Opis:
This paper describes a control circuit for the active power filters working with three-phase AC power line. It describes logic circuitries as well as laboratory test results. The control circuit was realized with programmable logic devices, fast analog-to-digital and digital-to-analog converters. Proposed system working with open-loop control, it allows significantly simplifying its logic structure. Programmable logic devices do simultaneously a few independent tasks, so a control algorithm can be performing fast, improving considerably compensation dynamic. This paper includes results of laboratory tests of the active power filter consisted of proposed control circuit and a voltage-source converter.

Opis:
The paper deals with the new method of analysis, synthesis and experimentation of single-phase power active filters. By using a new particular transformation theory, the ordinary single-phase system can be transformed into an equivalent two-axes orthogonal one. The new original thought is based on the idea that ordinary single-phase quantity can be complemented bv fictitious second phase so that both of them will create an orthogonal system, as is usual in three-phase systems, in spite of [1]. Application of the above theory makes it possible to use complex methods of analysis as the instantaneous reactive power method, which have not been usable for single-phase systems so far. Both, the active and reactive powers can be determined by this way. Practical application of the method is outlined for the case of reference current determination for single-phase power active filter. The paper shows some examples of the simu-lution verification results, which proved a high accuracy and extremely fast response of the single-phase active filter with control, based on the introduced method. The effectiveness of proposed control algorithm is also demonstrated by experimental results, which were carried out on the single - phase active parallel filter, power rate of 25 kVA and controlled by 32 - bit Heating point digital signal processor TMS 320C31.

Opis:
The significant problem of compensator placement and sizing in electrical networks has been analyzed in the paper. The compensation is usually realized by means of passive or active power filters. The former solution is widely used mainly because of the economical reasons, but the latter one becomes more and more popular as the number of nonlinear loads increases. Regardless of the compensator type the most important goal consists in voltage and current distortion drop below levels imposed by standards. Nevertheless, the desired effects should be achieved with the minimum cost. So far a few objective functions have been proposed for this optimization problem. It is claimed that minimization of the compensator currents leads also to the minimum costs. This paper shows that such simplified approach could lead to suboptimal solutions and in fact a function g(·) reflecting the relation between the compensator size and its price must be incorporated into objective functions. Moreover, in this case it is very easy to compare solutions obtained using compensators offered by different suppliers - it is enough to change the function g(·). Theoretical considerations have been illustrated by an example of active power filter allocation and sizing.

Opis:
The considered shunt active power filter can be controlled not only to compensate non-active current in the supply source, but additionally to optimize energy flow between the source and the load. In such a case the filter shapes the source current to be active and simultaneously regulates its magnitude. The presented filter/buffer can operate properly even when the load contains AC or DC variable energy source of any characteristic. The device can optimize energy flow for a single load, but also for a group of loads as well. The distinctive feature of the employed control method of the filter/buffer is that certain changes of energy stored in the device are utilized as the source of information concerning the active current of the load. This control method is very flexible and can be implemented to nearly all structures of active filters, for DC, single- and multiphase circuits.

The aim of the paper is to demonstrate how to use sampled method of control of a shunt active power filter to maintain invariable power of a supplying voltage source, even though the supplied load varies randomly. The definition by S. Fryze of load current components is used as a basis for the construction of a family of shunt active power filters. The distinctive property of these filters is maintaining non-deformed source current in every one individually considered period T. The main features of the family of filters are described in the first part of the paper, which is devoted to DC circuit. In the second part, the results are implemented to a single- and a three-phase circuit. Additionally, some new features, which may be applied only for AC circuit, are discussed in the second part. All the presented waveforms are obtained using computer simulation tools.

The definition by S. Fryze of load current components is used as a basis for the construction of a family of shunt active power filters. The under discussion family of filters is designed to work synchronically with a time period T. The period T may be regulated in some range. The distinctive property of these filters is maintaining non-deformed source current in every one individually considered period T. Main features of the family of filters are described in the first part of the paper, which is devoted to DC circuit.

Opis:
The paper presents a concept of an active filter with energy storage. This solution can be used for the compensation of momentary one phase high power loads with discontinued power consumption (e.g. spot welding machines). Apart from the typical filtering capabilities, the system’s task is also the continuity of the input power from the feeder line and limiting its fluctuation. The proposed by the author’s solution can produce measurable economic benefits by reducing the rated power necessary to energize periodically operating loads and improving the indicators of electrical energy quality. The developed method of active power surges compensation enables a flexible approach to requirements concerning the rated power of the point to which the periodically operating loads with high peak current value are connected. The tests were conducted on a simulation model specially developed in Matlab & Simulink environment, proving high effectiveness of the presented solution.

Opis:
The paper presents the idea of power electronics voltage controlled current source (VCCS) which is able much more precise mapping of its output current in a reference signal, compared to a typical converter solution. It can be achieved by means of such interconnection of two separate converters that one of them corrects a total output current towards a reference signal. An output power of auxiliary converter is much lower than an output power of main one but its frequency response is extended. Thanks to continuous work of this converter also pulse modulation components in a total output current are minimized. In the paper an exemplary application of a current source, as an execution block of active power filter (APF), is presented.

Opis:
In the paper the analysis of a three-phase hybrid active power filter stability has been presented. Configuration with a single tuned passive filter was used as an example. However, the analysis can be applied to similar configurations of hybrid filters with closed loop control. The article presents a model of the analyzed system in the frequency domain. The division of the model into two independent systems, for positive and negative components, allowed to apply the Nyquist criterion for the stability analysis in this case. As a part of the analysis, the effect of delays, control signal filter parameters, and passive filter parameters have been examined. Based on the presented stability analysis, system parameters for the experimental model of a hybrid power filter have been selected. Finally, experimental results confirming the validity of the analysis have been shown.

Opis:
Different APFs (Active Power Filter) interact with each other when multiple APFs are connected to the grid, and the interactions deteriorate the control performance of APFs and even lead to system instability. This paper presents a method to analyze the dynamic interaction of multiple APFs in a weak grid. This method uses the Norton equivalent principle to establish the mathematical model of a single APF. The mathematical model of the multiple APFs connected to the grid is set up based on the single APF mode. The RGA (Relative Gain Array) principle is used to analyze the interactions among multiple APFs. Besides, this paper analyzes the effect of changing circuit parameters and controller parameters on the change of the interactions. The strategy of weakening and eliminating the interaction is proposed based on rational selection and combination of parameters. Analysis, along with time domain simulation and experimental results, is presented to verify the feasibility and effectiveness of the proposed method and strategy.

Opis:
One of the most important drawbacks of the three phases five-level NPC (Neutral Point Clamped) Active Power Filter (APF) is the neutral point balance. As the consequence, the capacitors voltages of the input DC bus of the APF are not equal which constitutes the major limitation for the use of this power converter. In order to stabilize these DC voltages, it is proposed in this paper to study the cascade constituted by three phases three-level PWM rectifier-clamping bridge filter-five-level NPC APF. In the first part, the authors present a topology of five-level NPC Voltage Source Inverter (VSI), and then, they propose a model of this converter and its PWM control strategy. In the second part, the modeling and control of three-level PWM current rectifier is presented. In the third part, to remedy to instability problem of the input capacitors DC voltages of the APF, the authors propose feedback control of the three-level PWM rectifier followed by clamping bridge filter. After that, the sliding mode regulator used to control the active filter is developed. The obtained results are full of promise to use this topology of APF in high voltage and high power applications.

Opis:
This paper describes a Fuzzy Logic approach to Shunt Active power filter (SAPF) versus Hybrid Active Power Filter (HAPF) using Simulink. Here hysteresis controlled PWM method is applied to the SAPF and HAPF as a current controller and Fuzzy logic controller as a inverter dc voltage controller. To reduce harmonics, Shunt Active Power Filters (SAPFs) are used with various control schemes, but Hybrid Active power filter is a power electronic device which has both the characteristics of passive power filters and active power filters, which helps in cancelation of the harmonics by producing compensating signal. The fuzzy-hysteresis controller is designed and its simulation results are presented for both the filter types, showing acceptable THD results for the word length used in the fixed-point computations involved in the switching sequence generation. The results of the above controller are compared with the Indirect current controller.

This paper presents an analysis of the properties of pulse width modulator with a single (symmetrical regular sampled PWM) and double (asymmetrical regular sampled PWM) control sampling of the input signal (low-frequency control input wave) in presence of a triangular auxiliary signal. In this paper, a comparison of the characteristics of these modulators used in the control system with a linear proportional controller is presented. The article provides the relations derived for the maximum amplification of regulators for which the control system operates stably. Analysis results have been confirmed by simulation and experimental studies of a commercial active filter installed in an industrial plant.
