给出了光伏电源的调制技术和对锂电池的恒流、恒压和涓流的分阶段充电管理技术,并就遥测站RTU中高效、科学管理光伏电源、储能电池以及实现遥测站对光伏电源运行和充放电状态的远程在线过程检测进行了系统介绍.通过在广东佛山东风水库、广东云浮郁南大河水库等多个大坝的现场运行资料表明,该技术提高了遥测系统的透明度和异常预测能力,能够实现对RTU光伏电源系统的远程监测和诊断,确保水情测站的可靠运行.
The modulation technology of photovoltaic power supply and the phased charging management technology of constant current, constant voltage and trickle-flow of lithium battery are given. And the high efficiency and scientific management of photovoltaic power supply and energy storage battery in RTU of telemetering station, Power operation and charge-discharge status of the remote on-line process testing were systematically introduced.Through the field operation data of a number of dams in Foshan, Guangdong Dongfeng Reservoir, Guangdong Yunfu Yunan Dahe Reservoir shows that the technology improves the transparency and abnormal telemetry system Predictive ability, can realize the remote monitoring and diagnosis of RTU photovoltaic power system, to ensure the reliable operation of hydrological stations.
