摘要:
分布式并网光伏电站自动化监控系统在电站的安全生产中占有关键地位,针对过程层设备通讯故障的研究分析,根据光伏电站电气设备的运行机理及特性,并结合一定的现场故障处理经验,将过程层通信故障原因归纳为光纤环网风暴、接地网故障和逆变器共模干扰,并提出工程中相应的处理方法,为国内大型分布式并网光伏电站故障处理提供一定的参考依据,推动光伏产业的健康发展。
Abstract:
The automatic control system of distributed grid-connected photovoltaic (PV) power station plays a critical role in the safe production. In this paper, the author analyzed the communication malfunction of the process level equipment, and based on the operation mechanism and features of the electrical equipment in PV power station as well as the on-site troubleshooting experiences, concluded that the reason of such malfunction was the optical fiber netstorm, grounding grid failure, and inverter common-mode interference. In addition, some corresponding solutions were proposed, providing references for processing the failure in the domestic large-scale distributed grid-connected PV power station, which will promote the healthy development of the PV industry.
