Застосування малих гідроелектростанцій для підвищення ефективності експлуатації розподільних електричних мереж

Abstract

Master's degree qualifying work is sanctified to the features of the use of the small hydroelectric power stations for the decline of losses in the electric system and them the simultaneous use with other refurbishable energy sources. A normative base that sets the value of cost of generuting of electric power the different types of RES is analysed. The base method of optimization is choose the method of surplus of variants for determination of the optimal set power of sunny and hydroelectric power stations in electric networks on the criterion of a minimum of losses of electric power. Methods are certain and the algorithms of decision of task of optimal power-level of generuting are worked out for reduction of losses in distributive electric networks. By a calculable experiment the method of numeral integration of losses of electric power is confirmed taking into account the charts of change of loading of EN and generuting of RES. In the division of labour and safety protection in emergencies harmful and dangerous factors are analysed on the hydroelectric power station and measures are offered on the protection of personnel. The modes of operations of electric networks with refurbishable energy sources settled accounts by means of programmatic complex "VTRATY", that is worked out on the department of the electric stations and systems of the Vinnytsya national technical university.
