This paper designed a multifunction single-phase power quality analysis and control system, which used the single chip microcomputer STC12C5A60S2 as the core, and the power quality detection chip CS5460 A. The system detection includes voltage, current, frequency, phase, and can calculate the active, reactive and power factor. Harmonic analysis uses the EMD algorithm. And this system with microcomputer protection and control of reactive power compensation function. The experiment results show that the system can detect and control power quality effectively.
