Dynamics of flooding of submersible pump stations and identification models for their automatic protection

Deep-seated pumping stations, under conditions of improper operation, are constantly flooded by groundwater and leaks from pumping units. Therefore, this work focuses on solutions that allow overcoming this production problem by studying the dynamic processes of water accumulation and structural identification of an automatic control system for removing these excesses. Overcoming these flooding processes in the machine hall is achieved by equipping special accumulators and pumping out the excess water that collects in them using a special pump and an automatic control system. The article presents the results of experimental work based on structural identification methods in the MatLab environment. This allowed us to recommend a system for regulating the pumping of excess water based on a PID controller with parameters tied to the production collection tank. Specifically: hmax = 2 m is the maximum water level (overflow level); hon = 1.8 m is the pump on level; hoff = 0.2 m is the pump off level; Qp = 40 L/min is the maximum pump capacity.
