“…This system consists of several banks of supercapacitors connected to the DC link of the frequency converter. In this work, the simulation model of a buffer power supply based on supercapacitors has been improved compared to previous versions of the model by adding the possibility to recharge the supercapacitor blocks by connecting them through a bidirectional DC-DC converter-Figure 2 [2]. The flow of energy from or to the buffer must be controlled according to the power management requirements.…”

“…Despite the wide range of the listed methods for starting an electric drive in remote areas, each of them comes with several disadvantages. Most of these disadvantages, such as inefficiency, pollution, and dependence on other raw materials, have been considered in previous works, but now it is proposed to consider the disadvantages of using rechargeable batteries as a stand-alone sources [2].…”

In the paper, a model of a three-phase frequency-controlled induction electric drive has been developed in Simulink Matlab 2019 (MathWorks, Natick, MA, USA). This model is mathematically converted into a two-phase model by transforming equations. It is proposed to compensate the voltage drop in the power system during start-up operation under load by using supercapacitors as a buffer power source. A block of supercapacitors was calculated. Simulation modeling was performed at a different voltage than the network. The diagrams of the transient processes occurring in the electric drive when the power supply is changed were prepared. It was found that such a principle of implementing an additional source of electric energy allows to start induction electric drives in areas remote from industrial networks without significantly affecting their static and dynamic characteristics.
