Abstract

The invention provides an expansion device of a wind turbine generator system. The expansion device comprises a tower and a first fixed pile; and the tower is connected with the first fixed pile. Theexpansion device is characterized by further comprising a truss tower, a connecting piece, an anchor bolt, a second fixed pile, a flange, a first tower and an expanded wind turbine generator system; the truss tower is connected with the tower through the connecting piece; the tower is positioned in the truss tower; the bottom of the truss tower is fixedly connected with the second fixed pile through the anchor bolt; the flange is arranged at the top of the truss tower; the first tower is arranged on the flange; and the expanded wind turbine generator system is arranged on the first tower. Theexpansion device solves the problems of low efficiency and high cost in expansion of a traditional wind turbine generator system.

Description

technical field [0001] The invention relates to the technical field of wind power generation, in particular to a capacity expansion device for a wind power generating set. Background technique [0002] At present, the operating time of wind turbines installed on the grid in my country has reached or approached the design life of wind turbines. Some wind farms have long operating hours, and most of these wind turbines are in poor health and have a high failure rate. It has It has caused great difficulties for some wind farms in terms of economy, safety, and operation. The technical transformation of old wind farms is an urgent task. In order to make full use of the rich wind energy resources of the old wind farms, the old wind farms that have been in operation for many years and have good conditions should actively carry out technical transformation, and replace the small-capacity fan units with large-capacity advanced units to create better economic benefits and social benefi...
