This paper proposes a matrix converter based unified power quality conditioner (MC–UPQC) for mitigating power quality problems. This proposed system is a combination of unified power quality conditioner and matrix converter. The UPQC is a combination of back-toback connected series and shunt active filters through a dclink. Voltage disturbances and harmonics are compensated by series active fil...

This paper proposes a photovoltaic (PV) and battery interfaced series hybrid active power filter (SHAPF), which consists of series active power filter and an LC shunt passive filter. The main benefits of the proposed system provide the compensation against the voltage harmonics, current harmonics and voltage interruption for the whole day. A series active power filter (SAPF) demands a source of...

ISSN: 2319-1112 /V3N1: 36-46 ©IJAEEE Abstract—Application with renewable energy sources such as solar cell array, wind turbines and diesel generator have increased significantly during the past decade. To obtain the clean energy, the hybrid solar–wind power generation is used. Consumers prefer quality of power from suppliers. The quality of power can be measured by using parameters such as volt...

The impact of wind turbines and photovoltaic systems on network operation and power quality (harmonics, and voltage fluctuations) is very important. The capability of the power system to absorb this perturbation is dependent on the fault level at the point of common coupling. The paper deals with power quality case studies conducted on existing renewable resources-based systems. Voltage fluctua...

A full compensating system for distribution networks which is able to eliminate harmonics, correct unbalanced loads and generate or absorb reactive power is presented. The system is based on a combination of a Thyristor Binary Compensator (TBC), and a PWM-IGBT Active Power Filter (APF) connected in cascade. The TBC compensates the fundamental reactive power and balances the load connected to th...

this paper presents an innovative active power filter design method to simultaneously compensate the current harmonics and reactive power of a nonlinear load. the power filter integrates a passive power filter which is a rl low-pass filter placed in series with the load, and an active power filter which comprises an rl in series with an igbt based voltage source converter. the filter is assumed...

The power quality issues are of great concern now a days. The increasing use of power electronic devices based nonlinear loads deteriorate the quality of power. Power electronic appliances are widely used in industrial, commercial and utility system thus leading to various power quality problems. This leads to harmonics being injected into the distribution system and also reactive power burden....

Magnetic core saturation of transformers and rotating machines generate harmonics. Harmonics are integer multiples of the fundamental frequency. Harmonics is caused by nonlinear devices in the power system. Due to the non-linear loads, power frequency harmonics exist mainly in distribution systems. The current harmonics cause voltage harmonics, hence resulting in nonsinusoidal supply voltage in...
