Allowable current error of three-phase inverter

How to compensate a scaling error in a three-phase inverter?

In this paper, simple compensation methods for the current measurement errors due to the scaling gain error of the current sensor and non-simultaneous sampling error are proposed for three-phase inverter applications. The scaling error can be compensated offline simply by turning off one phase of the inverter.

What happens if a photovoltaic inverter fails?

Grid failures may cause photovoltaic inverters to generate currents (“short-circuit currents”) that are higher than the maximum allowable current generated during normal operation. For this reason, grid operators may request short-circuit current ratings from vendors in order to prepare for failure scenarios.

What happens if the C-phase leg of the inverter turns off?

Assuming that two current sensors are used and the c-phase leg of the inverter turns off, the constant current flows from the a-phase windings to the b-phase windings, and the c-phase current is zero, as shown in Fig. 2.

What is the inverter fault diagnosis dataset?

This dataset includes three key features, namely Ea, Eb, and Ec, representing the energy calculated from the fault currents for phases A, B, and C, respectively. By utilizing the Inverter Fault Diagnosis dataset, researchers can perform various tasks related to fault diagnosis, such as classification, pattern recognition, and anomaly detection.
