Hybrid Harmonic Filter

Introduction

The equipment used to reduce the harmonics in the power system to an acceptable range is called hybrid harmonic filter. It is a device used to filter one or more harmonics in power system; Most of its structures are composed of inductance, capacitor, resistor and other components, that is, passive filter, which is also used for reactive power compensation; Emerging filtering technologies also include active filters.

Principle

The principle of electromagnetic induction and reactor is used for professional development. High performance filter capacitors are used in series with high linearity filter devices to form a filter compensation system to compensate reactive power while absorbing the main harmonic components in the system. The dynamic reactive power compensation and filtering functions are integrated, which can quickly follow the load changes. It has three main functions: restraining current fluctuations, absorbing grid harmonics and compensating reactive power.

Type

Generally, the hybrid harmonic filter is divided into different types according to the applied voltage, rated power, one or three phases and other different parameters depending on the load. But these are very effective filters that can protect expensive electrical equipment from excessive power caused by harmonics.

There are active and passive harmonic filters, and the main difference between them is the components used in the design of the filter. Active harmonic filters use active components, such as IC, BJT, IGBT and MOSFET, while passive harmonic filters use different passive components, such as resistors, capacitors and inductors.

Advantage

The advantages of harmonic filter include the following aspects:

1. Used to reduce harmonics in power system

2. Enhanced power flow

3. Provides the best results to keep the system safe

4. Provide energy efficiency to ensure the life safety of power system

5. Reduce power charges through harmonic control inside the power supply

6. Provides many advantages in a single system. Compared with the active filter, this harmonic filter is not expensive, and it provides the combined advantages of the two filters, such as active and passive

7. Reduced maintenance costs when connecting active filters

8. Filter is used to provide power factor development and harmonic correction

Application

Hybrid harmonic filter is used at important working circuit points to eliminate or reduce harmonic distortion and resonance. Generally, harmonic distortion may be caused by excessive incoming and outgoing current of equipment.

The filter can avoid a large number of harmonics generated by equipment damage, reduce operation and reduce operating costs. Therefore, they are used in HVAC, oil, gas, mining, wastewater and other different industries to avoid component damage or utility provider fines.
