摘要
从220 kV分区电网短路电流控制的角度,在深入分析500 kV系统和地区电源提供的短路电流的基础上,以提高分区电网的受电能力为目标,探讨了以一个500 kV变电站带一片的220 kV分区电网的变压器配置原则及其与地区电源配置的关系,研究结论对合理利用500 kV站址资源,控制分区电网短路电流,提高分区电网的受电能力具有重要的指导意义。
Based on deep analysis of short-circuit current provided by the 500 kV systems and district power sources, the principle of transformer configuration in the 200 kV district grid when the whole 220 kV district grid is linked to one 500 kV substation is discussed, in order to improve the power receiving capability of the district grid, The relation between the 500 kV substation and the district power source configuration is also analyzed. The study results offer great guidance for reasonable utilization of 500 kV substation site resource, control of short-circuit current of district grids, and improvement of power receiving capability of district grids.
