基于一种改进BP网络算法的水轮机组故障诊断

The water turbine trouble diagnosis based on the improved BP network calculation

水轮机组状态监测与故障诊断系统,在水轮发电机组及电力系统中有着举足轻重的地位,提高水轮机组状态监测与故障诊断系统的准确性和及时性,对电力系统的安全运行具有重大意义。作者采用一种改进的BP网络算法,用于水轮机组状态监测与故障诊断系统中,试验表明,此方法改善了传统BP网络容易陷入局部最小点、网络收敛速度慢等不利因素,提高了水轮机组状态监测与故障诊断的准确性。

Water turbine state monitoring and trouble diagnosis system are very import in water turbine generator unit and electricity system,to improve their veracity and realtime has a significant for the safety run of the electricity system.The improved BP network calculation for water-turbine state and trouble diagnosis has improved the disbennifit factors of the traditional BP network easily run into local least point and network constringency pace slow etc.,and its veracity.
