UPQC power quality management device for distribution area

Introduction

As the power grid places increasing emphasis on line loss management, and users demand higher power quality in distribution areas, our company has developed a "Unified Power Quality Conditioner (UPQC) System" to address common power quality issues such as poor power quality and abnormal terminal voltage.

The device mainly consists of four parts: the UPQC master unit, UPQC slave unit, series transformer, and composite bypass switch module (thyristor and contactor). The UPQC master unit is connected in parallel with the grid, allowing it to sample current and compensate for reactive power, harmonics, and imbalances. Additionally, the UPQC master unit connects to the slave unit via a DC bus, providing stable voltage to the slave unit. The UPQC slave unit draws power from the DC bus, converts DC to AC through inversion, outputs AC voltage, and adjusts the voltage for the load via transformer conversion to achieve voltage regulation.

Product Advantages

The "Unified Power Quality Conditioner (UPQC) System" developed by our company boasts numerous outstanding features.

First, it excels in functionality and performance. It comprehensively and effectively addresses a range of power quality issues in distribution areas, such as overvoltage or undervoltage, three-phase imbalance, low power factor, and excessive harmonic content, delivering significant results in resolving these problems.

Second, the system offers diverse application scenarios and strong adaptability to both the grid and loads. Whether it's distributed renewable energy integration, electric vehicle charging stations, seasonal or intermittent loads, or distribution areas with high power quality requirements, it seamlessly adapts and performs effectively.

Third, the installation of the "Unified Power Quality Conditioner (UPQC) System" is simple and flexible, while maintenance and repair are safe and convenient, providing great ease for subsequent operations.

Function Introduction

The UPQC Unified Power Quality Conditioner is primarily used to address various power quality issues in distribution areas, such as overvoltage or undervoltage at the end of distribution transformers or lines, three-phase voltage and current imbalance, low power factor, and high harmonic content. It is a powerful, high-performance, and cost-effective comprehensive power quality management product for distribution systems.

Complete Cabinet Introduction

Our company's comprehensive power quality management equipment mainly consists of the following components:

The entire system is an advanced comprehensive power quality management device designed to simultaneously address voltage and current-side power quality issues in power systems. The UPQC combines the functions of series active power filters and shunt active power filters. By real-time detection and analysis of grid voltage and load current, it generates appropriate compensation voltage or current to eliminate grid voltage fluctuations, harmonics, reactive power, three-phase imbalances, and improve power factor.
