The impact of the revised IEEE Std. 519 on power systems evaluated using the 1981 standard

The author contends that the proposed IEEE Std 519 has more constraints than its 1981 predecessor. The new standard has distortion limits for power producers. The table has been expanded to list three entries for maximum individual harmonic voltage distortion based on the bus voltage at the point of common coupling. Current distortion limits are given. The table lists twenty-five entries for maximum individual current distortion and five entries for total demand distortion. These distortion limits are based on the short circuit current at the point of common coupling and the maximum demand load current. An analysis of a power system evaluated using the 1981 standard is made based on the proposed standard.<>
