AI Technical Summary

Technical Problem

Existing multi-stage pumping station conveying systems are unable to adapt to rapidly changing working conditions when faced with time-varying parameters such as mud concentration and viscosity and complex fluid-structure interaction characteristics, resulting in problems such as overshoot, oscillation, and response lag. Furthermore, they lack a multi-pumping station collaborative optimization mechanism, leading to high energy consumption and low conveying efficiency.

Method used

By acquiring dredging capacity parameters in real time, dividing virtual slurry masses, and calculating the transport difficulty index based on density and viscosity values, combined with pump station response delay time and pipeline status, feedforward adjustment is achieved, and multi-level pump station collaborative control is optimized by utilizing collaborative compensation from adjacent pump stations.

Benefits of technology

It achieves highly stable and efficient control under complex time-varying conditions, reduces system energy consumption, improves mud conveying efficiency, and avoids the shortcomings of traditional control methods.

Abstract

The application relates to the field of slurry transportation, in particular to a multi-stage pump station cooperative control method, device and equipment based on dredging productivity, which comprises the following steps: acquiring the dredging productivity parameter at the outlet of the dredging pipe of a dredger in real time; dividing the slurry flow into multiple virtual slurry lumps based on a preset transportation volume and associating corresponding density values and viscosity values; calculating the transportation difficulty index of each virtual slurry lump based on the density values and the viscosity values; acquiring the current pipeline transportation state and calculating the time information of each virtual slurry lump to each pump station; calculating the adjustment time and the required adjustment amount of each pump station to each virtual slurry lump based on the time information and the transportation difficulty index; when the maximum adjustment amount of any pump station is less than the corresponding required adjustment amount, adjusting the insufficient adjustment amount based on the upstream and / or downstream pump stations adjacent to the pump station; at each adjustment time, controlling the corresponding pump station to carry out feedforward adjustment according to the required adjustment amount, which has the advantages that the method can adapt to complex time-varying working conditions and has the multi-pump station cooperation capability.
