摘要
分析了不同弱电源系统输电线路故障特征,针对华东500 kV系统的特点,明确弱馈回路应正常运行时应投入。提出了改进弱馈回路的建议,并根据线路在系统中的不同运行特点给出弱馈回路的实际配置。
The failure characteristics of the weak-infeed transmission lines are analyzed. According to the features of East China 500 kV system, it is pointed out that the weak-infeed circuit must be normally put into operation. Improvement suggestions for the weak-infeed circuit are proposed, and practical configurations for weak-infeed circuits are given based on their operational features.
