Abstract

This paper deals with the tuning of power system stabilizers based upon an estimation procedure properly tailored for online applications. The growth of renewables in modern power systems imposes constant verification of the current operating condition and the effective tuning of power system stabilizer parameters to comply with a satisfactory damping factor of general system behavior. More specifically, an online procedure is proposed for the estimation of the current operating point and the consequent tuning of the parameters of the power system stabilizers. The estimation procedure combines the system’s dynamic response to a probing signal with the available measurements of power and voltage at the generator terminal side. The parameters of the current operating point are then derived through the least squares minimization between the measurement and power deviations. At the aim of the parameter tuning procedure, with respect to the estimated operating point, proper modeling that considers the presence of damper windings within the design methodology is proposed for better describing the dynamic performances. The proposed design procedure can combine both the specifications in the frequency domain of the phase compensation and those relating to the appropriate location of the eigenvalues of the dynamic matrix of the system. In the numerical application, the proposed approach is shown to be very effective in terms of current operating point estimation and consequent tuning of the power system stabilizer parameters in the range of interarea oscillations and local oscillations, thus counteracting the renewed requirements for stability issues in modern power systems.

基于参数动态估计的电力系统稳定器在线调整
本文论述了如何根据为在线应用量身定制的估算程序调整电力系统稳定器。现代电力系统中可再生能源的增长要求对当前运行状况进行持续验证,并对电力系统稳定器参数进行有效调整,以符合一般系统行为的令人满意的阻尼系数。更具体地说,我们提出了一种在线程序,用于估算当前运行点,并据此调整电力系统稳定器的参数。该估算程序将系统对探测信号的动态响应与发电机终端侧可用的功率和电压测量值相结合。然后,通过最小二乘法最小化测量值和功率偏差,得出当前运行点的参数。在参数调整过程中,为了更好地描述动态性能,针对估算出的运行点,提出了在设计方法中考虑阻尼绕组存在的适当建模。所提出的设计程序可以将相位补偿频域中的规格和与系统动态矩阵特征值的适当位置有关的规格结合起来。在数值应用中,所提出的方法在当前工作点估算以及随后在区域间振荡和局部振荡范围内调整电力系统稳定器参数方面非常有效,从而应对了现代电力系统对稳定性问题的新要求。
