【摘要】：电力系统安全域因能提供丰富的安全信息而越来越受到重视。分析了电力系统静态安全域边界空间结构,认为安全域边界由所有对应于静态安全约束的子边界构成。针对电力系统的超高维数和强非线性,提出了一种用超平面组来近似安全域边界的方法。该方法线性化系统节点功率注入方程,建立节点电压幅值与相角和节点功率注入之间的线性关系,进而得到代表所有对应于静态安全约束的子边界的超平面组。基于节点功率注入安全域边界超平面,分析了系统运行点的安全性和裕度,利用空间向量分解法给出了超长方体安全域的概念。通过分裂电力网络,把断面潮流安全域等价为分裂后两子网络分裂节点安全域的交集,间接地获得了断面潮流安全域边界超平面组。算例结果表明,所提方法能有效地求取电力系统静态安全域边界。
[Abstract]:The security domain of the power system is being paid more and more attention for providing abundant security information. The boundary space structure of the static security domain of the power system is analyzed. It is considered that the boundary of the security domain is composed of all the SUBBOUNDARIES corresponding to the static security constraints. A superplane group is proposed for the superplane and strong non linear power system. The method of security domain boundary. The method linearized the node power injection equation, established the linear relationship between the node voltage amplitude and phase angle and the injection of node power, and then got the hyperplane group representing all the sub boundary corresponding to the static security constraints. By using the space vector decomposition method, the concept of super long cube security domain is given by using the space vector decomposition method. By splitting the power network, the cross section power flow security domain is equivalent to the intersection of the split node security domain of the split two sub network, and the cross section flow security domain boundary hyperplane group is obtained indirectly. The results show that the proposed method can have a new method. The static security domain boundary of the power system is obtained.
