A distribution network load transfer auxiliary decision-making analysis method

Abstract

The invention, which belongs to the technical field of power systems, relates to a method for assisted decision-making and analysis of distribution network load transfer. The method comprises: step one, carrying out security checking on distribution network load transfer; step two, carrying out reliability checking of distribution network load transfer; step three, carrying out correction checkingon the distribution network load transfer; and step four, selecting an optimal plan of the distribution network load transfer. According to the invention, defects of long load transfer time, low efficiency and poor reliability due to the reliance on manual rough calculation of the regulation staff in the conventional distribution network load transfer are overcome; the distribution network load transfer can be carried out safely, reliably, and efficiently; and the safety production of the distribution network and the high-quality service level are improved.

Description

technical field [0001] The invention belongs to the technical field of power systems, and relates to an auxiliary decision-making analysis method for distribution network load transfer. Background technique [0002] The distribution network directly faces thousands of households and is a key link to ensure the reliability of power supply for users. Due to the complex structure of the distribution network, a large number of line components, and the harsh operating environment, frequent faults occur in the distribution network lines. In order to ensure the reliability of power supply, in addition to the failure of the distribution network itself, it is necessary to transfer the load of the distribution network when dealing with accidents such as emergency elimination of the upper-level power grid and internal faults in the substation. [0003] At present, the on-duty control personnel mainly rely on the current load of the line, through manual rough calculations, and combined ...

AI Technical Summary

Problems solved by technology

[0003] At present, the on-duty control personnel mainly rely on the current load of the line, through manual rough calculations, and combined with operating experience to determine the transfer plan. The transfer efficiency is low and the reliability is poor. The load transfer and supply control personnel have increased the huge work pressure, which makes the safe production of the distribution network face a severe test

It is impossible to conduct in-depth research and judgment on the load of the line only by the manual calculation of the control personnel to determine the transfer line. When the load is heavy, it is easy to cause the overload of the transferred line. At the same time, it is difficult to comprehensively analyze the operating conditions and special methods of the transfer line. If the fault rate is very high, it is easy to expand the accident, which seriously affects the reliability of power supply of users and the good image of high-quality service of power grid enterprises.
