Analysi theory and method development of non-sinusoidal and non-symmetricregimes, power supply systems of industrial enterprises

Power supply of industrial enterprises are considered in the paper aiming at the analysis method development of non-sinusoidal and non-symmetric regimes of industrial power networks. As a result modelling methods of non-sinusoidal and non-symmetric regimes of industrial power networks, based on the description of the power supply system by the transformation coefficient matrix and the use of principles of the diacoptics and rarefaction of network matrixes, have been developed. Calculation methodologies and algorithms of non-symmetric regimes with uncomplete source data, statistical character of the deforming loading variation have been elaborated. The program complex for computers and recommendations for the control of electric power quality in power networks of coal sections have been introduced into operationAvailable from VNTIC / VNTIC - Scientific & Technical Information Centre of RussiaSIGLERURussian Federatio
