Segmented drainage control method for drainage pump station water storage bin

Abstract

The invention discloses a segmented drainage control method for a drainage pump station. The method comprises the following steps that h<real-time>, H and H<lower limit> of a water storage bin, a water inflow calculation time period t<water inflow>, a water level h at the initial moment of t<water inflow>, a water level h<ending water inflow> at the ending moment of t<water inflow> and water discharge Q<drainage> in the t<water inflow> time period are acquired; according to the mapping relation of Q<drainage>, t<water inflow>, h, h<ending water inflow> and the water level-water storage capacity, the water inflow rate q<t water inflow> of the water storage bin is determined; the variable flow delta q<t drainage> in each drainage time period is determined; a theoretical operation number X<theory> of a drainage pump is determined according to q<t water inflow> and delta q<t drainage>; the water level H<ending drainage> of the water storage bin at the drainage ending moment in each drainage time period is determined; X<theory> is adjusted according to the relation between h<real-time> and H<ending drainage> and H or H<lower start and stop>, and the actual operation number X<actual> ofthe drainage pump is determined; and according to the scheme, segmented drainage of the drainage pump station is more economical.

Description

technical field

[0001] The present application relates to the technical field of mine automation control, in particular to a segmented drainage control method for a water storage bin of a drainage pumping station. Background technique

[0002] With the continuous development and investment of mine automation control technology, most underground mining mines have realized the automatic control of drainage pumping stations. The centralized control of the pumping station and the water level control automatic drainage system achieve the goal of reducing manpower and increasing efficiency, but it is not economical because the electricity used by the drainage pump varies according to the time of day. A tiered electricity price is set during the normal period, the electricity price is high during the peak period of electricity consumption, and the electricity price is low during the valley period of electricity consumption. Therefore, if the drainage pumping station only considers...
