摘要
提出了以提高系统稳定性为目标的机组调差系数优化整定理念和方法。利用该方法得到的机组调差系数,可以在提高系统同步转矩的同时不会造成阻尼转矩的恶化,有利于系统在受到扰动时保持稳定运行;仿真算例证明了该方法的有效性;编写了用于专门针对机组调差系数优化整定的软件,并在实际电网中投入使用,取得了良好的应用效果。
An optimization and setting method for voltage adjustment ratio（ VAR） of generating unit was proposed,whose optimization object was to improve system＇s stability. Optimized VAR obtained by proposed method can improve synchronizing torque while not worsening the damping torque. Simulation cases proved the validity of the proposed method. Software for VAR optimization was developed and good application effect was achieved in practical.
