Problems solved by technology

Among the methods based on the safe and reliable operation of the distribution network, the relatively rough method is the capacity-load ratio method, which reflects the power supply capacity of the distribution network as a whole by calculating the capacity-load ratio; The calculation method of power supply capacity of the power grid is mainly based on the interconnection relationship of the main transformer and the load transfer between substations, etc., to investigate the load transfer capacity of the distribution network under the N-1 verification. And it is mainly developed for the main transformer level, and less involved in the power supply capacity of other types of equipment

Abstract

The invention relates to a power supply capability evaluation method of a regional power distribution network. The power supply capability evaluation method comprises the following steps of 1, building a power supply capability evaluation index system of main equipment of the power distribution network; 2, building a total power supply capability evaluation index system of peering equipment; and 3, building a power supply capability evaluation index system of a power distribution system. Technical scheme provided by the invention aims to build the power supply capability evaluation system to the power distribution system from single equipment on the basis of relatively less topological information, power supply capability evaluation models are respectively proposed with regard to three levels of the single equipment, the peering equipment and the power distribution system, and each level comprises three evaluation indexes, namely, maximum power supply capability, power supply capability storage and power supply capability margin.

Description

technical field [0001] The invention relates to the field of power supply capability of a distribution network, in particular to a method for evaluating the power supply capability of a regional distribution network. Background technique [0002] The power supply capacity of the distribution network refers to the ability of the distribution network to carry loads under the premise of ensuring safe operation. Solving the problem of weak power supply capacity of the distribution network is an urgent task for the development of the power grid. Therefore, a scientific and reasonable evaluation of the power supply capacity of the distribution system (ie, load supply capacity) has become the key to the fine evaluation and planning of the current power grid. [0003] In the existing research, there are mainly two types of calculation methods for the power supply capacity of the distribution system, namely, the method based on the power flow calculation of the distribution network a...
