Acrel APF Series Active Power Filter Three Phase 380V Reduce Harmonic Current Drawer Type

Video Introduction

Active Power Filter (APF) is connected in parallel with the loads. A current generator (power unit) that converts the control signals generated by the filter controller into the filter compensation current. A filter controller that determines the anti-harmonic current to be injected based on the line current measurements and the user's requirements. The line current measurements are obtained from current transformers (CTs). The user enters his requirements by means of the user interface.

Frequently Asked Questions

Q1 How does the Active Power Filter (APF) work in a power system?

The APF is connected in parallel with the loads. A built-in current generator converts control signals generated by the filter controller into filter compensation currents. Based on real-time line current measurements obtained from current transformers (CTs), the controller injects anti-harmonic currents to filter out system harmonics according to user requirements.

Q2 What kinds of harmonic compensation capabilities does this APF offer?

It features a highly flexible compensation method. It can compensate for harmonics only, reactive power only, or both harmonics and reactive power simultaneously. It covers the 2nd to 50th harmonics, and specific harmonics can be selected for targeted compensation.

Q3 What are the main technical benefits of this APF system?

Key benefits include linear compensation with a fast response time of ≤ 5ms, the ability to manage three-phase power imbalances, high reliability through imported IGBT components, and a DSP digital control system for fast, real-time calculation and detection.

Q4 What capacity modules are available and what is the system efficiency?

Modules are designed using a standard modular structure to ensure high reliability. The available module capacities are 30A, 50A, 75A, and 100A. The overall operating efficiency of the system is ≥97.5% with active losses kept ≤2.5%.

Q5 What protection functions and remote communication capabilities are built-in?

The system comes with over 20 types of built-in protections, including over-voltage, under-voltage, overheating, over-current, and short circuit protection. It also features RS485 and Ethernet interfaces, enabling remote communication and real-time system monitoring through a PC.
