Abstract ▼ AI-Helper

Automatic reclosing is a typical protection method in power distribution systems for clearing the temporary faults. However, it has a fatal weakness in regards to voltage sags because it produces successive voltage sags. In this paper, we explored successive impact of voltage sag due to the automatic reclosing of power distribution systems. The actual tests of low voltage loads were accomplished for obtaining the susceptibility of voltage sags. The final results of the test yielded power acceptability curves of voltage sag, and the curves were transformed the 3-dimensional CBEMA(Computer Business Equipment Manufacturer Association) format. For the quantitative evaluation of the impact of successive voltage sags, an assessment formulation using the voltage sag contour was proposed. The proposed formulation was tested by using the voltage sag contour data of IEEE standard and the results of the test. Through the case studies, we verified that the proposed method can be effectively used to evaluate the actual impact of successive voltage sans.

attempt. For the verification of effectiveness of the proposed evaluation formulation in (6), we accomplish the actual test for obtaining the power acceptability curves of low-voltage loads and the case studies using voltage sag contours and the results of the actual test.
For this purpose, we accomplished the actual tests of the low voltage sensitive loads for obtaining the susceptibility of voltage sags. Form the results of the test, we produced the CBEMA format curves for individual and successive voltage sags, and the 3-dimensional power acceptability curves were presented. We proposed the assessment formulation of the successive voltage sag using the performance contour of voltage sags and the statistical probability of the reclosing successf니 1 ratio.
the actual experiment. The object of this test was to obtain the power acceptability curve of the low-voltage sensitive loads for individual and successive voltage sags. The actual test for customersz loads is a very effective method to obtain the direct results, but it is impossible to accomplish the test of whole loads.
We proposed the assessment formulation of the successive voltage sag using the performance contour of voltage sags and the statistical probability of the reclosing successf니 1 ratio. The proposed formulation was tested by using the stochastic data of voltage sag contour in IEEE standard and actual test results. Through the case study, we verified that the proposed method can be used for expecting the probability of the disruption of each load for a year and deciding the cumulative effect of successive voltage sags.
