The article considers synthesis of an expert system for controlling electric power consumption by pumps of main water drainage facilities of an underground mine on the basis of the Mamdani fuzzy inference algorithm. The proposed system has a MISO-structure (multiple-input, single-output) with two input variables, such as water inflow and power cost as well as one output coordinate – power of pumping units. Two bases of fuzzy rules such as conjunction (AND) and disjunction (OR) are formed. By simulation modelling, a comparative analysis of fuzzy control systems for power consumption by water drainage facilities is carried out, as well as a system without control, when the pump performance is stabilized, during week and month periods. It is established that OR-rule based systems can reduce power costs by 1.89% during a week and by 2.28% during a month, and AND-rule based systems by 4.13%, as well as by 5.43% during week and month, respectively. At the same time, we note that the economic effect is achieved not through a decrease in power consumption, but by adjusting the operation mode of the water drainage facility, which involves ensuring maximum efficiency of groundwater drainage when the power cost is high, and minimum efficiency when it is low.

“…where, η drive -efficiency of the pump motor drive; ρfluid density; gacceleration due to gravity Unlike [17] where the drive losses were obtained from the manufacturer's documentation basing on the current torque readings, in this study all the possible drive efficiencies are preliminary estimated from the vector-controlled motor drive and stored in the lookup table before pumping to predict the future system efficiency at the required head inputs. Experimentation was done using a laboratory setup shown in Fig.…”

“…Some methods appeared for the real-time motor drive efficiency estimation. One of them, proposed in [17], addressed the drive manufacturers' documentation where the motor and power converter losses are collected for their part-torque operation at different speeds. It covers the necessity in accurate torque measurement and manufacturer's data extrapolation.…”

The growing energy market and increasing energy costs require new solutions in pumping technology aiming to rise the energy efficiency. In the study, a novel centrifugal pump predictive control organisation is proposed. Unlike the traditional speed-oriented pump regulation, an efficiency-oriented approach is realised where the specific power loss in the motor drives are taken into account alongside the general pump and pipeline losses. The offered management strategy and algorithm are based on the prediction of optimal operating points using combined tabulated and analytical performance characteristics of a pumping station. Applying the efficiency distribution diagram, the control map has been designed intended for running the optimal number of pumps at the appropriate speeds. As a result, the system performance within one of the best efficiency regions is maintained now at all the requested head and pressure inputs and pipeline condition instabilities.

<p class="Normal1">In this paper, a Matlab based GUI and Propotinal Integral Dervative (PID) controller is designed to automatically regulate the flow-rate of the circulating fluid. When fluids are transported over long distances, the pressure and flow rate have to be monitored remotely in a control room. Using an HMI or Control Panels the flow rate can be increased or decreased to compensate for pressure drops or disturbances. This paper attempts to demonstrate such an Industrial Control Operation in a scaled-down environment. A Graphical User Interface or GUI is constructed which enables the Operator to monitor, as well as control an electronically actuated Control Valve which can efficiently regulate the flow-rate. Automatic operations have also been implemented using a PID controller algorithm, which tries to track the Set-point in Real-time.</p>
