What is a steady-state model of a three-phase asynchronous motor?

In this paper, a new steady-state model of a three-phase asynchronous motor is proposed to be used in the studies of electrical power systems. The model allows for obtaining the response of the demand for active and reactive power as a function of voltage and frequency.

How asynchronous motors save energy?

The third is variable frequency speed regulation. The excess torque increases the consumption of active power and causes a waste of electric energy when the asynchronous motor is running at no load or light load, and it can run in a constant voltage state and save energy by reducing the rotational speed of the asynchronous motor [10, 11].

What is energy-saving control of asynchronous motors?

Energy-saving control of asynchronous motors by means of voltage regulation is essentially to regulate and control the terminal voltage of asynchronous motors. This paper adopts the strategy of motor current open-loop control and motor terminal voltage closed-loop control in order to reduce the complexity of the control system.

Can a three-phase IGBT inverter control an asynchronous motor?

In its use, asynchronous motors are widely used on an industrial scale. As time went by, asynchronous motor control itself also began to develop, starting from mechanically using switches to using inverters. The use of a three-phase IGBT inverter to control a three-phase asynchronous motor will be discussed in this research.

How to reduce reactive power absorbed by asynchronous motor?

The asynchronous motor, as an inductive load, needs to absorb reactive power from the power grid during operation. Therefore, installation of reactive power compensation equipment such as shunt capacitors can reduce the reactive power absorbed by the asynchronous motor from the power grid and transmitted by the line.
