Kolsun V. The energy datum improvement ways of supply systems of power-consuming plants with controlled-velocity electric drive

The thesis is devoted to improving power indices in power-consuming industries by means of model problem solution and power processes calculation of different electric drive systems. Theoretical fundamentals of power indices analysis, calculation and prediction under instability conditions are developed. High-performance group electrical drive systems are founded by means these fundamentals. Main power dependences were taken into account plants loading. New mathematical modeling approaches are grounded on the base of known calculation methods analysis and estimation of inter-influence conditions and electromagnetic compatibility and differential equations calculation by mean special elaborated method of solving derivative. It is developed the uniform algorithm of automatic poly-variant solving. The algorithm makes provision for determining current and voltage harmonics of net which supply converters group. Phase and linear voltage drops for different events may be calculated by mean the algorithm. Experimental researches are lead. Practical achievement of this systems and registration devices of such systems are made.
