Vector analysis and control of advanced static VAR compensators
The advanced static VAR compensator (now widely known as the static condenser or STATCON) uses a high power self-commutating inverter to draw reactive current from a transmission line. Two fundamentally different types of invertor can be used for this purpose, one providing control of output voltage magnitude and phase angle, and the other having only phase angle control. For each of these type...
متن کاملAn Intelligent Voltage Controller for Static VAR Compensators
The paper presetrrs a novel AI-rule based itrtelligeirt conrroller for fired capacitor-thyristor controlled reactor (FC-TCR) static VAR Compensator (SVC). The brrelligenr rolrage regulator is based on the concept of the error escrrrsiorr plarie where the stubilizing actiow is scaled by the magnitude of the excursion voltage error I'ector, irr order to etuure adequate compensation. The proposed ...
متن کاملImplementation of Passive Filters for Harmonics Reduction
In recent years there has been widespread use of power electronics devices and nonlinear elements in rectification and switchgear applied to various areas of power system. Power systems contain levels of harmonics which can no longer be ignored by engineers, planners, energy conservationists and economists due to the presence of non-linear loads. A simulated case study of distributed system in ...
متن کاملOptimal placement and sizing of Static Var Compensators in power systems using Improved Harmony Search Algorithm
This paper presents the application of the improved harmony search (IHS) algorithm for determining the optimal location and sizing of static Var compensator (SVC) to improve the voltage profile and reduce system power losses. A multi-criterion objective function comprising of both operational objectives and investment costs is considered. The results on the 57-bust test system showed that the I...
متن کاملImproving Pacific Inter-tie Stability Using Existing Static VAR Compensators and Thyristor Controlled Series Compensation
The paper summarizes new control designs developed at Washington State University for the control of existing SVC’s, and TCSC owned by Bonneville Power Administration. The new controls are primarily aimed at improving transient stability of the WSCC western electric power system. The proposed controls are heuristic and are nonlinear. They are shown to be very effective in increasing the operati...
