Mathematical model for calculations of electromechanical transient processes (based on the example of OSH CHPP during modernization to an expected capacity of 100 mwt)

Abstract

The work carried out practical calculations and developed a mathematical model of the electromechanical transient process using the example of calculating short circuits during the modernization of the Osh Thermal Power Plant; it also contains quite complex calculations. But these calculations at the same time provide the basic concepts of designing calculations of current to the closure and networks of precise voltages: for selecting devices and conductors for setting up relay protection and automation, identifying high-voltage power lines on communication and signaling lines, choosing the number of neutral grounding in the system and for a number of other transient processes. Such designs as calculations of three-phase short circuit currents I short circuit, asymmetrical short circuit.
