A medium-power current source converter (CSC)-based shunt active power filter (APF) system is designed and implemented to suppress the amplification of low-order harmonics at the medium-voltage (MV) interface bus between the distribution and transmission systems, owing to the presence of large shunt capacitor banks installed only for reactive power compensation. Four CSC-based APF modules designed at 1.0 kV are operated in parallel and connected to the 31.5-kV MV bus via a specially designed coupling transformer. In each APF module, a specially designed LC-type input filter eliminates the switching ripples, and active damping method embedded into the control software suppresses harmonic frequencies around the corner frequency of the input filter. The resulting system can operate at relatively high frequencies in the range from 2.0 to 3.0 kHz, depending upon which selected harmonics among 5th, 7th, 11th, and 13th are to be eliminated. Furthermore, in order to reduce the installed capacity of CSCs, selective harmonic amplification method is applied to the APF system described in the paper. MV APF system has been built as a mobile system for temporary connection to a problematic MV interface bus until a permanent solution is found for that location in the distribution system.

A Selective Harmonic Amplification Method for Reduction of kVA Rating of Current Source Converters in Shunt Active Power Filters Terciyanli, Alper; Ermiş, Muammer; Cadirci, Isik (2011-01-01) This paper describes a new approach to the design of current-source converter (CSC)-based shunt active power filters (APFs) to reduce the converter kilovolt-ampere rating considerably. This design approach is called the selective harmonic amplification method (SHAM), and is based on the amplification of some selected harmonic current components of CSC by the ac-side filter, and the CSC control system specifically designed for this purpose. The proposed SHAM has been implemented on a CSC-based APF for the el...
High Performance Harmonic Isolation By Means of The Single-phase Series Active Filter Employing The Waveform Reconstruction Method Senturk, Osman S.; Hava, Ahmet Masum (2009-09-24) This paper proposes the Waveform Reconstruction Method (WRM), which is utilized in the single-phase Series Active Filter's (SAF's) control algorithm, in order to extract the load harmonic voltage component of voltage harmonic type single-phase diode rectifier loads. Employing WRM and the line current sampling delay reduction method (SDRM), a single-phase SAF compensated system provides higher harmonic isolation performance and higher stability margins compared to the system using conventional synchronous re...
A unity-power-factor buck-type PWM rectifier for medium/high-power DC motor drive applications Bilgin, HF; Kose, KN; Zenginobuz, G; Ermiş, Muammer; Nalcaci, E; Cadirci, I; Kose, H (2002-09-01) This paper describes the application of a single-stage unity-power-factor buck-type pulsewidth modulation (PWM) rectifier to medium- and high-power variable-speed dc motor drives. The advantages of the developed system are low harmonic distortion in ac supply currents (complying with IEEE Std. 519 and IEC 555), nearly unity power factor over a wide operating shaft speed range, and nearly level armature current and voltage waveforms. These properties of output voltage and current quantities of the converter ...
High Performance Harmonic Isolation and Load Voltage Regulation of the Three-Phase Series Active Filter Utilizing the Waveform Reconstruction Method Sentuerk, Osman S.; Hava, Ahmet Masum (2008-10-09) This paper develops the Waveform Reconstruction Method (WRM) for high accuracy and bandwidth signal decomposition of voltage harmonic type (V-type) three-phase diode rectifier load voltage into its harmonic and fundamental components, which are utilized in the Series Active Filter (SAF) control algorithms. The SAF compensated system utilizing WRM provides high performance load harmonic voltage isolation and load voltage regulation at steady-state and during transients compared to the system utilizing the sy...

The VSC STATCOM is composed of a +/- 750 kVAr full-bridge VSC employing selective harmonic elimination technique, a low-pass input filter, and a /Y connected coupling transformer for connection to medium voltage bus. The power stage of VSC based STATCOM is composed of water-co...
