Embodiment approach
[0037] (1) The flow change process of the unsteady flow is recorded in the data file corresponding to the time flow, and the control terminal constantly sends the flow corresponding to the time to the frequency conversion module according to the time in the data file, and the frequency conversion module continuously uses the time The corresponding flow rate is converted into the frequency of the pump motor and sent to the frequency converter, and the frequency converter continuously controls the motor frequency of the water pump according to the frequency of the water pump motor sent by the frequency conversion module, so that the water pump will strictly follow the flow change of the unsteady flow compiled in the data file The process transports water from an underground reservoir to the model forebay.
[0038] (2) When the difference between the real-time flow fed back by the electromagnetic flowmeter and the flow corresponding to the time in the data file exceeds 1L / s, the c...
Embodiment 1
[0051] The unsteady flow control system of the downstream model test of the hydropower station provided by the present invention is applied to the unsteady flow control of the downstream physical model of the Xiluodu Hydropower Station. Through application, it is found that the operation of the system is simple and clear, and it can strictly follow the data corresponding to the flow at a given time The file automatically controls the complete unsteady flow change process of the discharge of the power station under each working condition and combined working conditions, the control accuracy reaches 99%, and the overshoot is within 10L / s.
[0052] In summary, the embodiment of the present invention not only has fast response speed and high control precision, but also can accurately simulate and fully automatically control the unsteady flow process of power station discharge.
