摘要
电网中功率因数及三相不平衡是影响供电的重要因素 ,使用电力电容器作为执行器件对电网中功率因数及三相不平衡实施综合补偿 ,具有较高的实用价值。简单介绍了电网中功率因数及三相不平衡综合补偿原理。利用神经网络具有自学习能力的特点 ,设计了一个三层神经网络将其运用于电网补偿之中。文章给出计算机仿真及初步的实验结果。实验结果说明了使用神经网络实现三相不平衡与无功综合补偿的有效性。
The power factor and three phase imbalance effecting on power net are the important factors in power supply quality.It is of great value to use the power capacitance as performing device for compensating power factor and three phase imbalance in power net.The compensation principle of power factor and three phases imbalance in power net is introduced.Using the NN(neural network) feature in learning ability,one three layers NN is used in power integration compensating system.The simulation results are given.The results explain the validity of this system .
