Embodiment Construction
[0020] see figure 1 , the application provides a topology configuration method for distribution network wide area self-healing system, including the following steps:
[0021] Step 11: Number all intelligent terminals in the distribution network wide area self-healing system.
[0022] The distribution network wide-area self-healing system refers to a number of closely related substations as a region, and the protection devices in the region are interconnected through optical fibers, and through information sharing, according to the topology structure, the fault point can be quickly located, and the regional power grid can be intelligently restored. protection and control. The distribution network wide-area self-healing system can rely on the multi-point information of the power system to quickly, reliably and accurately remove faults, and at the same time analyze the impact of fault removal on the safe and stable operation of the system, and take corresponding control measures...

The present application provides a topology configuration method for a wide-area self-healing system of a distribution network. The method includes: numbering all intelligent terminals in the wide-area self-healing system of a distribution network; obtaining the numbers of all the intelligent terminals and the type of intelligent terminal; according to the number of each intelligent terminal and the type of the corresponding intelligent terminal, according to a preset algorithm, generate all switch numbers, lines and busbars in the distribution network wide area self-healing system number; according to the number of each intelligent terminal and the type of the corresponding intelligent terminal, deduplicate the numbers of all lines and buses in the wide area self-healing system of the distribution network; according to all the switch numbers and The processed line and busbar numbers, configure the switch, connection relationship between lines and busbars, and generate a topology matrix. The method can automatically generate all switches, lines and bus numbers of the wide-area self-healing system of the distribution network, and obtain a topology matrix, which saves time and effort, and improves work efficiency and accuracy.
Description
technical field [0001] The present application relates to the field of relay protection of power systems, and in particular to a topology configuration method for wide-area self-healing systems of distribution networks. Background technique [0002] Electricity is one of the most widely used energy sources in people's production and life. With the progress of the times, people have higher and higher requirements for power supply performance, thus putting forward higher requirements for the reliability of distribution network. Traditional distribution network automation systems usually use segmented or inverse time-limit overcurrent protection to isolate faults, which have disadvantages such as inaccurate fault location, wide power outage range, slow power supply recovery speed, and inability to accept a large number of distributed new energy sources. [0003] In order to improve the power supply reliability of the distribution network, reduce the scope of power outages when ...
