“…13 consists of two inductor grounded single tuned LC filters which are tuned to filter the 3 rd , 5 th and 9 th and 11 th harmonics respectively and one directly grounded single tuned LC filter which is tuned to filter the 7 th harmonic. The designed components size of the MV LC filter package is given in Table VI. For the cost estimation, the data collected from [27] and the Internet are used. By the mentioned information, the overall cost of the tertiary winding filter and MV LC filter package is estimated as presented in Table VIII.…”

The widespread adoption of energy efficient but harmonic-producing loads in residential homes has led to increased injection of harmonic currents into transmission systems. In response to this situation, a novel filtering scheme that can reduce the harmonic penetration into transmission systems is proposed. The scheme utilizes the tertiary winding of a substation transformer to construct a tuned low impedance path for the harmonic currents. The proposed scheme is capable of trapping two zero-sequence harmonics and three non-zero-sequence harmonics simultaneously. Design procedure has been developed. Performance of the scheme is evaluated and demonstrated through simulation studies. In addition, economic analysis reveals that the scheme is a cost-effective solution in comparison with other applicable methods.Index Terms-Power quality, harmonics, passive filter.  0885-8977 (c)

“…A ZS voltage ( ) is applied to the filter. The Kirchhoff's voltage law (KVL) implies that in the secondary side of the transformer (1) where is the transformer secondary to primary winding ratio, is the power fundamental frequency (in radians per second), is the harmonic order, and and are the transformer winding resistance ( ) and leakage inductance ( ), transferred to the secondary side, respectively. From (1), the equivalent ZS impedance of the filter at harmonic order can be calculated (2) Next, the equivalent ZS circuit of the filter can be established as depicted in Fig.…”

This paper presents a technique to mitigate zero-sequence harmonics in power distribution systems. The method is based on the concept of passive zero-sequence harmonic filters. However, its basic configuration has been expanded to create a double-tuned filtering feature. This feature makes it possible to trap two harmonics with one filter and is especially attractive in solving harmonic-caused telephone interference problems. Furthermore, this paper has shown that common utility service transformers can be used to construct the filter. As a result, a practical and low-cost solution to mitigating zero-sequence harmonics has been found. A method for sizing and loading assessment of filters has also been developed. As an example application, the proposed filter package has been applied to mitigate a telephone interference problem. Issues, such as filter location, the number of filters required, and the effectiveness of filtering harmonics produced by distributed residential loads have been investigated. The results show that the proposed filter is a very promising technique to reduce zero-sequence harmonics in primary power distribution systems.

Considering the effect of the utility harmonic impedance variations on harmonic responsibility, a method based on piecewise bound constrained optimization is proposed in this paper to evaluate the load harmonic responsibilities. The wavelet packet transform is employed to determine the change times of the utility harmonic impedances. The harmonic monitoring data is divided into several segments where the utility harmonic impedances are considered as constants. Then, the problem of harmonic responsibility assessment under utility harmonic impedance changes are settled by the piecewise bound constrained optimization model. Furthermore, the interior point, the sequential quadratic programming and the active set algorithm are respectively adopted to calculate all the instantaneous harmonic responsibilities of harmonic loads. Finally, the weighted summation is used to calculate the total harmonic responsibility. To demonstrate the validity, simulation tests are carried out on an experimental circuit and the IEEE 13-bus distribution system.
