摘要
智能建筑中的非线性产生的谐波影响电能质量,对用电设备危害大。为准确测量谐波参数,将随机子空间(SSI)理论运用于智能建筑的谐波检测。在MATLAB7.1/Simulink环境下搭建了具有典型负荷性质的智能建筑仿真模型。仿真结果表明,该方法检测精度高,简便易行,抗干扰能力强,具有良好的工程应用前景。
The non-linear harmonics of intelligent building influenced the power quality, it had great harm to the electrical equipment. In order to measure the harmonic parameters accurately , the random sub-space theory （SSI）was used in intelligent building harmonic detection. A typical load nature of the intelligent building simulation model was built in MATLAB 7. l/Simulink environment, the simulation results showed that the method had high precision and simple anti-interference ability, with good prospects for engineering applications.
