A New Approach to Object-Oriented Programming Language for Remote Power Quality Monitoring and Analysis Considering Harmonics
Use of micro processed technology enhances the power system operation and control tasks, but at the same time resulting into power quality problems for utility as well as consumers. One of the major issues of power quality is harmonics in power system. Through mandatory regulations, harmonics in the power system must be prevented to ensure good power quality. This paper presents a new approach of object-oriented programming for remote power quality monitoring and analysis with harmonic considerations. The real-time monitoring and analysis of power system parameters is inherently complex due to large data handling process. Object-oriented programming tool has been used as computational tool which performs monitoring and analysis in substation related to power quality, and gives subsequent analysis for the residual life assessment of substation equipment due to power quality. A GUI is created in java to create user-friendly environment. Data can be transmitted from remote stations to the central server and authority sharing has been developed as per the process. This is an innovative approach in electrical field in terms of substation monitoring which thereby improves power quality. A case study of distribution network supplying linear and nonlinear loads is presented which encompasses the effects of harmonics on substation equipments to find out the solution to be implemented.
