To bring forth the issues related to power quality and to discuss the matter involving power engineers from industries, utilities as well as academia, the Power Engineering Chapter, Kolkata, jointly with the Industry Applications Chapter, Kolkata, organized the seminar on Power Quality (SPQ-2006) on 23rd December, 2006. The seminar was presided over by Prof. Ajit K Chattopadhyay, IEEE Fellow and Chair of IA Chapter. In his introductory lecture, Prof. Chattopadhyay stressed on the need to develop suitable equipment for improvement of power quality.
There were two invited talks in this seminar delivered by Prof. Sujit K Biswas of Jadavpur University and IEEE PES-DL Prof. Bhim Singh of IIT-Delhi. Dr. Kaushik Mukherjee, Treasurer, IA Chapter, introduced Prof. Sujit K Biswas and Prof. Sivaji Chakravorti, Chair, PE Chapter, introduced Prof. Bhim Singh.
Prof. Sujit K Biswas in his lucid presentation discussed the basics of power quality. Prof. Biswas gave stress on two areas, viz. power factor improvement and reduction of harmonics, and identified the equipment that are mainly affected by harmonics. Then Prof. Biswas presented some solutions to harmonics problems, viz. reactive power compensation using thyristor switched capacitors (TSC) and thyristor controlled reactors (TCR), harmonic traps and active power filters.
Prof. Bhim Singh in his detailed presentation talked on power quality improvement techniques. The talk of Prof. Singh was divided into two parts. In the first part, he discussed power quality improvement techniques using power filters. After discussing custom power devices such as DSTATCOM, DVR and UPQC, he dwelt at length on the use of passive, active as well as hybrid filters. Prof. Singh explained the usage of such filters for single-phase, three-phase three-wire and also for three-phase four-wire systems. In the second part of his talk, Prof. Bhim Singh highlighted the power quality standards in AC-DC converters and outlined the current distortion limits. Then he presented many different configurations of multipulse converters (both uni-directional and bi-directional) starting from six-pulse to thirtysix-pulse converters alongwith detailed comparative studies based on total harmonic distortion and magnetic parameters. Finally he spoke on the application potentials of such multi-pulse converters.
On behalf of the organizers, mementoes were presented to both the speakers as well as the session chairman. There were altogether 46 participants in this seminar.
