变电站改扩建中的变电一次设计分析

A design analysis of substation in substation expansion

在供电系统内部,变电站的核心存在意义就是进行电压变换、电能分配和接纳、电流流向控制等,其间不同等级电压都将借助特定线路连接至该类位置点,形成健全样式的电网。为了确保电网整体运行实效性,提升后期供电质量,满足日益增长的负荷需求,就必须对变电站进行改扩建。

In the internal of power supply system, the core of substation existence significance is for voltage conversion, power allocation and admission, current flow controlling and so on, during which different voltage levels will make use of the specific line to connect to the point, forming a sound pattern of power grid. In order to ensure the effectiveness of the overall operation of the power grid, to enhance the quality of the power supply, to meet the growing demand for the load, it is necessary to change the expansion of the substation.
