Description

Technical Field

[0001] The invention relates to a control technology for automatic operation of a spillway arc gate in a hydropower plant, and in particular to a synchronous automatic operation method and system of a spillway arc gate based on segmented regulation. Background Art

[0002] As an important part of water conservancy facilities such as reservoirs and dams, the main function of the hydropower plant spillway arc gate is to discharge excessive water from the upstream reservoir area during the flood season, ensure the safety of reservoirs and dams, prevent dam collapse and flooding of power plants, and ensure the safety of life and property of people on both sides of the river. The spillway arc gate is generally installed in the gate slot of the spillway, and is driven by hydraulic cylinders on both sides to open and close in the gate slot to achieve flooding and close water storage. However, in the actual operation (remote control in the central control room), the arc gates of the spillway are often prone to deformation of the steel structure, measurement deviation of the opening instrument, etc., which often lead to the failure of the arc gates of the spillway to maintain the normal automatic operation state, and the excessive load can easily cause the hydraulic cylinder and its drive system to fail. After the arc gate of the spillway fails and stops running, it is necessary to send professionals to the site to perform manual corrections on site. In addition, when the arc gates of the spillway are working, in order to ensure the safety of the stilling pool, they need to be operated symmetrically, evenly and synchronously. If one arc gate of the spillway fails and cannot be opened and closed, the corresponding other hole will not be allowed to operate, which will greatly restrict the discharge of floods. The handling and response of the arc gates of the spillway are not timely enough, which is very likely to cause major secondary accidents due to the rising flood. Therefore, how to maximize the normal automatic operation of the arc gates of the spillway during the flood season is a problem of great concern to every hydropower plant. If the above problems can be effectively solved, it can avoid the hydropower plant's unplanned abandonment of water or failure to discharge flood water according to the prescribed flow rate, improve the reliability of the flood discharge system operation, ensure the economic operation of the unit, and lay a solid foundation for the power plant to achieve safe flood season.
