A Typical Case Study of Voltage Boosting Solutions at the End of a Power Grid Line
In large orchards or farms, water supply is crucial.
Orchards are often located in remote areas such as mountainous regions, as shown in the diagram below:
Clearly, there are no suitable power lines nearby for irrigation. Considering pipeline layout, pump stations are often located near the orchard/farm but far from the power transformer.
As shown in the diagram below: Variable frequency intelligent control of the water pump has been implemented on-site.
In this project, the water pump is 2000km away from the transformer. The pump power is 30kW, the no-load voltage is 410V, and the cable is 35mm². During pump startup, the line voltage drop is large, leading to undervoltage shutdown.
After selecting a 150KVA wide-range low-voltage voltage stabilizer, the pump operates as shown in the diagram.

Pressure boosting effect during water pump startup
When the variable frequency intelligent water pump starts, the line voltage gradually decreases with the pump speed. The voltage stabilizer continuously increases the voltage to meet the pump’s operating needs. Once the pump starts at full power, we find that the input voltage is close to 260V. Due to the voltage stabilizer, the pump continues to operate normally.
The case study clearly demonstrates that the Voltage Stabilizer has a significant effect on boosting voltage at the end of a line and can completely solve the low voltage problem.
