“…Determining how to further simplify the calculation process is the subject of this study. On the basis of the abovementioned studies, according to the induction motor Г-type equivalent circuit [42], the stator copper loss will be regarded as an invariable loss associated with the stator voltage, and the stator iron loss will be regarded as an invariable loss associated with the stator voltage (this is different from previous studies [37][38][39][40][41] and is the innovation of this work). The rotor copper loss will be regarded as a variable loss that changes according to the variable load.…”

“…The paper [38] directly solved the optimal voltage based on the specific slip. The paper [39] and [40] studied the voltage regulation and energy savings of motors with periodic load changes. For the paper [41], the electromagnetic power of the motor is used to calculate the optimal operating voltage value, but it is difficult to measure the electromagnetic power in actual operation.…”

“…(6)(7) in Reference 1 are contradictory to a certain extent by using the stator voltage of the motor during operation to calculate the optimal stator voltage of the motor. Essentially, the principle of establishing the objective function of the electrical total loss [37][38][39][40][41] is to decompose the total electrical loss into the invariable loss only related to the stator voltage (the stator copper consumption) and the variable loss only related to the load of the motor (the rotor copper consumption). In fact, when the motor drives a constant-torque load, if the principle above is applied to establish the objective function of the total electrical loss and determine the optimal voltage, the calculation process cannot be simplified.…”

To achieve optimal voltage regulation and energy savings of an AC induction motor operating under constanttorque and variable-working-load conditions, and consider a motor's T-type and Γ-type equivalent circuit, the copper and iron losses of the stator were regarded as invariable losses that were only related to the stator voltage, and the copper losses of the rotor were regarded as variable losses that varied with the load torque. The total electrical loss formula and the optimal voltage regulation formula for the motor were deduced. The formulas revealed that the total electrical loss of the motor was affected by the stator voltage and the rotor load torque, and the optimal voltage regulation changed exponentially with the load torque of the motor. The calculation results of an engineering example showed that when s = 0.01-0.03 and the motor operated stably, the motor load torque error was not more than 1.8 Nꞏm based on the exact and approximate solutions of the slip s. The total electrical loss showed almost no calculation error when the working voltage of the motor was higher than 230 V. The optimal voltage regulation and its error increased with the increase in the motor load torque, but within the working voltage range of the motor, the optimal voltage regulation error did not exceed 6 V. The total electrical loss with the optimal voltage regulation mode and a variable load torque was less than the total electrical loss of a 380-or 220-V constant driving mode. With the increase in the load rate, the total electrical loss increased. When the motor's load did not exceed the medium load and the motor operated with optimal voltage regulation, the energy-saving effect was significant. In particular, when the motor operated without a load, the total electrical loss was almost 0.

“…Feng et al [7] accurately built a mathematical model of a load motor based on dynamic changes in the pumping load; they realized that the system power matching could improve the motor's efficiency. An energy analyzing model and 3-D dynamic model were also constructed [8,9]. Nevertheless, structural optimization can only reduce the energy loss of the drive motor, and will not solve the problem in principle.…”

Many oil fields are full of wind energy. At present, wind power generation technology has catered to oil fields. A larger wind turbine is used to supply power to several pumping units. As a result of the structural characteristics of the pumping unit, the efficiency of the electromotor is very low, which leads to a reduction in the utilization rate of wind energy. At the same time, considering the high cost of large wind turbines, the energy saving effect is not obvious in practical applications. This paper proposes an energy supply model of a pumping unit driven by a small wind turbine and a new wind-motor hybrid structure. Instead of wind power generation technology, wind energy drives the pumping unit directly via a mechanical–hydraulic transmission system. This new mechanical-hydraulic system can optimize the power confluence of wind and electric power. To enhance the efficiency of the motor, a mathematical model and a test station were established. The correctness of the energy conservation method and the mathematical model was verified, and the performance of the wind-motor system was studied.

The environmental and economic pressures caused by energy consumption have led to an increased consciousness of energy-saving in the manufacturing industry. To this end, this paper focuses on an unrelated parallel machine problem with multiple auxiliary resources, which is a typical configuration in the lithography process of wafer fabrication. By comprehensively considering the jobs with different processing demands, setup times, ready times, resource constraints and energy consumptions, a scheduling model with the objective functions of minimizing the total energy consumption of the system and the total weighted completion time is developed. Based on the mathematical model, a novel modified multi-objective artificial immune algorithm integrated with the non-domination sorting strategy is proposed to solve the problem. Furthermore, to improve the performance of the proposed algorithm, clone operators, neighborhood search operators, and elite preservation operators are applied to the algorithm. The experimental results and analysis validate that the presented algorithm is efficient and effective.
