ON-LINE COMPUTATION OF ELECTRICAL ENERGY QUALITY RATES
Abstract
The authors propose to analyze the quality rates of electrical power with the help of microprocessors and specially designed software. In order to compute the rates the authors created a technique to complete a database of rates through digital on-line filtering. The suggested technique of application of KalmanBucy filter method for filtering measured data in the problems of quality analysis of the power, which enters the network after DC voltage transformation from the outlet of autonomous generator for non-traction and non-transport customers into the AC current with the help of invertor, allows to analyze on-line electrical power quality rates. Using algorithm of digital filtering the authors have formed a sequence of values of a discrete function у = f(t). The numerical analysis of that function gives possibility to determine on-line all power quality rates as well as auxiliary rates, stipulated by state standard 13109-97.
