Abstract
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.
Highlights
Economic development depends on electricity, so doing a good job of grid security is the core topic which is faced by the current power industry
The distributed power supply is very common, we define it as the power supply which is relatively close to the user system and its capacity value is relatively small
According to the actual investigation and the interface form of distributed power supply when it is connected to the distribution network, the distributed power supply can be divided into three kinds, one is based on the synchronous generator distributed power supply, the second one is based on the asynchronous generator distributed power supply, and the third one is based on the distributed power supply of PWM inverter
Summary
Economic development depends on electricity, so doing a good job of grid security is the core topic which is faced by the current power industry. In this process, we should pay attention to the optimization of the original network, and constantly change the existing shortcomings to improve energy efficiency and reduce the occurrence of accidents as far as possible. In order to reduce the safety accidents which are caused by short-circuit problems and ensure the high quality and efficiency of the power supply, the distribution network short-circuit calculation should be done very well to ensure the accurate, reasonable and effective calculation. In the course of research, according to the years of experience, the author summarized the relevant theores and the research results and gave the specific ideas for the corresponding problems, which lay the foundation for power grid optimization
