天津电网低压减载可行性方案研究

Feasibility Study on Under Voltage Load Shedding Scheme in Tianjin Power Grid

天津电网在华北电网中处于受端系统,具有典型城市电网的特点,电网电压稳定问题突出。通过对天津电网进行故障扫描分析,找出系统中的薄弱点,并在综合全国其它省网低压减载方案的基础上,提出天津电网低压减载方案。

Tianjin Power Grid is on the receiving end of North China Power Grid with typical characteristics of urban network and obvious voltage instability problem. Fault scanning and analysis of Tianjin Power Grid was made and weak links of the system were found. Based on the under voltage load shedding schemes in other provincial power grids across the country, the under voltage load shedding scheme for Tianjin Power Grid is formulated.
