变压器经济运行决策软件设计

为节约能源,降低配电变压器的运行损耗,分析了变压器经济运行的基本原理,考虑了变压器之间的特性差异和变压器负荷随着时间变化的特点,利用VC 程序分析变压器在不同运行方式下的经济运行点,实现智能化选择变压器的经济运行方式,如在一定的负荷条件下,变压器应该采用单台运行还是多台运行,在多台运行情况下,是并列运行还是分列运行等,实现从变电站采集数据到选择运行方式的智能化过程,并且通过数据和图表的形式直观、清晰地给出选择结果,为变电站提供一套良好的决策系统。通过工程实例验证,得出结论:在不同的负荷下,变压器的经济运行点不同,不同运行方式存在着不同的经济运行区,当负荷落在该经济运行区中,该种运行方式就为最经济运行方式。

Design of decision-making software for transformer economic operation

In order to save energy and lower transformer losses of distribution network,the principle of transformer economic operation is studied,the characteristic differences between transformers and the load change of transformer are considered,and the economic points under different operating modes are analyzed using Visual C for realizing the economic operation of transformers by intelligent selection of operating mode,e.g.for a particular load,one or more transformers should be put into operation,and they should operate in parallel or separately.As a suitable decision-making system for substations,the software realizes the whole intelligent process from data collection to operating mode selection,and displays the result distinctly with both data and chart.Engineering example shows that,different loads have different economic operating points,different operating modes have different economic areas.When load is within the economic area of an operating mode,the operating mode is the most economic operating mode of that load.
