摘要
基于电力系统分析软件工具对潮流、短路进行定量分析,研究山西±800 kV雁淮特高压直流投产后直流近区220 kV电网潮流分布、短路水平等安全稳定特性,提出该区域存在的主要问题。从提高通道输电能力、增加汇集站布点、解决短路裕量不足等方面提出针对性的解决方案,为提高直流近区220 kV电网安全稳定性及220 kV电网电力外送组织能力提供可行的规划项目建议。
This paper quantitatively analyzes the power flow and short-circuit based on BPA software. The security and stability characteristics of power flow and short-circuit level of near-district 220 kV power grid after±800 kV Yanhuai UHVDC project is put into operation are studied, then the main problems in this area are put forward. From the aspects of improving the transmission capacity of the channel, increasing the allocation of the assembly stations and improving the short-circuit margin, corresponding solutions are put forward to provide suggestions for a feasible planning project for improving the security and stability of 220 kV power grid in the near district and the organizational ability of 220 kV power delivery.
