IMPLEMENTATION OF KALMAN FILTERING ALGORITHMS FOR MICRO-COMPUTER DISTANCE PROTECTION ON A VECTOR SIGNAL PROCESSOR

介绍利用卡尔曼滤波算法实施微机距离保护的方法。该设计方案共分五个主要部分：故障检测，故障后电流和电压的估计（滤波），故障分类，区域计算和故障定位。并着重介绍了在向量信号处量器ＴＭＳ３２０上完成卡尔曼滤波算法的方法。实验结果表明，该方案的计算精度、收敛速度和计算工作量俱称满意。

This paper presents a micro─computer distance protection scheme using Kalman filteringalgorithms. The scheme can be divided into five major components : fauIt detection , postfault current andvoltage estimation(filtering),fault classification , zone computation , and fault location. The paper focuseson the implementation of filtering algorithms on the Vector Signal Processor(VSP)TMS320. The test resultsshow that the precision, convergency speed and the quantity of the calculation are all satisfied.
