The paper proposes the application of constant frequency unified power quality conditioner to overcome the power quality issues in fixed speed wind mill connected with the micro grid. The power circuit of a constant frequency unified power quality conditioner (CF-UPQC) is based on a combination of UPQC, and frequency regulator (matrix converter). This equipment incorporates compensation functions...
Power Quality issues are becoming a major concern of today's power system engineers. Harmonics play significant roll in deteriorating power quality, called harmonic distortion. Harmonic distortion in electric distribution system is increasingly growing due to the widespread use of nonlinear loads. Large considerations of these loads have the potential to raise harmonic voltage and currents in an electrical...
Energy efficiency means the efficient energy usage that is using less energy to provide the same service. Due to the penetration of advanced electronics in industrial and commercial applications many utility net works fall into the problem of inefficient operations. Though the advanced technologies are used to improve the productivity and improving the facility of the consumers, they will cause severe...
Wind energy is one of the fastest-growing sources of electricity in India and around the world. In spite of being cheap, clean and abundant the continuous fluctuations in the renewable energy causes significant power quality issues. This paper presents a technical review of power quality problems associated with grid connected wind power plant and describes the Dynamic Voltage Restorer that injects...
Power quality is becoming a major concern of today's power system engineers. Harmonics play an important and major roll in deteriorating power quality, called harmonic distortion. Harmonic distortion is measured in terms of THD (Total Harmonic Distortion). This paper presents harmonic field measurement for domestic loads in power distribution network. The specific case study has been conducted at...
Voltage sags and swell are common in our supply systems. Adjustable Speed Drives are susceptible to voltage sags occurring due to faults in electric power systems. There are different techniques to enhance ride through capability of ASD's during voltage sag and swell conditions. These are aimed at maintaining the DC-link voltage constant by injecting energy from an external source. The Buck-Boost...
Power quality is becoming a more concern of today's power system engineer due to the rapid growth of non-linear loads, such as power electronic control equipments and electric arc furnace (EAF). Harmonics and voltage flicker are the power quality problems which are introduced to the power system as result of non-linear behavior of the electric arc furnace operation. Electric arc furnace model is needed...
