This paper investigates the design,analysis and simulation of a Distribution-STATic COMpensator(D-STATCOM) for non-linear load Composite(harmonic and reactive power) compensation on a three phase bus network. Composite compensation is achieved by implementation of a p-q controller, which monitors the load current and injects equal amplitude and opposite phase compensation currents to neutralize...

Nowadays, the proliferation of non-linear loads (especially power electronics equipment) leads to deterioration of the quality of voltage waveforms at the point of common coupling (PCC) of various consumers. In view of the wide spread use of harmonics-sensitive electronic equipment, power conditioning equipment is becoming more important for both electric utilities and their customers. With rap...

In this paper performance analysis of various hybrid reactive power compensators (RPC’s) at the inverter AC sides of a line commutated converter (LCC) based multi-terminal HVDC (MTDC) transmission system, feeding weak AC networks, is carried out to thoroughly gather the mechanisms of interactions between an HVDC system and weak AC systems. The hybrid compensator is realized by equally mixing th...

––This paper describes the performance of a Flexible Alternating Current Transmission Systems (FACTS) device, namely, STATic synchronous COMpensator (STATCOM) based on 48-pulse Voltage Source Converter (VSC), for the mitigation of voltage-dip caused by the starting of a high power induction motor.

In emerging electric power systems, enlarged communication often lead to the situations where the structure no longer remains in secure operating region. The flexible Ac transmission system (FACTS) controllers can take part in an important role in the power system security enhancement. However, due to high capital investment, it is necessary to locate these controllers optimally in the power sy...

As one of effective regulation methods, static synchronous compensator (STATCOM) has been widespread used to regulate dynamic reactive power and solve dynamic voltage stability problems into powergrid. Through the analysis of mathematical model, cascaded STATCOM, which is constructed by several cascaded H-bridges, is a nonlinear, multivariable, strongly coupled system. It will make difficulties...
