由于抽水蓄能电站的水库库容相对较小 ,又具有抽水、发电工况频繁转换的特点 ,从安全运行和优化调度角度出发 ,要求在运行中对水库的库容、水位作即时查询 ,并对库水位的变化历时进行快速预报。以广州蓄能水电厂为例 ,介绍实现这一过程的原理和方法 Due to the relatively small storage capacity of the pumped storage power station and the frequent conversion of pumping and generating conditions, it is required to make real-time inquiries on the storage capacity and water level of the reservoir during operation from the perspective of safe operation and optimal operation. Changes in water level lasted for rapid prediction. Taking Guangzhou Pumped Storage Power Station as an example, the principle and method to realize this process are introduced
