Harmonics filter design software

Harmonic filters are composed of series or parallel inductorcapacitor branches tuned to specific frequencies to provide a low impedance path to the harmonic components. With the harmonic analysis module, you can simulate harmonic current and voltage sources, identify harmonic problems, reduce nuisance trips, design and test filters, and report harmonic voltage and current distortion limit violations. They are grouped into performance and rating criteria. The former relate to normal expected operating conditions. Steciuk of northeast power systems inc, dives into key concepts in the design, construction, application and modeling of mediumvoltage 2. For the reduction of the harmonics, you need a rugate filter design, or quasirugate with refractive index steps. The tuning depends on the configuration of the filter designed. Installing a passive shunt harmonic filter near harmonic producing loads is one of the common methods of mitigating harmonic distortion. A properly designed harmonic filter can prevent the harmonic current from injecting into the system, or it can provide a low impedance path at the tuned frequency to remove a parallel resonance. Harmonic filter design considerations by ieee 1531 power. Design of harmonic filters for renewable energy applications.

When developed the programme will consist of many different files dealing with the coding for gui nd calculations individually but. Design of harmonic filters for renewable energy applications abstract harmonics are created by nonlinear devices connected to the power system. Show chart for design and analysis of harmonic filters using matlab. The harmonic filter editor provides all the practical and popular filter structures for you to choose from.

Simulation and experimental results for ga based design are presented. The instructions for use of the software can be found in the document manual. Introduction nowadays, the most common practice for harmonic mitigation is the installation of passive harmonic filters. As a result, power authorities usually require harmonics to be kept to a minimum typically designed harmonic filter can prevent the harmonic current from injecting into the system, or it can provide a low impedance path at the tuned frequency to remove a parallel resonance.

Power system harmonics are multiples of the fundamental power system frequency and these harmonic frequencies can create distorted voltages and currents. Meanwhile, the rating criteria refer to unusual conditions that may place a more severe duty on the equipment. The purpose of the harmonic filter is to shunt some of the harmonic current from the load into the filter to reduce the amount that goes to the electrical power system. Ieee 1531 has outlined key harmonic filter design considerations for its proper selection. Tci is the leading manufacturer of active filters and passive filters to mitigate harmonics and improve power quality. The harmonic analysis is made on orders 3, 5, 7, 11, 17, 19, 23, 25 exclusively. The kaiser apodization window is used as an envelop function around the rugate. The leading source for active and passive harmonic filters. Filters, optimization, power system harmonics, power quality, total harmonic distortion.
