Phd thesis on power quality

Jawaharlal Nehru Technological University, Anantapuram Completed Date: The past several years have seen a rapid increase powerr power electronics-based loads connected to low and medium voltage power distribution systems. These loads draw non-sinusoidal current from the mains, degrading the power quality by causing harmonic distortion.


Power. Quality. Pride.

This theorem phd thesis on power quality the equations for the current reference estimation in d-q co-ordinates thus leading to a more efficient and fast computation. This thesis proposes a three phase Shunt Hybrid Active Filter SHAF topology for harmonic reduction and power factor improvement in low and medium voltage power distribution systems. These loads draw powerr current from the mains, degrading the power quality by causing harmonic distortion. Continue reading proposed SHAF phr interconnects a three phase shunt active filter and tuned passive filters in parallel with the load. The compensation current reference for the proposed SHAF topology is obtained by using synchronous reference frame theorem. Fuzzy logic controller is adopted to maintain constant dc bus voltage at the dc buses of two level inverter and ACSLI.

For low voltage system 3-arm universal bridge voltage source inverter is used thssis active filter and in medium voltage system asymmetric cascaded seven level inverter ACSLI is used as voltage source inverter. The uniqueness of the proposed topology is the fact that it improves the harmonic filtering performance of a basic shunt tehsis power filter, as well as simultaneously improves the power factor by injecting reactive power at the point of common coupling PCC.

The compensation current reference for the proposed SHAF topology is obtained by using synchronous reference power theorem. This theorem simplifies the equations for the current reference estimation in d-q co-ordinates thus leading to a more efficient and fast computation. To generate the compensation current that follows the current reference, the hysteresis current control method is adopted for 2-level VSI in low voltage system and constant switching frequency subharmonic pulse width modulation CSFSHPWM is used for asymmetric cascaded seven level inverter ACSLI in medium voltage power distribution qualiyt.

For phd thesis on power quality voltage system 3-arm universal bridge voltage source inverter is used as active filter and in medium voltage system asymmetric cascaded seven level inverter ACSLI is used as voltage source inverter. To generate the compensation current that follows the current reference, the hysteresis current control method is adopted theeis 2-level VSI in low voltage system and constant switching frequency subharmonic pulse width modulation CSFSHPWM is used for asymmetric cascaded seven level inverter ACSLI in medium voltage power distribution system. These loads draw no current from the mains, degrading the power quality by causing harmonic distortion. The past several years have seen a rapid increase of power electronics-based loads connected to low and medium voltage power distribution systems.

    You are absolutely right. In it something is also to me it seems it is very excellent idea. Completely with you I will agree.

    In it something is. Earlier I thought differently, many thanks for the information.

    In my opinion you are not right. I am assured. I suggest it to discuss. Write to me in PM, we will talk.
