The low-frequency measuring method of voltage, current, power and signal processing application for compact PLC
This article presents the implementation of the low-frequency measuring method of current and voltage RMS values as well as active and reactive power of a two-terminal network, which is supplied by a sinusoidal voltage of 50 Hz. The implementation was made on a typical compact PLC-FX3G Mitsubishi Electric controller. This controller has a relatively low computing power, and when control tasks and measurements are performed simultaneously, the measurement method must be simple in order to match the limited computing power of the controller. This article describes how to implement the low-frequency measuring method onto the controller. It also presents the laboratory set for testing the controller and application. The paper also presents the results of measurements and calculations, in particular the impact of measurement time delays on errors of the RMS voltage and current values as well as active and reactive power values.
