| Abstract |
The International Electrotechnical Commission(IEC) 61000-4-15 is a standard proposing techniques for a flicker meter test and measurement method. The IEC61000-4-15 ed1 announced in 1997 was not include tests for accurate verification. Also it was not explained flicker meter algorithm that can be directly applied to the other power systems. But the new edition of IEC61000-4-15 ed2 prescribes a variety of tests for verify flicker meter algorithm and it explains 'correction factor' used for measuring flicker in other power systems. It can measure flicker severity in 220V system by multiplying correction factor to the measured values with the 230V algorithm. This paper compared the method of measuring flicker severity in korea power system using the correction factor and the modified weighting filter, after verifying of digital flicker meter algorithm created by using matlab based on IEC61000-4-15 ed2. |
