overview

Among the three load imbalances, the price adjustment device is mainly used for low-voltage distribution users to control three-phase current imbalance, low phase voltage and complementary reactive power, and optimize power quality

The YC-SPC series product specifications cover 50A/35Kvar. 75A/35Kvar 150/100Kvar. It can simultaneously compensate for three-phase unbalanced current and reactive power, achieve connection, and dynamically compensate.

The YC-SPC series can comprehensively improve the power quality in the substation area. Specifically, as follows.

Solve the problem of three-phase imbalance in the distribution network and reduce line losses

Stabilize three-phase voltage, improve power supply quality, and enhance the electrical environment

Solve the problem of single-phase overload in transformers and improve their operating life

Reactive power balance. Improve the effective output capacity of the distribution network

At present, there is a serious three-phase imbalance phenomenon in rural and urban power grids across the country. Shaanxi, Zhejiang, Hebei, Gansu, Sichuan and other places have implemented three-phase imbalance, reactive power compensation, and low-voltage transformation projects. Xi'an Yachuan Electric Power Technology Co., Ltd. has also contributed to the governance of three-phase imbalance in these areas.

system function

Based on the actual situation on site, the technical personnel proposed a plan to install a three-phase unbalance adjustment device SPC on the transformer side. The three-phase unbalance regulating device SPC can control the three-phase current unbalance. Think about low and reactive power compensation, optimize power quality

Governance benefits

Direct benefits

Micro bottom solves the problem of uneven three-phase distribution network and reduces line losses of low-voltage distribution transformers and above power grids.

Using reactive power to achieve on-site balance, improving the processing and equipment utilization of distribution transformers

Real time improvement of voltage quality, stabilization of system voltage, enhancement of distribution quality, and improvement of electrical environment.

Resolve the issues of transformer operation caused by three-phase imbalance and extend the lifespan of the transformer substation

Indirect benefits

Improve the power quality of low-voltage distribution networks in the region and greatly reduce the imbalance of outgoing current in distribution transformers

Reducing the faults and accidents caused by negative and zero sequence currents due to unbalanced three-phase loads in the distribution network has improved the safety and reliability of the distribution system

Reducing the negative and zero sequence currents generated by the imbalance of three loads in the distribution network has extended the service life of distribution transformers, relay protection devices, and power equipment
