A unified software approach is the most cost-effective and efficient solution in resolving PQ problems. A customized power electronics system analysis program provides the engineer with a fast and sufficiently accurate tool in making the recommendation. The paper describes a program that constitutes a module of a PQ workstation. Graphic input and output interfaces and capability of developing libraries are some of the highlights of the implementation

Computerized classification and characterization of the data will help in dealing with voluminous quantities of monitored data. An artificial neural network (ANN) approach with and without a fuzzy system for classifying the disturbances in a power system is developed and tested. The results obtained demonstrate the power of neural networks in classifying the commonly encountered disturbances of sags, swells, waveform distortions, interruptions and impulses and the effect of the fuzzy system on the network

The power quality problems become apparent when the user's equipment or systems maloperate or fail. Since power quality concerns arise from a wide variety of sources and the problem fixes are better achieved from the expertise of field engineers, development of an expert system for power quality advisement seems to be a very attractive and cost-effective solution for utility applications. An expert system thus developed gives an understanding of the adverse effects of power quality related problems on the system and could help in finding remedial solutions. The paper reports the design of a power quality advisement expert system being developed using CLIPS 6.0. A brief outline of the power quality concerns is first presented. A description of the knowledge base is next given and details of actual implementation include screen output from the program.
