“…The reactive power compensator is capable of suppressing the voltage fluctuation and flicker. Off-the-shelf var compensators in distribution network include fixed capacitor (FC) [1,2], static var compensator (SVC) [10], and static synchronous compensator (STATCOM) [11], etc. Among these devices, the STATCOM is widely used for its multiple functions, such as grid voltage fluctuation suppression, and unbalanced load compensation.…”

With the wide application of non-linear loads and the large-scale access of distributed energy generations based on power electronics equipments, power quality problems in the distribution network are increasingly serious with new characteristics. Further in-depth research is of great significance in theory and practice. This paper provides an overview of power quality analysis, compensators, and control technologies under the new situation of smart grid. It focuses on the topologies and control methods for power quality conditioners, especially new characteristics of power quality and applicable control technologies in microgrids and distributed power plants. Finally, trends and prospects of power quality control technology are introduced, which is important to achieve security and efficient operation of the smart grid.

“…Static VAR compensator (SVC) using thyristor switched capacitor (TSC) and thyristor controlled inductor (TCI) schemes have traditionally been used for reactive power compensation [1][2][3]. TSC and TCI schemes have a major disadvantage that they generate current harmonics.…”

“…Where these measures include discrete conductor transposition, a systematic basis for transposition design has been reported, and the superimposed contribution of saturated-reactor compensators has been quantified [4]. The purpose of this paper is that of extending this recent work [3,4] to thyristor-controlled forms of reactive-power compensator [5][6][7][8][9][10][11], and of developing models in this case which can provide a corresponding degree of representation in analysis to that now available for saturated reactor compensators. Modelling methods for thyristor-controlled compensators have been reported previously [8][9][10], primarily in their relationship to the contribution of compensators to network voltage control.…”

Of the different control objectives of reactive-power compensators based on thyristor-controlled reactors, the advances in modelling methods and computer simulation of the paper relate specifically to the mode of voltage-magnitude control in which each phase is controlled individually. For this control objective, a comprehensive analysis formulation is developed in phase-variable notation in a form which can directly be incorporated into Newton-Raphson network analysis in which each phase retains its separate identity. The main context of the development is that of the supply from transmission networks of loads of substantial imbalance between the separate phases. The analysis and evaluation facilities to which the developments of the paper can lead, provide means by which the response of compensators with individual phase-voltage-magnitude control functions can be investigated for the conditions of pronounced imbalance in steady-state primary system operation. Following the analysis derivations and the developments in phase-variable modelling for thyristorcontrolled compensators, a representative design investigation is given in the paper in which phase-to-phase loads are supplied from a section of a 220 kV network. In this particular application, the effectiveness of individual phase-voltage-magnitude control in lowering operating imbalance is quantified.
