调水系统突发断电情况下应急处置方案研究

Research on emergency disposal scheme of water diversion system under sudden power outage

调水系统运行中突发断电是常见的不利情况之一。为了给调度人员采取及时、有效的应对方法提供科学决策依据,有必要针对该情况进行应急处置方案研究。以山东省胶东调水工程典型渠段(辛庄泵站~黄水河泵站)为例,通过建立一维非恒定流数学模型对稳态运行的渠段全系统突发断电、上级泵站突发断电、下级泵站突发断电3种情况进行仿真计算。根据模拟结果提出了一系列应急控制方案,在保证输水安全的前提下,选择了最优控制方案。研究成果可为类似调水系统突发断电情况的调度决策提供有力依据。

In the operation of water diversion systems, sudden power outage is one of the common adverse conditions.In order to provide scientific decision-making basis for dispatchers to take timely and effective response methods, it is necessary to study the emergency response scheme.Taking the typical canal section of Jiaodong Water Diversion Project in Shandong Province(Xinzhuang Pumping Station to Huangshuihe Pumping Station)as an example, this paper established a one-dimensional unsteady flow mathematical model to simulate and calculate the steady-state operation of the canal section in three cases: sudden power outage of the whole system, sudden power outage of the upper station and sudden power outage of the lower station.According to the simulation results, a series of emergency control schemes were proposed, and the optimal control scheme was selected under the premise of ensuring the safety of water conveyance.The research results can provide a solid basis for the dispatching decision of sudden power outages in similar water diversion systems.
