Hpp building with staggered location of units

FIELD: construction.

SUBSTANCE: invention relates to hydraulic engineering and may be used in construction of hydraulic power plants in restricted conditions. The proposed task is solved by the fact that the proposed design of the hydraulic power plant building may locate a large number of units arranged in the horizontal plane at one elevation. The hydraulic power plant includes a turbine hall 1 and hydraulic units 2 arranged in rows. Hydraulic units 2 are arranged in one horizontal plane so that hydraulic units of the next row are placed in the gaps between hydraulic units of the previous row. Arrangement of hydraulic units in two rows, spiral chambers of which are displaced relative to each other, makes it possible to approach axes of the units towards to each other, and thus to reduce length of the HPP turbine hall. Arrangement of the hydraulic power plant building may be across the river bed or at the angle to the river bed.

EFFECT: reduced length of an HPP building results in reduction of capital intensity of the entire hydraulic engineering facility.

The invention relates to hydropower and can be used in the construction of hydropower plants in cramped conditions.

Known hydroelectric power plant, in which for placement on a short pressure front of the greatest number of units are the last rows and rows of units shifted relative to each other in horizontal and vertical planes (see SU 130411 A1, publ. 1960).

The disadvantage of this technical solution is the significant height of the building hydroelectric power plants due to the displacement of the hydraulic units in the vertical plane.

Known hydropower plant, including the engine room and the units, located in rows, and the subsequent units of the number placed in the gaps between the units of the previous row (see SU 1038410 A, publ. 1983). Such arrangement of the units in the power house allows you to maximize power generation from a single target HPS, but the height of the building increases sharply. The described scheme can be applied to create, for example, tidal hydroelectric power station, which has a large depth of laying the Foundation of the station.

The aim of the invention is to provide a building construction of hydroelectric power, with possibly large number of devices located in a horizontal plane on one of the heights of the th mark. This need arises when considering the option of building in constraint (mountain) conditions.

Below the horizontal plane of the arrangement of units you can understand the plane passing, for example, a bottom guide vanes for Kaplan and Francis turbines or axis of rotation of the feeding the turbine with vertically arranged impeller.

The location of the building of hydroelectric power station across the river means its location at an angle of 90°relative to the direction of the river.

The location of the building of the hydroelectric power station at an angle to the river channel means its location is at an angle other than 90°relative to the direction of the river.

The essence of the invention (utility model) is illustrated by drawings, where figure 1 shows a plan drawing of the location of the units, figure 2 shows a section a-a in figure 1.

Hydroelectric includes computer room units 1 and 2 with the inlet 3 and outlet 4 water lines.

Most of the dimensions in the plan element of the hydraulic turbine is a spiral chamber. The largest size it reaches when using high-pressure turbines, equipped with impeller radial-axial type. Reducing the length of the station, where the units are located in one row, it is constrained by the width of the spiral to the measures. There are a large number of sites, where the size of the building plays an important role in the overall layout diagram of the unit. This situation occurs, as a rule, in the highlands, where to locate the building HES the most difficult due to the cramped conditions of the target construction. In this case, we search for the optimal layout decisions regarding the location of the power house, where the total length of the building is a critical parameter.

The effect of this proposal is to position units in two rows, with one row of units is closer to the wall of the power house, located on the side of the upstream and the other closer to the wall, located on the downstream side; a spiral chamber adjacent in different rows of units are shifted relative to each other across the width of the HPP building and their location in the plan can be called a "checkerboard" arrangement. This location allows you to bring the axis of the units to each other and thereby reduce the length of the machine at the powerhouse. The decrease of the length of the building also leads to lower capital intensity total hydropower object.

With this arrangement, the maximum convergence of the axes of the units will be determined by the width of the suction pipe of the turbines and the thickness of the concrete wall between them. The practice of construction and operation of hydropower plants with RA the personal types of units shows the thickness "b" concrete walls (Figure 1) between the flowing parts of the suction pipe of the turbines is determined by the strength of the structure, perceiving static and dynamic loads.

The distance between the axes of two adjacent rows of units is limited by the capabilities of handling equipment, used as the main mounting element and the size of the hydrogenerator, located at higher elevations relative to the spiral chamber. The choice of the optimal distance "B" (see Figure 1) is determined by optimizing the design of the entire building HPP.

Design studies of this proposal shows that the total reduction in capital investment in the building of hydroelectric power station, based on the two-row arrangement of the units can be up to 14%.
