This paper proposes a static synchronous series compensator based on H-bridge inverter modules. Dynamic response of proposed system was analyzed by EMTP simulation, assuming that it is inserted in the 154-kV transmission line of one-machine-infinite-bus power system. The proposed system consists of 6 H-bridge inverter modules per phase, which generate 13 pulses for each half period of power fre...

The objective of this paper is to investigate the enhancement of damping the low frequency oscillations via tuning of static synchronous compensator (STATCOM) damping controller. The problem of STATCOM based damping controller is formulated as an optimization problem according with the time domain-based objective function which is solved by a quantum-behaved particle swarm optimization (QPSO) t...

There are several problems existing in the direct starting of asynchronous motor such as large current, reactive power absorption from network side and weak interference-resistance, etc. Aiming at this, a comprehensive energy-saving optimization model for voltage regulation based on static synchronous compensator (STATCOM) is put forward. By analyzing working principle operation performance reg...

this paper works on the concept of flatness and its practical application for the design of an optimal transient controller in a synchronous machine. the feedback linearization scheme of interest requires the generation of a flat output from which the feedback control law can easily be designed. thus the computation of the flat output for reduced order model of the synchronous machine with simp...

This paper presents a comprehensive survey on the mitigation of power quality problems such as low power factor, shortage of reactive power, poor voltage, voltage and current harmonics due to sudden change in field excitation of synchronous alternator, sudden increased in load, sudden fault occur in the system are solved by FACTS controllers such as STATCOM, DSTATCOM, and DSTATCOM. This paper a...

Wind power is one of the optimistic sources of energy generation among all the renewable energy sources. Hence for exploiting wind energy sources it must be connected to electric grid. Wind power inculation into grid affects power quality because of its fluctuating nature. This paper recommends a control scheme based on instantaneous SRF (Synchronous Reference Frame) theory for compensating the...
