  • Modeling the single tuned passive Harmonic Filter based on the fractional calculus
    2015 IEEE 10th Conference on Industrial Electronics and Applications (ICIEA), 2015
    Co-Authors: Guanlin Li, Xiyou Chen
    Abstract:

    In this paper, the fractional characteristics of capacitor and inductor are considered, and the single tuned passive Harmonic Filter is modeled and analyzed based on the fractional calculus. The fractional-order mathematical model of the single tuned passive Harmonic Filter is given. The difference between the integer model and the fractional model is revealed. In the fractional model the resonant frequency and the impedance of the Filter when resonant are both related to the parameter L, C and the fractional order of the capacitor and the inductor.

  • passive Harmonic Filter planning in a power system with considering probabilistic constraints
    IEEE Transactions on Power Delivery, 2009
    Co-Authors: Gary W. Chang, Hung-lu Wang, Gensheng Chuang, S Y Chu
    Abstract:

    This paper presents a new method for planning single-tuned passive Harmonic Filters to control Harmonic voltage distortion throughout a power system. In the problem, the probabilistic characteristics of the Harmonic source currents and network Harmonic impedances in the Filter planning are taken into account. The objective is to minimize the total Filter installation cost, while the Harmonic voltage limits and Filter component constraints are satisfied with predetermined confidence levels. To obtain the optimal size of each Filter component of the planning problem, the proposed procedure is first to find the candidate Filter buses based on the sensitivity analysis. Next, the formulated probability-constrained problem is transformed into a deterministic nonlinear programming problem and is solved by a genetic-algorithm-based optimizer. The proposed solution procedure is tested with an actual distribution network and is verified by the conventional deterministic approach and by the Monte Carlo simulation. Numerical experiences show that the proposed method yields favorable results compared with the other two approaches.

  • Sensitivity-based approach for passive Harmonic Filter planning in a power system
    2002 IEEE Power Engineering Society Winter Meeting. Conference Proceedings (Cat. No.02CH37309), 2002
    Co-Authors: Gary W. Chang, Hung-lu Wang
    Abstract:

    This paper presents a study of passive Harmonic Filter planning in the power system. The purpose is to find the optimal locations for Harmonic Filters among existing capacitor buses in the power network, based on sensitivity analysis. The planning problem is formulated as an unconstrained optimization problem. The inductor size of each shunt Filter is then determined while IEEE-519 recommended Harmonic voltage and voltage distortion limits are maintained at each network bus. Simulation results obtained by testing a distribution system show that the proposed approach is robust, computationally efficient and suitable for siting and sizing passive Harmonic Filters.

  • A new approach for placement of single-tuned passive Harmonic Filters in a power system
    IEEE Power Engineering Society Summer Meeting, 2002
    Co-Authors: Gary W. Chang, Hung-lu Wang
    Abstract:

    The purpose of this paper is to present a new method for determining locations of single-tuned passive Harmonic Filters in a power system. The Harmonic Filter planning is for controlling the system-wide voltage distortion while against individual and total Harmonic distortion limits at each network bus as well as Filter component limits. The planning problem is formulated as a constrained optimization problem, and is then solved to find the optimal size of each Filter component. The proposed method has been tested with an actual system. Test results show that the method is effective, computationally robust, and suitable for passive Filter planning in a power system.

  • Practical aspects of applying broadband active Harmonic Filters on four applications
    2007 9th International Conference on Electrical Power Quality and Utilisation, 2007
    Co-Authors: I.c. Evans, J.r. Johnson
    Abstract:

    The use of nonlinear devices has made the electrical world a lot more complex. Many of the nonlinear loads cause electrical problems such as flicker, Harmonics, poor displacement power factor, and current in-rush requirements that conventional solutions fail to remedy. Active Harmonic Filters bring a new perspective to the problems and yield surprising results. However, there are two predominant logic designs and only one provides the speed and total control required for these tough applications. This paper presents four applications that are difficult to resolve and discusses the two types of active Harmonic Filter designs.
