Capacity determination method of distributed power generation of 10kv distribution line based on tolerance penetration ratio

Abstract

The invention provides a 10 kV distribution line distributed power supply constant method based on the tolerance penetration ratio. This method collects the characteristic parameter data of the distribution line in the area where the target line to be rated is located; divides the variation range of the characteristic parameters of various distribution lines into H Two small areas of characteristic parameters with the same size; extreme cases are taken in each small area of ​​characteristic parameters, non-ground state conversion is performed on the ground state line model, and the tolerance permeability ratio is calculated through the tolerance permeability ratio calculation model; cable and overhead lines are summarized separately Tolerable penetration ratio in the small area of ​​each characteristic parameter forms a tolerance penetration ratio recommendation table; according to the characteristic parameters of the object line to be determined, refer to the tolerance penetration ratio recommendation table to configure the distributed power supply capacity. The invention avoids the complex modeling and calculation process of conventional distributed power planning and optimization, can guide the distributed power capacity configuration of the same type of power distribution lines, and has intuitiveness and versatility.

Description

technical field [0001] The invention relates to the problem of capacity determination of distributed power sources of power distribution lines, in particular to a method for capacity determination of 10kV distributed power sources based on the tolerance penetration ratio. Background technique [0002] The application of distributed power is mainly connected to the distribution network, and its connection makes the traditional network of single power source radiation type become an active network with multiple power sources scattered and distributed. When the distributed power supply is unreasonably connected, it will cause problems such as voltage over-limit and fluctuation, which will affect the safety, economy and reliability of the distribution network. Therefore, it is necessary to adjust the capacity of the distributed power generation in the distribution network. [0003] The capacity determination of distributed power generation is a large-scale multi-constraint non-...
