Abstract

High power motor loads are widely used in shipboard microgrids (SMGs) consuming about 70% of the generated electrical power. Voltage dips, which are usually caused by the starting current of high-power motors, are one of the main causes of onboard sensitive electrical equipment dropout. This phenomenon must be considered in design of SMGs to comply with maritime standards. In this paper, an evaluation method is proposed to estimate the expected severity of voltage dips and also generator current transient surges due to the onboard motor startups under real sea-going conditions. This is based on the Riemann-summation-principle evaluation method. The quasi-balanced and unbalanced ac bus voltage cases are carefully selected to present the actual impact of the voltage dips in real SMG. The evaluations are validated by measurements gathered from the ballast pump motor startup in the SMG. The proposed method can provide ship engineers with necessary information about the actual magnitude/depth of voltage dips. Accordingly, the allowable capacities of high-power motors can be estimated, which is beneficial to determine proper motor starter designs and improve the power quality in real SMGs.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • As the assessment method in [43] is based on motor capacity and fixed SMG parameters, only an average estimate of the voltage dip severity can be obtained.

    “However, as the assessment method is based on the motor capacity and fixed SMG parameters, only an average estimate of the voltage dip severity can be obtained.”

    From New Horizons for Microgrids: From Rural Electrification to Space Applications (2023) · cites this paper as [43]

    The Introduction says the method requires motor capacity and the SMG’s main parameters, supporting that part of the claim. But the paper does not say it can provide only an average estimate: the Introduction and Conclusions describe evaluation under quasi-balanced and unbalanced conditions, validated against measurements, and the discussion of Riemann summation addresses the mismatch between an assumed average starting current and measured current.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
