Research On Distribution Network Fault Location Based On Improved Whale Algorithm

The reliability and stability of power network are closely related to the normal operation of distribution network.Therefore,the problem solving and solving system is one of the most important research contents in the distribution system,which has a huge impact on the entire power system,especially the branch structure of the whole power grid becomes complicated when multiple distributed power sources are connected to the grid.It is of great value to find the fault location in the whole complex structure for the stable and reliable power supply of the whole power system.This paper begins with an introduction to Distributed Generations(DG)and the principle of grid connection.Then from the classification of distributed power sources,learn to master the mathematical models of wind power generation,micro gas turbine power generation,photovoltaic power generation and small hydropower.Understand the operation,generation mode,and advantages and disadvantages of each distributed power supply.This topic describes the impact on fault location after the DG is connected.Finally,by combining the Improved Matrix Algorithm and the Improved Whale Optimisation Algorithm to derive fault suspect segments from the Improved Matrix Algorithm,the hybrid algorithm is used to experiment with hypothetical single and multi-point fault cases in DG-containing distribution networks.algorithm is used as a control,demonstrating the strong performance of the hybrid algorithm when applied to DG-containing distribution network segment location problems.Figure[53]Table[17]Reference[80]...
