the assembling units fluctuates from 9 to 30MW, in the waste incineration power plant.For these small-load plants, which main electrical connection has its own characteristics, comparing with the large power plant, and the corresponding selection of synchronization point is also considered from different angles.Combined with practical engineering examples, this thesis introduce the design thought of selecting synchronization point , and presents the author’s own viewpoint.
