MATHEMATICAL-MODEL FOR CONSTRUCTING A POWER-SYSTEM EQUIVALENT-CIRCUIT FOR CALCULATION OF STEADY-STATE AND TRANSIENT CONDITIONS

A basis for mathematical equivalent models of networks, taking into account the latest experience in the problem of simplifying the equations describing the electrical networks of power systems, is described. Two program complexes are described for forming equivalent computing models based on industrial experience. Correlated examples are given of calculations on real electrical networks with the purpose of deriving a general model and recommendations for its use with an IBM PC for steady-state and transient conditions.
