摘　　要：运用发电偏离电量与网损分配的数学模型,通过特定电网对电量偏离的特征和影响进行了计算与分析.由于电源点离负荷中心的电气距离不同,形成了两种典型的发电偏离电量网损微增特性.按照发电偏离电量对电网运行的影响,提出了3种偏离程度的认定与划分判据.此方案已被电力部门采纳,经实际运行,证明是切实可行的.This paper presents a model for analyzing and calculating the incremental electric power loss under the situation of generating deviation occurring in one or several grid nodes. Aimed at a designated grid, two kinds of incremental power loss curves are studied. Taking into consideration multi-load level, we carry out three types of generating deviation standards and describe their characteristics. The described method has been used in practice and proved to be feasible.
