摘要
介绍了2008年陕西电网220 kV及以上系统继电保护装置的微机化率、微机保护国产化率、线路纵联保护通道类型和保护配置等方面的情况。对2008年陕西省调管辖的继电保护装置动作进行统计,分析了造成相应继电保护装置动作的220 kV及以上系统一次设备故障特点,最后提出了建议。
The first part introduces the operating condition of 220 kV and above protective relays of Shaanxi grids in 2008, including the percentage of microprocessors based relays, market shares of domestic made microprocessor based product, types of communication channel and functional configuration of pilot protection relays. The second part describes the operation statistics of protective relays under Shaanxi provincial dispatch jurisdiction, analyzes the fault features of 220 kV and above primary equipment that caused its relevant protective relay operation. Finally some opinions and suggestions are presented.
