综合介绍励磁系统运行可靠性的重要性。结合漫湾电厂励磁系统运行过程中发现的一些隐性故障、异常情况,通过运行巡视检查、检修试验等方式,逐步发现存在的问题,同时针对性的予以解决,提高励磁系统的可靠性。随着电力网络的不断发展和壮大,发电、输电、配电以及用电负荷的网络结构已经越发的复杂,而且发展速度越来越快,电网在提高电力系统动态、静态、暂态稳定方面提出了更高的要求。对于电源品质、故障情况下的响应速度、供电可靠性等方面要求越发苛刻。随着励磁控制系统自动化水平、磁场断路器等元器件稳定性不断提升,因设计缺陷或主设备故障带来的问题已经越来越少。然而实际运行过程中总是会出现一些其它方面的问题,威胁系统的安全稳定运行,消除励磁系统隐蔽性缺陷就显得越发重要。通过整理、分析励磁系统实际运行过程中的隐形故障,能够为本行业的工程人员提供较好的参考,提升电力系统运行的稳定性、可靠性。
Comprehensive introduction of the importance of the reliability of the excitation system. Combined with some hidden faults and anomalies found during the operation of excitation system in Manwan Power Plant, the problems existing in the inspections and overhaul tests are gradually discovered and solved in a targeted manner to improve the reliability of the excitation system. With the continuous development and expansion of power networks, the network structure of power generation, transmission, distribution and electricity load has become more and more complex, and its development speed is getting faster and faster. The power grid proposed in terms of improving the dynamic, static and transient stability of the power system A higher requirement. For the power quality, fault response speed, reliability and other aspects of the more demanding requirements. With the automation of the excitation control system, the stability of magnetic circuit breakers and other components continue to improve, the problems caused by design defects or main equipment failures have been less and less. However, there are always some other problems in actual operation. It is more and more important to threaten the safe and stable operation of the system and eliminate the hidden defects of the excitation system. By arranging and analyzing the invisible faults in the actual operation of the excitation system, it can provide a good reference for engineering staff in the industry and improve the stability and reliability of the power system operation.
