Problems solved by technology

However, for a pumped storage power station that does not require simultaneous generation and pumping, if one water inlet and outlet flow in and the other water inlet and outlet flow out under the same generation and pumping condition, the flow pattern of the water flow will become more It is more complicated, especially the uneven coefficient of flow velocity and the coefficient of flow unevenness are more difficult to meet the control requirements, and may lead to strong backflow in the reservoir area, and even the occurrence of suction vortex and other phenomena.
Therefore, the existing technology has the problem that the flow state of the water flow is relatively complicated.

Embodiment Construction

[0020] The present invention will be further described below in conjunction with the accompanying drawings and embodiments, but not as a basis for limiting the present invention.

[0021] Example. A hydropower station with the same pumping inlet / outlet layout structure, constituted as follows Figure 1 to Figure 5 As shown, including the forebay 1, the backside of the forebay 1 is provided with two anti-vortex beam sections 2 arranged side by side, and the rear side of each anti-vortex beam section 2 is sequentially provided with a trash rack 3 and a diffusion section 4; The front side of the junction of the two vortex-proof beam sections 2 is provided with a diversion wall 5 located in the forebay 1; the top and bottom of the diffusion section 4 are two-way diffusion structures. Taking the two-way diffusion structure at the top as an example, the two-way diffusion structure includes an up and down inclined diffusion structure and a front and rear tapered diffusion structure....

Abstract

The invention discloses a hydropower-station simultaneous-power-generation-and-water-pumping water inlet / outlet arrangement structure. The hydropower-station simultaneous-power-generation-and-water-pumping water inlet / outlet arrangement structure comprises a forebay (1), two anti-vortex beam sections (2) arranged side by side are arranged on the back side of the forebay (1), and a trash rack (3) and a diffusion section (4) are sequentially arranged on the back side of each vortex beam prevention section (2); a guide wall (5) located in the forebay (1) is arranged on the front side of the connection portion between the two anti-vortex beam sections (2); the top and the bottom of each diffusion section (4) are of bidirectional diffusion structures. The hydropower-station simultaneous-power-generation-and-water-pumping water inlet / outlet arrangement structure has the advantage that the water flow regime of a reservoir area of a hydropower station under the simultaneous-power-generation-and-water-pumping working conditions can be effectively improved.

Description

technical field [0001] The invention relates to a water inlet and outlet structure of a hydropower station, in particular to an arrangement structure of the water inlet / outlet of a hydropower station with the same generator and pump. Background technique [0002] The pumped storage power station is currently the most economical large-scale energy storage power source. The unit can be switched between power generation and pumping conditions and rotated for no-load standby. It has the characteristics of flexible operation and fast response. With the low consumption of incoming electricity from outside the region and the increase in installed capacity of new energy sources, sudden power imbalances may occur in the power grid. In order to effectively alleviate the sudden power imbalance in the power grid, technicians consider solving the problem by placing different hydraulic unit units of the same pumped storage power station in the working states of power generation and pumpin...
