Induction motors can cause problems with the electrical quality of other devices voltage drop due to the high starting current when starting, so the reactor starting method is often used when the capacity is large. Since this induction motor consists of resistance and reactance components, the power factor is relatively low. When an induction motor starts, the reactive power is greater than the active power, so the power factor is low. As the speed increases, the sizes of the active and reactive power are reversed, and the power factor improves. In reality, the power factor when driving at rated speed is lower than that required by the power company, so the power factor is compensated with the help of a reactive power compensation device such as a capacitor. In the reactor starting method, capacitors are sometimes installed at the front and rear ends of the reactor. Reactor startup requires a long startup time and a long operating section with a low power factor, and the power characteristics appear different during startup depending on their installation location.
In this study, we analyzed how changes in current and power affect the power factor during startup at the installation location of the capacitor in the reactor startup method.
