Power quality refers to the provision of the clean and stable electrical power supplies with least interruptions of current and voltage However, power quality problems arise due to the application of nonlinear loads with end user devices. Electrical installations majorly suffer from adverse effects of harmonic currents and voltages. Though, this problem has been decades long and pattern of investigation for the researchers but due to evolution of semiconductor technology, it has become burning issue with reference to the power system loads. Therefore, it becomes necessary to mitigate these harmonics for the safe operation of electrical appliances. Thus, harmonic passive filters are cost effective and easy to implement. In this work, the mitigation of current harmonics has been accomplished through single tuned Shunt Harmonic Passive Filter (SHPF). Furthermore, the application of six pulse multiplication converter technique ensures the mitigation of dominant 3rd harmonic currents and reduction of succeeding 5th and 7th harmonic currents. Furthermore, shunt operation of single tuned harmonic passive filter enables the current to follow the low impedance path. Consequently, the current harmonic distortion becomes less than 5 % according to allowable IEEE 519 -1992 standards. This reduction in harmonic distortion not only reduces the losses incurred in the system but it also improves the energy efficiency of the electrical Power Distribution System (PDS).Keywords

Objectives: For the efficient and reliable operation, substation IEDs status must be monitored consistently and event information must be disseminated timely between substation levels. Methods/Statistical Analysis: Traditional power grid substations are facing infrastructural, operational, automation, systematic, monitoring and control issues. The smart grid concept and advancement in instrumentation and automation has open up the potential of substation automation system through which substation automation, intelligence and control is achieved, but devices interfacing, interoperability, time critical information exchange, substation devices status monitoring and data dissemination type issues are still in research phase. Findings: In this research work, substation bay level IEDs time critical data information dissemination model is designed by IEC 61850 standard using publisher subscriber communication. Based on IEC 61850 substation devices data object and interfacing models, a novel substation communication service mapping is proposed for the time critical data information dissemination. The proposed communication service mapping is based on abstract service communication interface technique by which an object oriented data and object models and communication service is directly mapped at Ethernet data link layer. Application/Improvements: To disseminate the data message using the proposed communication service an IEEE 802 based Ethernet frame structure is designed and configured using abstract syntax notation one technique.Keywords
