清远电网稳定问题分析与稳定控制系统方案研究

Stability Problem Analysis and Stability Control System Project of Qingyuan Power Grid

在贤令山变电站主变压器检修时,清远电网存在着功角稳定与电压稳定问题。通过对清远电网各种典型故障的稳定计算,找出清远电网的安全隐患,并给出相应的控制措施,在此基础上提出了稳定控制系统配置方案。采取相关稳定控制措施后,清远电网稳定性大大提高。

During overhaul of the main transformer in Xianlingshan Substation, there existed the problems of power angle stability and voltage stability in Qingyuan power grid. Through stability computation of diverse typical faults in Qingyuan power grid, the hidden safety troubles in the grid were found out with corresponding control measures offered. On this basis, the configuration scheme for the stability control system was put forth. After taking relevant stability control measures, the stability of Qingyuan power grid was greatly improved.
