摘要:Electric power industry as an indispensable energy supply in daily life and production, which is the main motive force of equipment operation in the industrial times. Therefore, in order to meet the development needs and ensure the safety of power supply, it is necessary to optimize and transform the power grid. So that energy conservation and security of supply and demand can be ensured. In this paper, the short-circuit calculation and optimization design of distributed power distribution network are studied deeply, aiming at improving the performance of power grid and promoting the rapid development and transformation of power industry.
