Research and synthesis of the automatic water level control system of the mine water tank according to the criterion of minimizing the dispersion of fluctuations of power consumption

Abstract

Practical value. The synthesis method is proposed for the system of automatic control of the water level in the mine reservoir based on the introduction of expert rules, thanks to which the variance of fluctuations in the total power of the pump engines is minimized. Reducing the variance of the change in power over time increases the predictability of the amount of energy consumed for pumping water, and also reduces the amount of time when a significantly increased total power of the pump drives is observed. This makes it possible to reduce specific energy costs for water pumping using the differentiated approach when calculating the cost of electricity.
