The invention relates to an equipment compartment frame of a power control module of a wind turbine. The frame includes a polygonal beam structure (17) in one plane and a plurality of standing beams (18) attached to the polygonal beam structure (17) at at least some of the corners of the polygonal beam structure (17). According to the invention, each standing beam (18) is attached to the polygonal beam structure (17) by means of a releasable joint (26, 27, 28). The invention also relates to methods for transporting and assembling such frames.

The invention relates to a transmission station for feeding locally provided electrical energy, in particular provided by one or more wind power installations, into a grid. According to the invention, it is proposed for a housing of the transmission station to feature a first, accessible room and a second room that is connected to the outside world by means of an exhaust pipe, with such first room and second room being connected to each other by means of a joint recess, with such control unit closing the joint recess, and with one casing of the control unit being open in the area where the recess is closed and/or showing a predetermined breaking point that is adapted to fail if an electric arc occurs inside the control unit.

Protective barriers for protecting assets (e.g., electrical power transformers and other substation components). The protective barrier may include a lower portion and an upper portion. The lower portion may include first and second laterally spaced A-frame structures having a first protective member assembly extending between aligned legs of the respective A-frame structures on one side thereof. The first protective member assembly may include a first plurality of substantially horizontally extending protective members oriented at an angle relative to a horizontal plane. The first and second A-frame structure may have a second protective member assembly extending between aligned legs of the respective A-frame structures on an opposing side thereof. The upper portion may comprise a third protective member assembly. Methods of making a protective are also disclosed.

An energy room for providing energy to a building that is physically separate from the energy room. The energy room contains on the one side service connections from public utilities and services and on the other side service connections to service lines that run to the building. The energy room becomes an energy center for the building by housing energy generation equipment and energy storage devices. The energy center generates energy that is supplied to the building, but also receives energy that is generated at the building and uses that energy to generate another form of energy and/or stores that energy to be delivered at a later time to the building.
