基于人工智能的配变异常分析预警模式的研究

本文以分析预警配变设备异常状态为目的,研究基于人工智能的配变异常分析预警模式。从配变设备本体、电网环境与外部环境三方面分析配变运行状况数据,对相关数据实施数据清洗等预处理,导出对拟合模型产生影响的异常数据并将其清除,实现配变基础数据的整理;根据整理后的数据进行建模要素评估,选取设备老化、长期重过载、三相不平衡与温度过高这四个因素对配电异常风险进行评估与预警。在此基础上,选取收网算法确定人工智能技术中径向基神经网络模型的参数,利用确定参数后的径向基神经网络模型实现配变异常预警。测试结果显示该方法的预警精度达到96%以上,且采用该方法进行分析预警后,配变设备年故常率降低3.7%。

Configuration and kinematics analysis of locking-releasing mechanism for side-loaded lunar rover

In order to save space for storing precision equipments,lower the center of mass of Lander and reduce lunar rover's dimension constraint limited by mechanism of Lander,the locking-releasing mechanism of side-loaded lunar rover loaded outside Lander is presented,which is a kind of metamorphic mechanism.To ensure the working of this mechanism as the metamorphic process designed,configuration analysis of the locking-releasing mechanism is carried out,and topological structures are described by Huston lower numbered arrays.A kinematic mathematical model of the mechanism is established through homogeneous transformation matrix.The kinematic simulation validates the feasibility of the locking-releasing mechanism when the configurations are shifted from one to the other.
