密云水库调蓄工程多级泵站峰谷运行情况研究

Study on Peak-Valley Operation Condition in Multistage Pump Station

为进一步提高密云水库调蓄工程运行管理中的工程效益,降低工程运行成本,文章结合北京市峰谷电价情况,根据历年工程调度运行经验及各泵站间渠道最大调蓄容量,提出泵站机组峰谷调度运行方式。泵站机组按照电价峰谷时段精准开停机组,并合理调整流量,通过计算验证,各项数据满足工程调度运行要求,为多级泵站节能降耗平稳运行提供了新思路。

The operation mode of the pump station unit peak and valley dispatching is proposed based on the peak-valley electricity price in Beijing according to the project dispatching operation experience over the years and the maximum regulation and storage capacity of each pump station channel in order to further improve the engineering benefit in the operation management of Miyun Reservoir Regulation and Storage Project and reduce the operation cost of the project.Pump station units are accurately turned on and off according to the peak and valley periods of electricity price.The flow is adjusted reasonably.All data meet the requirements of project dispatching and operation through calculation and verification.A new idea is provided for the stable operation of multistage pump stations with energy saving and consumption reduction.
