摘要:
为了满足电力系统继电保护联合整定计算的需求，同时解决我国继电保护整定计算年度边界等值不满足实际电网变化的问题，本文提出了基于模型拼接的全电网模型作为继电保护整定计算的基础数据，采用全模型应用于电力系统继电保护整定计算工作。本文首先介绍了现阶段继电保护整定计算中存在的问题以及模型拼接的理念；然后介绍了基于边界厂站、支路识别的模型拼接流程；最后通过算例验证了该方法的实用性和有效性。
In order to realize the integration of relay protection calculation and solve the problem of distinc-tion between the boundary contour and the network, full network model based on model splicing is proposed in this paper, which can be used in the setting calculation work. First, problems in the setting calculation of relay protection and the conception of model splicing are introduced; then, the flow of model splicing based on boundary station and branch identification is presented; at last, an example is used to verify the feasibility of this method.
