Sentence examples for ac sides from inspiring English sources

The obtained results indicate that the proposed method can detect and locate correctly different type of faults in both DC and AC sides of the GCPV plant.

If that a modest harmonic current at the resonance frequency will cause a relative high dc harmonic voltage, correspondingly, it causes significant harmonic voltages on the ac sides.

Due to the design of the systems with high pass filters on the ac sides, the high order harmonics could be suppressed.

The design procedure is initiated with deriving allowable operating ranges for the passive elements in dc and ac sides of the converters and continued to find the switching frequency for both converters.

In order to isolate the fault from the grid AC side, the AC circuit breaker at the fault terminal is tripped.

Open image in new window Fig. 3 Three-phase short-circuit fault at MMC AC side Open image in new window Fig. 4 Fault isolation by blocking of MMC and tripping of AC circuit breaker.

In summary, the fault currents at the DC side, ac side and in the converter would exist all the time.

When an AC fault occurs at the converter AC side of one terminal of the MTDC system, say the most severe three-phase short-circuit fault, the voltage at the faulted point will drop, and the fault current will flow into the faulted point from both the grid AC side and the MMC AC side.
