摘要

火电厂的柔性改造，降低了机组的最小技术出力。电网运营商可以选择不同的运行模式，这将影响电网的频率调节。考虑火电厂的柔性调整，建立了再热器汽轮机及负荷变频控制的数学模型。创建了两个场景并进行了仿真。结果表明，随着电力系统中受测机组的增加，无论是在独立控制区还是在两个互联控制区，频率偏差都明显减小。本文的结论对区域火电厂的运行具有一定的指导意义，以减小频率振荡的幅度。

An Analysis of the Effects of Flexibility Modification on System Frequency Regulation

With the flexibility modification of thermal power plant, the minimum technical output of units has been reduced. Different kinds of operating modes can be chosen by operators of power grids, which will influence the frequency regulation of power grids. The mathematical model of reheater steam turbine and load frequency control (LFC) are established considering flexibility modification of thermal power plants. Two scenarios are created and simulations are carried out. The results indicate that with the increase of units investigated in power system, the frequency deviation decrease obviously in both a stand-alone control area and two interconnected control areas. The conclusions presented here provide some guidance on operation of thermal power plants in regions to reduce the amplitude of frequency oscillation.
