摘要
本文对电力系统经济运行中确定各发电厂在线控制的数学模型进行了分析。从原始数学模型的建立,通过最优潮流计算提供回归分析数据,到最后用逐步回归法确定出发电厂最优出力在线计算数学模型,进行了较详细论述。经过实例验算,说明了本文提出的数学模型公式简单,计算快,精度高,能满足在线计算的要求。
This paper analyses the math model of on-line controlle generators in economic dispatch, A more detailed description is given to the establishment of the proto-type math model, the advancement of regression data provided by the optimal calculation of power flows and the final determination of the on-line calculation math model for optimal output of each power plant through step-bysiep regression. Results from practical calculations show that the formulas of the math model presented here are smiple, the calculation speed is fast and its exactitude is high, thus meeting the requirements of on-line calculations.
