摘要
电力网络中影响断点求取算法效率的关键步骤是简单回路的求取。在基于回路线性组合提出的形成简单回路的方法上,利用跟踪开关变位,在获得开关变量形式的基本回路矩阵基础上,利用一定的运算规则,形成电路系统结构中动态的简单回路;并应用同或运算对形成的动态简单回路加以处理,得到形成的简单回路相对应的开关变量函数,进而提出基于开关路径集的形成简单动态回路的新算法。算例证明了文中思想和算法的正确性。
The formation of all simple circuits is a pivotal step of influencing the efficiency of break point deter- mination algorithm. Based on the linear combination circuit, the formation of the simple loops is put forward. In the tracking procedure, after the formation of the circuit matrix as a function of the breaker status, the simple dynamic circuits are formed in the circuit system structure based on the certain algorithm. And the formed sim- ple dynamic circuits are dealed with by the operation of ＂Not Exclusive Or＂. At last, the breaker-path functions of the elements in the simple circuits are formed. The new method for forming the simple dynamic circuits based on the set of breaker-path functions is established. The results of the example demonstrate the effective- ness of the new method.
