Abstract

The invention discloses a pumped storage model test downstream water tank capable of simulating wave water level fluctuations, comprising a traction control system, a flow control system, a water tank main body, an overflow pipe and a walking corridor. The traction control system is composed of motor support frame, telescopic device, PLC controller, signal line, flat water tank, rollers, guide rail and retractable bellows. The flow control system is composed of a PLC controller, a water pump, a water supply flow regulating valve, a water discharge flow regulating valve, a water supply and discharge pipeline and a circulating water channel. During the model test, the PLC controller controls the telescopic device through the stroke signal to drive the horizontal tank to move up and down, thereby realizing the sinusoidal and random fluctuations of the water level in the downstream water tank along with the horizontal tank. The invention is suitable for seawater pumped storage model power stations and conventional model pumped storage power stations with large water level fluctuations, to conduct model test research on transition processes such as large fluctuations, small fluctuations, hydraulic disturbances and other related issues under wave disturbance environments.

Description

technical field [0001] The invention belongs to the technical field of pumped storage power station model tests, and more specifically relates to a pumped storage model test downstream water tank capable of simulating wave water level fluctuations, which is used to study the effect of wave disturbance environment on large Effects of transition processes such as fluctuations, small fluctuations, hydraulic disturbances, and other related issues. Background technique [0002] my country is rich in seawater resources and has many islands. The development and application of renewable energy in coastal cities and islands urgently needs energy storage technology. Seawater pumped storage power plants can not only effectively utilize seawater resources, but also have the advantages of traditional pumped storage power plants. Therefore, seawater pumped storage technology needs to be researched and applied urgently. [0003] The seawater pumped storage power station uses the ocean as ...
