本文基于matlab开发环境，利用鱼群算法对30节点的电网进行无功优化(Reactive Power Optimization Based on fish swarm algorithm in 30 node grid)

说明：  对曲线进行拟合，使得最后拟合的数据与元数据的误差最小(The curve fitting, so that the final fitting of the data with the metadata minimum error)

MATLAB 空间直角坐标系与大地坐标系转换(MATLAB space rectangular geodetic coordinate system conversion)

svm的一种特征选择方法，基因选取算去，减少特征数量，减少运算时间，也可提高运算精度(svm a feature selection method, gene selection operator to reduce the number of features to reduce the computation time, but also can improve the calculation accuracy)

这个是用来计算白噪声测试的，特别适用于振动台试验。编程简单，测试也比较符合预测值。(This is used to calculate white noise, especially for shaking table test. The programming is simple and the test is more consistent with the predicted value.)
