This article focuses the analysis on a static synchronous compensator (STATCOM) that operates simultaneously providing reactive power and several current harmonics of different frequencies (active filter or active impedance functionalities). Being more specific, this proposes general limitation method reduces references STATCOM whenever voltage limit converter is exceeded. In realistic operatio...

In recent years, there has been an increasing interest on applying advanced and intelligent control designs in power engineering area. As a heuristic optimization technique, Particle Swarm Optimization (PSO) is used for tuning the parameters of the STATCOM. Regulating the DC capacitor voltage in STATCOM is a common task and can improve the system dynamic. The nonlinear control is based on exact...

W DU and H F WANG Southeast University, Nanjing, China Abstract – Damping torque analysis is a technique developed based on classical control theory for the excitation implemented damping control in power generation, which has been widely used in engineering practice since it was proposed. This paper proposes the damping torque analysis for DC bus implemented damping control in power transmissi...

Most of the HVDC power converters with thyristor valves are assembled in a converter Bridge of Six pulse configuration. Converter transformers with one DC side winding as an ungrounded star connection and the other a delta configuration. Comparative studies of the two systems of HVDC CIGRE model without STATCOM and with STATCOM were performed. In these case, the consideration was the converter ...

Usually a STATCOM is installed to support power system networks that have a poor power factor and often poor voltage regulation. It is based on a power electronics voltagesource converter. Various PWM techniques make selective harmonic elimination possible, which effectively control the harmonic content of voltage source converters. The distribution systems have to supply unbalanced nonlinear l...

The output critical factor in establishing penetration levels active when assessing loading capabilities. Therefore, this article contributes enhancing understanding how static synchronous compensator (STATCOM) could be used as part system network. ...

This research article proposes a powerful fractional-order PI controller to mitigate the subsynchronous oscillations in turbine-generator shaft due to subsynchronous resonance (SSR) with flexible AC transmission system devices such as static synchronous compensator (STATCOM) and unified power flow controller (UPFC). The diminution of SSR is achieved by the raising of network damping at those fr...
