Load Transfer Analysis of Regional Power Grid Based on Expert System Theory

Abstract

Load transfer technology plays a crucial role in regional power grid because it can significantly reduce the loss caused by fault and improve the reliability of power supply. Firstly, this paper introduces the typical connection mode of Jiangsu power grid, and makes a brief analysis of its operation mode. Secondly, the power failure range of each equipment in the station is analyzed to determine the search direction of the transfer path. Finally, combined with the expert system theory, this paper studies the transformer fault, bus fault and line fault respectively to determine effective load transfer strategy and give a load transfer plan that suitable for the regional power grid. The field operation shows that the method proposed in this paper is feasible, which can effectively transfer the power loss load caused by equipment fault in the power grid, and can ensure the safe and stable operation of the power grid.
