| 摘 要： | 为保证系统运行稳定,分析了220 kV高压电网线路采用双光纤通道保护方案:配置1套光纤电流差动和1套光纤距离(方向)保护。考虑电网结构、系统稳定、供电可靠等诸多因素,以分相电流差动保护与纵联距离保护作为两套主保护,以三段式接地距离和相间距离保护与零序电流保护作为后备保护,基本达到了工程要求。

| Abstract: | In this design,dual fiber channel protection program for 220 kV power lines are used,which sets a fiber current differential and a set of fiber distance(direction) protection.Comprehensively considering the network architecture,system stability,power supply reliability and many other factors sub-phase current differential protection and the longitudinal distance protection are chosen as two main protections,three grounding distance together with phase distance protection and zero-sequence current protection... |
