摘要
针对戴维南等值参数在暂态过程中不断变化的实际情况,提出基于时域仿真的戴维南等值参数跟踪计算方法。该方法没有基于任何假设前提,计算得到的戴维南等值参数精度高,克服了现有计算方法在系统内部发生扰动时精度差的缺陷,并在PSD-BPA暂态稳定程序中得到实现。3机10节点系统和2008年华中电网丰大方式的仿真结果表明,基于时域仿真的戴维南等值参数计算方法,能保证戴维南等值参数跟踪计算的结果准确、有效,可以广泛应用于电力系统的系统分析与控制。
The calculation method for Thevenin equivalent parameters based on time domain simulation was presented in consideration of parameter variation during transient process. This method which was not based on any of assumptions, was of high accuracy, and overcame the defect the existing methods have that it can＇t calculate precisely when disturbances occur within the system to be equivalent. And the calculation method has been implemented in the PSD-BPA transient stability program. The results of the 3-generation 10-bus system and some operation scenarios of central China power grid in 2008 showed that the algorithm can guarantee the tracking Thevenin equivalent parameters are accurate and effective, and it can be widely applied to the power system analysis and control.
