摘要

介绍了一种基于级联相关网络的谐波源检测系统的设计。注入电流的谐波潮流计算母线电压和总谐波失真(THD)。电压的THD指标用于确定在电力系统中的测量位置。在计量总线上，它表明在不同负载下电压的谐波分量会在频域中形成特定的模式，并且可以用来创建CCN的训练样例。仪表规划有助于减少仪表数量，从而减少训练示例。以14母线电力系统为例，进行了计算机仿真，验证了该系统的有效性。

Multiple harmonic source detection for power system with cascade correlation network

This paper presents the design of a harmonic source detection system with cascade correlation network (CCN). Harmonic power flow with current injection model calculates bus voltages and total harmonic distortion (THD). THD indices of voltages are used to determine measurement placement in the power system. At metering buses, it shows that harmonic components of voltage under various loads would form particular patterns in the frequency domain, and can be used to create training examples for CCN. Meter planning is helpful to reduce the number of meters and hence the training examples. With 14-bus power system, computer simulations were conducted to show the effectiveness of the proposed system.
