| 摘 要： | 在进行电力系统广域保护和控制时,确定系统大范围时滞稳定域及其边界规律意义重大.文中给出一种求解电力系统大范围时滞稳定域的有效方法:首先利用参数变换技术,将大范围时滞稳定域边界的求解,转换为对有限参数空间的搜索和平移过程,大大减少了时滞稳定域边界的计算量;进一步,利用四点插值法,通过对稳定域边界上临界点实施微扰以确定稳定域的构成和边界性质;最后,利用典型时滞系统和WSCC 3机9节点等系统验证了所述方法的有效性.

| Abstract: | An effective method for computing the large scale time-delay stability region of a power system is presented. Firstly,a transformation is introduced to the original time-delay equations. Secondly,an iterative process in a limited subspace is performed to find the core boundary of stability region,which is then cloned,panned and converted into the time-delay space to locate the boundary of power system stability region. Thirdly,a four-point interpolation process is used to distinguish the stable and unstable... |
