摘要
首先基于西安地区某办公楼空调季节的数据,进行了逐时温度和冷负荷的预测。然后,讨论了温度预测对负荷预测,负荷预测对离线优化的影响。结果表明,人工神经网络冷负荷预测的准确度不受异常天气情况的影响;而负荷预测的准确度直接影响非线性优化的结果;在线修正是至关重要的。最后,给出了实时控制中负荷预测及离线优化结果在线修正的实例。
Based on the hourly data of an office building in Xi'an, the hourly temperature and cooling load are predicted. Then, the influences of temperature prediction accuracy on cooling load prediction, cooling load prediction accuracy on off-line optimization are discussed. The results show that the accuracy of cooling load prediction using artificial neural network is not affected by the abnormal weather, the accuracy of cooling load prediction has direct influence on the results of nonlinear optimization. The online correction is of great value. Finally, an example of online correction of cooling load and offline optimization in real-time control is brought forward.
