The Research Of The Project Plan On Management Network System For Distribution Power Network

This paper roundly discusses the calculation, methods, management of electric power losses and the compliment of various solutions of deducing power losses from the practice of LongNan electric power company. Several valuable experiences are introduced and some effective improved solutions are presented. The status in quo and the problems of the analysis and calculation of losses in LongNan electric power company is introduced in detail. It analyzed in the round from the sides of data gathering, arithmetic simplifying, additional function of software, the solution of deducing loss, and so on. Especial in the side of deducing loss, lots of valuable suggestions are brought forward which help to the rebuilding, operation and management of the LngNan distribution network both from technical and managing views. On the side of theory losses, this paper brings up two improved methods to calculate theory losses based on the accurate distribution loadflow arithmetic. The one is to distribute load according to the monthly quantity of active load electricity, the power factor and the load curve of representative day. The other is to distribute according to the monthly quantity of active load electricity, the transformer capacity and the load curve of representative day. It proved that the arithmetic is valid. On the side of optimizing reactive compensation, a new concept of power-impedance quadrature and a new method of determining the points of reactive compensation according to power-impedance quadratures are presented. Combined with the bus voltage-reactive sensitive coefficients and the linear arithmetic of reactive optimization, the arithmetic and model of distribution network reactive optimization are achieved. It proved that the arithmetic is valid by the example. Based on the arithmetic of theory losses and distribution network reactive power optimization, simulation analysis is putted up on the practice system of Line 111, ChengXian,LongNan, the conclusion can be a reference to the rebuilding, operation and managing of practice system.
