Induction motors are widely used as a power source for rotating loads due to their simplicity of structure, robustness, long lifespan, and ease of maintenance. However, these motors can cause voltage drops in loads connected to the same line when a significant voltage drop occurs during the starting process, as high current is generated. To mitigate this issue, various starting methods are employed based on the motor’s capacity to reduce the starting current.
In drainage facilities that are operated temporarily during the rainy season, low-head pumping facilities are typically used. For such drainage pumping stations, which require the instantaneous discharge of large volumes of water, high-capacity multi-pole induction motors are often employed. When the motor capacity is large, reactor starting is frequently chosen over direct starting. Additionally, it is essential to consider the duration of the voltage drop when selecting the starting method. In drainage facilities, the facility capacity may be large due to temporary operations, but the operating system is relatively simple.
This study compared and analyzed changes in voltage and the time required to reach the rated speed when pumping equipment, considering the moment of inertia, was started directly using a multi-pole induction motor and when started with a reactor. The analysis confirmed a difference in response time, and the voltage drop was found to be within the allowable range.
