It has become one of the important tasks in the study on modern electric system. At first, this text has briefly introduced meanings, the current development and the main methods which the electric load forecasting are used. This paper aimed at the floatability which the load data had and the nature that neural networks model is easy to fall into part infinitesimal value and low iterative speed, this paper proposed a method based on neural networks and SVM. SVM can dispel the less summation and the larger single point errors of neural networks, and the neural networks could dispel the simplification of the model of the vector support machine.

本文首先介绍了电力系统负荷预测的意义、发展现状和主要方法；针对负荷数据具有浮动的特点以及神经网络模型算法容易陷入局部极小和迭代速度较慢的缺点，提出了一种基于神经网络和支持向量机的混合负荷预测方法，此方法能通过支持向量机消除神经网络的总和较小但单点误差较大的不利现象，而神经网络消除了支持向量机的模型简单问题。

I flow through valley, once seeing birds' twitter and fragrance of flower;I walk through lawn, once listenning to insect 鸣 frog drum;I walk through a hedge to fall, once seeing the head first put on lately green;I remit source, turning to make to fly spring waterfalls, washing face and combing hair foppery for ridges and peaks;I remit river's river, turning to make a wave blossom, giving the rock of near the bank sing to start to listen to of madrigal;I remit lake, turning to make gentle and soft bluish green wave, with green mountain together, the common ccolade sunrise month falls;Finally, I arrive at your in front, waiting for you accepting, I think you are a sea, you can't certainly because of my infinitesimal but the arrival of turn me down.

我流经山谷，看过鸟语花香；我走过草地，听过虫鸣蛙鼓；我走过篱落，看过枝头的第一抹新绿；我汇入泉源，化作飞泉瀑布，给峰峦梳洗打扮；我汇入江河，化作浪花朵朵，给岸边的岩石唱起动听的情歌；我汇入湖泊，化作温柔的碧波，和青山一起，共同迎接日出月落；最后，我来到你面前，等待你的接纳，我想你是海，你一定不会因我的渺小而拒绝我的到来。
