Properties, simulation and experimental investigation of the series-parallel active power filters

Abstract

In this paper introduced calculate method of active power filters passive components, simulation and experimental researches results of the series-parallel active power filter. Authors especially occupy oneself with analysis power flow between both active filters in UPQC system and nonlinear load. This problem is according to authors very important, because it makes possible to find optimum configuration of the hybrid UPFC and power of the additional sources elements.

Enhancing Electric Power Quality Using UPQC: A Comprehensive Overview

“…In [127], authors have used fault current limiter to reduce the UPQC rating particularly by limiting the excessive current during the event of a fault. Finally, it is found that throughout the development phases of UPQC, researchers have given equal importance to evaluate the control algorithm and overall UPQC system performance by experimental investigation [11], [14], [22], [23], [26], [33], [40], [42], [51], [52], [56], [57], [60], [63], [75], [80], [81], [89], [94], [97], [107], [109], [114], [116]- [118], [120], [129], [143]- [145], [147], [150], [155]- [157], [159], [161], [163], [164], [167], [168]. A 250-kVA UPQC system is developed at the Centre for the Development of Advanced Computing (C-DAC), Thiruvananthapuram, India [75].…”

“…During the system dynamic conditions, for example, sudden load change, voltage sag, the dc-link feedback controller should respond as fast as possible to restore the dc-link voltage at set reference value, with minimum delay as well as lower overshoot. The proportional-integral (PI)-regulator-based dc-link voltage controller is simple to implement and hence widely used by the researches [12]- [14], [16]- [20], [22], [23], [26]- [33], [36], [38], [40], [42], [46]- [48], [50], [54], [56], [60], [61], [64], [67], [68], [75]- [77], [81]- [84], [88]- [90], [92], [94], [95], [100], [103]- [105], [108], [109], [111]- [114], [116], [117], [119], [122], [124], [126]- [128], [130]- …”

Mitigation of Power Quality Problems Using Custom Power Devices: A Review

“…The aim of p-q control strategy is to find an effective strategy to compensate nonlinear loads using active power filters. Initially it was applied to balanced three-phase three-wire systems (3p3w) and then it was extended to unbalanced four-wire systems [18], [20], [21], [56], [61], [71], [92], [110], [116], [131], [133], [134], [136], [144], [146], [159], [161], [165], [167], [173], [180][181][182][183], [187], [188], [190], [202], [203], [213], [216].…”
