Intelligent adjusting method for technical water supply system in pumped storage power station
The invention provides an intelligent adjustment method for a technical water supply system in a pumped storage power station, and the method comprises the steps: taking unit temperature prediction as an intermediate variable for connection, making full use of the real historical operation data of the pumped storage power station, and building a temperature prediction model of the technical water supply system through building a long-short term neural network improved based on a sparrow search algorithm; establishing a technical water supply system pipeline model in Fluent to obtain a mapping relation between the temperature and the recommended flow; on the basis of the research, establishing a mapping relation prediction model to simplify the modeling research process; finally, a temperature threshold value is obtained through calculation according to the improved Raida criterion, whether an alarm is given or not is judged, and recommended flow is given. According to the method, the temperature serves as an intermediate variable, great inaccuracy caused by direct flow prediction is avoided, a power station decision maker can better adjust the water supply flow in a technical water supply system according to the working condition change of the pumped storage power station according to a calculation result, and the water saving amount is effectively increased.
本发明提供一种抽水蓄能电站中技术供水系统智能调节方法，将机组温度预测作为中间变量连接，充分利用抽水蓄能电站真实历史运行数据，通过搭建基于麻雀搜索算法改进的长短期神经网络，建立技术供水系统温度预测模型；随后通过在Fluent中建立技术供水系统管道模型，得到温度与推荐流量的映射关系；在此研究基础上，建立该映射关系预测模型，以简化上述建模研究流程；最后通过改进的拉伊达准则计算得到温度阈值判断是否报警，并给出推荐流量。本发明将温度作为中间变量，避免了直接预测流量所带来的极大的不准确性，根据计算结果，电站决策人员可以更好的根据抽水蓄能电站工况变化，调整技术供水系统中的供水流量，并有效提高节水量。
