继电保护整定计算在电力系统广泛采用分布式整定计算模式，在继电保护整定计算模型拼接中，图形拼接部分存在着接线混乱的问题。深入研究了一体化继电保护图形拼接的特点，结合厂站电压等级，提出了基于改进遗传算法的继电保护一体化图形拼接方法。为了提高图形拼接的效率，采用按电压等级分层寻优的方式确定最优厂站布局。最后通过实际算例验证了该方法的快速性及有效性。

Distributed protection relay value setting is applied in China. There is a graph chaos problem in protection relay model splicing process. The characteristic of integrated relay splicing is studied deeply, and combined with the substation voltage level, a substation locating method based on improved genetic algorithm is proposed. To enhance the graph splicing, a voltage level based method is applied. At last, a practical example is used to validate the effectiveness of the method.
