The reliable operation of capacitors is very crucial for the reliability and stability of power supply. Based on the impedance frequency characteristics of capacitor and the FFT algorithm, this study extracts capacitor voltage and current at specific frequencies, enabling online monitoring of ESR and capacitance values.
The original operating status of the device enables non-intrusive online capacitance monitoring. Both simulation and experimental results demonstrated the effectiveness and accuracy of this method. The largest error was less than 0.6% under different power levels.
Vogelsberger et al. designed a small printed circuit board to monitor the equivalent series resistance (ESR) of DC-side capacitors in PWM converters. In , Jo et al. used the recursive least squares algorithm to monitor capacitance based on the capacitor voltage and the capacitor current.
It has no extra control or effect on control performance, which ensures the proposed condition monitoring method can be easily implemented. The remainder of this article is organized as follows. Section 2 introduces the basic operating principle of the MMC system. The capacitance condition monitoring method is presented in Sect. 3.
To identify abnormal capacitors, a condition monitoring method for capacitors is proposed in this paper using the cumulative sum detection of the sliding window algorithm. First, the bilateral cumulative sum algorithm of the sliding window is proposed to extract the switch-on time and switch-off time of the submodules (SMs).
