电网备自投自适应建模方法研究

Research of self-adapted modeling methods for the BATS

传统的备自投建模由于要考虑各种电网的复杂结构及运行方式变化而导致模型描述很复杂,维护量大难以实用化。提出一种新的备自投自适应建模方法,利用模型分解的方法把一个复杂的备自投分解成几个基本备自投单元,减少模型设计的复杂性。并开发了一个新的电网自动拓扑搜索算法,实时自动分析更新备自投模型,让备自投的模型能够'自适应'电网的运行方式变化。实例分析证明该方法简洁实用,可以完全仿真实际备自投的复杂动作逻辑。

Due to the complexity of the power grid architecture and operation mode, the traditional modeling method for Busbar Automatic Transfer Switch （BATS） is hard to be practical. This paper proposes a new auto-adapted BATS modeling method, which decomposes a complex BATS into many BATS units decreasing the complexity of the modeling design, and then designs a new grid topology searching algorithm to achieve a real-time and automatic analysis of the BATS model, which makes the model automatically adapt to the change of power grid. The practice analysis proves that this method can completely simulate the complex action logic of the real BATS.
