Structural modules for layout of modular power plants are disclosed. The structural modules comprise a substation module and a power house module, basically formed by platforms having stringers and crossbars designed for the mounting of containment sheets. Both modules include interconnections including, for example, projecting tabs for the mechanical mounting of fixation elements enabling the connection between the modules and the mounting of columns, crossbars and lifting frame so as to form a structural skeleton suitable to contain the canopies, hinged doors and sliding doors and other mechanical structures making up the spatial areas designed for the installation of various equipment, such as a group of generators, fuel tanks and tanks for containment of liquids, motors, busbars. The substation module forms a support base whose stringers and crossbars are lined with containment sheets which, in turn, are secured by welds.

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 structures 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 barrier are also disclosed.

A container energy storage system is provided, including a container, a plurality of functional assemblies, and a splitting plate, wherein the splitting plate has a connecting port electrically connected to the functional assemblies. The container includes a hollow main body having an opening and two doors pivotally connected to the hollow main body. The functional assemblies are disposed in the hollow main body, and the splitting plate is disposed between the functional assemblies and the opening. When the doors are in a closed position, the doors cover the opening.

Systems, methods, and building block modules for modular power generation facilities are disclosed. A method of erecting a modular power generation facility includes producing a plurality of primary modules, each including a housing adapted from an intermodal shipping container having posts, rails, and sills connected together by shipping container corner castings; shipping the primary modules, which include gen-set modules and a switchgear module, to an installation location; positioning the primary modules in a vertical stack; attaching the primary modules to one another in the vertical stack; interconnecting the engine-generators of the one or more gen-set modules with the switchgear of the switchgear module; and operating the engine-generators and the switchgear to provide electricity to a transformer connected to the switchgear in response to a power load demand. The shipping, positioning, and attaching steps are carried out with engine-generators and switchgear operatively installed in the interior of the primary modules.

Systems, methods, and building block modules for modular power generation facilities are disclosed. A modular power generation facility includes a plurality of primary modules and a control system. Each primary module includes eight primary corners and an interior space. The modules are positioned in a vertical stack and are attached together to form a substantially modular enclosure for the generation of electricity. The modules include gen-set modules, each having an engine-generator and a fuel tank disposed in the interior, and a switchgear module having switchgear ganged to the gen-set modules. The control system communicates with the gen-set modules to coordinate the engine-generators as a unit and to control the loading of each of the generators in response to a power load demand. The control system is disposed in one or more of the primary modules with at least part of the control system being disposed in the switchgear module.

Systems, methods, and building block modules for modular power generation facilities are disclosed. A multi-stack modular power generation facility includes first and second pluralities of primary modules and first and second control systems. The first modules are positioned in a first stack to form a first vertical enclosure; the second modules are positioned in a second stack to form a second vertical enclosure; and the first and second modules each include gen-set modules, each with an engine-generator, and a switchgear module ganged to the gen-set modules. Each control system communicates with the respective gen-set modules to coordinate the engine-generators as a unit and to control the loading of each of the generators in response to a power load demand. The second plurality of primary modules are disposed immediately adjacent the first plurality of primary modules such that the second vertical enclosure abuts the first vertical enclosure.

A test cell (10) for containing equipment (12) subject to pressure testing comprises a plurality of metal plate wall panels (14) and a mesh roof panel (16) formed from mesh strands (26) of a high strength material. Each wall panel has a lapped connection (18) with an adjacent wall panel. The mesh panel (16) may be formed from a ballistic fabric, and the mesh strands (26) may be wire, rope and braid of steel, metal, plastic, natural or composite fibre, or a combination thereof. In the event of a pressure failure of the equipment (12) under test, the roof panel (16) captures fragments of the equipment while allowing the dissipation of pressure shock waves through the apertures (28) in the mesh. The lapped connections (18) between wall panels (14) result in increased friction between adjacent wall panels (14) and thus an increase in the strength of the connection when subject to pressure shock waves.

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.
