在互联电力系统中，方向过电流继电器的协调最常基于固定网络拓扑进行研究。由于其复杂性和非线性，继电器协调制定为优化问题。配电系统经常会因网络拓扑和元件运行的动态变化而遭受后果。这种变化例如是发电机、线路和负载的输入和输出。结果是继电器的灵敏度和选择性降低。本研究的主要目的是协调方向过流继电器的自适应保护方案的基础上。第二个目标是提出蚁群算法的制定和它与遗传算法的比较。
The coordination of directional overcurrent relays is most commonly studied based on a fixed network topology within an interconnected power system. Due to its complexity and non-linearity, the relay coordination is formulated as an optimisation problem. Distribution systems often suffer consequences due to the dynamic changes of network topology and operation of elements. Such changes are for example the inputs and outputs of generators, lines and loads. The consequences are reduction of sensitivity and selectivity of relays. The principal objective of this study is to coordinate the directional overcurrent relays based on adaptive protection scheme. The secondary objective is to present the formulation of ant colony algorithm and a comparison of it with the genetic algorithm.
