摘要

提出一个具有变量范围约束的电力系统潮流新模型和计算方法，即模型中变量的取值可以是不等式约束确定的范围。介绍了广义逆理论和方法，并应用于求解新模型。新模型不仅可使潮流计算更方便，还可以更清楚地揭示电压变化范围与无功补偿功率之间的关系，运用该方法可以根据对电压变化范围的要求计算出所需的无功补偿配置容量。通过算例验证了算法的有效性。

Abstract

A new model and associated algorithm of power flow calculation with constraints of changing range of variables by inequality equations are presented. Theory and applications of generalized inverse of matrices are introduced and used in resolving the new model. The new model can not only simplify the power flow calculation， but also reveal the relationship between the variation of voltage and reactive power clearly. Hence it can be used to determine the reactive power compensation capacity to be installed to satisfy the requirement of system voltage. The validity of the algorithm is demonstrated by case studies in the paper.
