摘要
武钢110 kV电网有13个变电所,26路采用的是光纤高频距离、零序保护。光纤电流纵差保护,通过完善微机光纤纵差保护、提高微机保护的灵敏度和可靠性,确保武钢电网的安全运行。
The technologies of high frequency distance, zero order protection and optical fiber current differential protection are already applied in the 13 transformer substations and 26 high voltage electric cable lines in the 110 kV electric net of WISCO. As the results the sensitivity and reliability of the computer protection is raised by improvement of the PC optical fiber differential protection and therefore the safety and smooth running of the electric net of WISCO is ensured.
