[Abstract]:In this paper, the problems of the AC distribution network and the superiority of DC power distribution have been paid more attention to, and the ideas and suggestions for constructing the direct current distribution network and the direct current network are put forward. As the innovation or change of the new generation of power grid, the DC power distribution network and the direct current network will lead to a series of needs research including the equipment and products of DC power equipment and appliances, DC conductors and cables, the planning, construction and operation of DC power distribution and direct current network, etc. A problem to be solved. The voltage class is the foundation of many research contents, but it has not been found that the current distribution voltage class and its evaluation theory and method have been reported. In this paper, the necessity of the study on the level of DC distribution voltage is described, and then the internal and external influences of the DC distribution voltage class are analyzed from the aspects of social development, economic development, load and power supply, operation economy, system security, etc. In this paper, the influence factors of the voltage class are obtained. The scheme of the voltage class of the medium and low voltage direct current distribution is given according to some factors. Then, the influence factors of the voltage class of the DC power distribution are divided by means of the explanation structure model method. In this paper, the direct influence factors of the voltage class are defined, the influence path of the influence factors is obtained, and the relation between the influence factors and the voltage class is obtained. On the basis of this, the evaluation index of the DC distribution voltage class is studied and analyzed, and the economy and the reliability evaluation are put forward. The evaluation index and evaluation method of DC distribution voltage class adaptability are given from the aspects of load development, power access, technology and equipment. Finally, the comprehensive evaluation flow of DC distribution voltage class is given.
