Description

technical field [0001] The invention belongs to the field of new energy wind power and photovoltaic power generation, and relates to a 50MW 110kV new energy step-up station system. Background technique [0002] New energy power generation projects such as wind power and photovoltaics are usually composed of two parts: wind power / photovoltaic field area and substation / booster station area. The electric energy generated by the new energy power generation device (wind turbine or photovoltaic module and inverter combination) in the field is boosted by the box transformer, and then connected to the supporting substation / booster station through multiple 35kV collector lines for collection / boosting Send it to the substation of the nearby power grid company in a unified way to realize the grid connection of new energy power. [0003] The 50MW 110kV new energy booster station is a relatively common booster station configuration for wind power, photovoltaic and other new energy power...

AI Technical Summary

Problems solved by technology

The differences in the main equipment selection and layout design of each design unit have resulted in different specific forms of the current 50MW 110kV new energy booster station, which cannot achieve standardized design and occupy a large space. It also brings inconvenience to the later unified and intensive operation and maintenance management
