| Abstract: | A PIC single chip microcomputer control Thyristor Switched Capacitor (TSC) for reactive power compensation is presented in this paper. This device uses the A/D function to obtain the frequency of electric network and sample the alternating signals (voltage and current) synchronously, then the RMS arithmetic is used to calculate the real-time data quickly. The compensative capacitors are encoded in the equivalent mode, which can switch on/off the capacitors circularly. The operation of the device proved that it can measure the parameters of power system fast and precisely, and achieve real-time reactive power compensation. |
