RCS-931B型线路保护在大坝发电有限责任公司的应用

Application of RCS-931B line protection in DaBa power plant

随着现代通信技术和继电保护技术的快速发展,RCS-931B型线路保护装置以其优越的保护性能已在超高压线路保护中得到了广泛应用。通过对RCS-931B型微机线路保护装置光纤电流差动保护原理和保护装置动作跳闸接点情况的分析,并结合该装置在大坝发电公司的现场应用情况,提出了该装置在现场应用中存在的几个问题,并对这些问题提出了有效的解决方法。

With the fast developments of the technologies of the modem communication and relay protection ,RCS-931B line relay protection device is used widely in the super-high voltage line relay protection.By means of the analysis of the principle of the RCS-931B fibre-optical electric current differential protection,and the analysis of the trip relays of RCS-931B line relay protection device,and the analysis of the application of RCS-931B line relay protection device in the DaDa Power Plant,the paper brings out several questions in engineering application and finds out the effective solutions to the questions.
