How to Optimize the Layout of Cylindrical Type Split-Phase Compensation Capacitors for Decentralized Single-Phase Loads in Agricultural Irrigation Systems?

In the vast agricultural areas, the power network of the irrigation system is so complex that it resembles a network of intertwined capillaries. Its load characteristics are completely different from those of industrial factories. The decentralized arrangement of pump motors in agricultural irrigation systems, the widespread use of single-phase equipment, and the significant seasonal load fluctuations often make traditional centralized reactive power compensation schemes ineffective. Therefore, optimizing the layout of cylindrical type split-phase compensation capacitors to meet the specific requirements of the agricultural irrigation system has become a key issue for improving the power quality of the grid in the agricultural irrigation system.

Dual-Track Strategy of Local Compensation and Centralized Regional Compensation

The primary characteristic of agricultural irrigation systems is their dispersed load; The primary characteristic of agricultural irrigation systems is load dispersion; the power of individual pumps is relatively small but the distribution is extensive. To address this issue, the optimal reactive power compensation strategy should adopt a dual-track approach, combining local compensation and regional centralized compensation. For deep well pumps with a power exceeding 5 kilowatts, it is recommended to directly install small-capacity split-phase compensation capacitors beside the motor control box to achieve local compensation for each pump. For irrigation areas consisting of dozens of small pumps, regional compensation points should be set on the low-voltage side of the distribution transformer, and cylindrical type split-phase compensation capacitors should be configured according to the actual load conditions of each phase. This layered layout avoids the high cost of individually configuring each reactive power compensation device while ensuring effective reduction of reactive current in remote lines.

Intelligent Coordination of Phase Sequence Identification and Dynamic Switching

Another significant characteristic of agricultural irrigation systems is the extreme imbalance of three-phase loads. Since the start-up and shutdown times of water pumps depend on agricultural needs, the load on phase A might reach as high as 30 amps at a certain time, while phase B might only have 5 amps. This necessitates that the split-phase compensation capacitors should possess precise phase sequence identification capabilities. The three independent compensation units of the cylindrical split-phase compensation capacitors monitor the reactive power demand of their respective phases. By acquiring the voltage and current data of each phase in real time through an intelligent reactive power compensation controller, the entire low-voltage reactive power compensation system can accurately determine which phase requires how much compensation, ensuring that even under severe three-phase imbalance conditions, the power factor of each phase can be synchronously improved to above 0.95.
