This paper presents a novel harmonic identification algorithm of shunt active power filter for balanced and unbalanced three-phase systems based on the instantaneous power theory called instantaneous power theory with Fourier. Moreover, the optimal design of predictive current controller using an artificial intelligence technique called adaptive Tabu search is also proposed in the paper. These enhancements of the identification and current control parts are the aim of the good performance for shunt active power filter. The good results for harmonic mitigation using the proposed ideas in the paper are confirmed by the intensive simulation using SPS in SIMULINK. The simulation results show that the enhanced shunt active power filter can provide the minimum %THD (Total Harmonic Distortion) of source currents and unity power factor after compensation. In addition, the %THD also follows the IEEE Std. 519-1992.

“…Even the error of this method is given by a precise numerical * Correspondence: lvpinhrbust@163.com value. Compared to the old methods, which require large scales of power electronics, this new method can save money and is easily accessible [19][20][21][22][23]. Moreover, regarding the error, in the low asymmetrical degree the method discussed in this paper has more accurate value.…”

This paper is based on the definition of minor asymmetric degree and the relative position of the magnetic field. The relative position of the magnetic field is the angle between the positive and negative sequence magnetic fields.The corresponding relationship between the nonsalient pole synchronous generator steady performance and the magnetic field state is discussed when the generator operates at minor asymmetry. To analyze this corresponding relationship, the Taylor expansion formula with Lagrange remainder and symmetrical components is adopted. We study the relationship between the armature current and the relative position of the magnetic field, deducing the armature current expressions with second-order remainders. The law of the armature voltage is also obtained by phasor analysis. As an example, this paper executes two-dimensional finite element numerical calculations on a nonsalient pole synchronous generator.The result shows that the numerical calculation agrees with the deduced expression, which verifies the correctness of the expressions. In the meantime, during the process of deducing the expressions, a method of calculating the positive and negative sequence currents is proposed and their effective range is offered. When the generator works at maximum overvoltage and maximum undervoltage, the specific value of the relative position of the magnetic field is presented. This paper has important implications for generator running and protection.Key words: Minor degree of asymmetry, relative position of the magnetic field, nonsalient pole synchronous generator, positive sequence current, negative sequence current

“…In 1986, a combined system of a shunt active filter of SOOkVA, comprising voltage-source PWM inverters using bipolar junction transistors, and a shunt passive filter of 6600kVA was installed t o absorb harmonics generated by large capacity cycloconverters for steel mill drives [7]. In 1991, a shunt active filter of 20MVA, consisting of voltage-source PWM inverters using GTO thyristors, was developed for flicker compensation for arc furnaces with the help of a shunt passive filter of 2OMVA 181.…”

-This paper proposes a new power line conditioner consisting of two sinall rating series active filters and a shunt passive filter. The power line conditioner4ms at a general filtering system which will be installed at the point of common coupling in a power system feeding harmonic-sensitive loads and unidentified harmonicproducing loads. One of the two active filters is connected in series with the supply, while another is in series with the shunt passive filter. The purpose of the power line conditioner is to reduce voltage distortion at the connection point, and is to eliminate harmonic currents escaping into the system upstream of the connection point.A control scheme of the two series active filters which play an important role is described in this paper. Its filtering characteristics are discussed with the focus on voltage and current distortion. A prototype model of 2OkVA is constructed to verify the functionality and performance of the power line conditioner.
