Adaptive Kalman Filtering for Computer Relaying of Power Systems

该项目是先前资助的将卡尔曼滤波应用于电力系统继电保护的项目的继续。更新涉及几个不同的领域，包括使用扩展卡尔曼滤波(以适应非线性模型)、包含故障安全分析、采用最小时间方法对电力系统部件进行数字保护、识别系统范围内干扰的严重程度以及计算(识别)故障位置。研究内容包括串联补偿线路、多端线路、高阻抗故障、变压器定位、动态安全评估和使用矢量信号处理器实现卡尔曼滤波。

This project is a continuation of a previously funded project on the application of Kalman filtering to power system protective relaying. The renewal addresses several different areas including the use of the extended Kalman filtering (to accommodate nonlinear models), the inclusion of fault security analysis, digital protection of power system components with a minimum time methodology, identification of the severity of system wide disturbances, and the computation (identification) of the fault location. Included in the study are series compensated lines, multi-terminal lines, high impedance faults, transformer location, dynamic security assessment and evaluation, and the use of vector signal processors in the implementation of the Kalman filter.
