热电厂电气系统的继电保护综合自动化

Protective relaying synthetical automation in electric system of power station

利用远动终端RTU(remote terminal unit)和数据采集及监控SCADA(supervisory control and data acqui-sition)系统,将某热电厂10kV设备保护纳入综合自动化系统,即利用遥测、遥信、遥控改进原有保护系统存在的缺陷和不足,提高了10kV继电保护系统的管理水平.

Facing the weakness and defect of the protective relaying system,the paper discussed about using remote terminal unit, supervisory control and data acquisition system, and bringing the lOkv facility protection into synthetical automation system in a certain power station. Using telemetry,teleindication and telecontrol, the management level of lOkv rotective relaying was greatly increased and it ensured to realize the power supply stability and credibility in the power station electric system.
