| Abstract: | 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. |
