Abstract

The power system is disturbed by electromagnetic interference and crosstalk between the transmission link layers in the transmission and distribution process, and it is easy to produce transmission distribution fault. In order to improve the efficiency of fault diagnosis, a method of fault diagnosis for power system based on neural network algorithm is proposed. The multi sensor quantization fusion method is used to carry out electricity. The transmission distribution signal in the power transmission link layer is extracted from the power system, and the transmission distribution signal is decomposed and the association rules are excavated. The spectral analysis model is used to extract the spectral characteristics of the transmission information of the power system, and the fault diagnosis and fault type identification are carried out according to the spectrum difference. The power system fault features are classified and identified by neural network learning algorithm to realize the optimal diagnosis of power system fault. The simulation results show that the method is more accurate and more efficient in the fault diagnosis of power system.
基于神经网络的电力系统故障诊断方法
电力系统在输配电过程中受到输电链路层之间的电磁干扰和串扰的干扰,容易产生输配电故障。为了提高故障诊断的效率,提出了一种基于神经网络算法的电力系统故障诊断方法。采用多传感器量化融合的方法进行电算。从电力系统中提取电力传输链路层的输配电信号,对输配电信号进行分解并挖掘关联规则。利用谱分析模型提取电力系统输电信息的谱特征,根据谱差进行故障诊断和故障类型识别。利用神经网络学习算法对电力系统故障特征进行分类和识别,实现电力系统故障的最优诊断。仿真结果表明,该方法在电力系统故障诊断中具有较高的准确性和有效性。
