This Paper deals with digital simulation of FC-TCR, which can enhance the Power Quality of a power system. Reactive power is controlled by using tapped inductor system. This system reduces THD in the line current. Smooth variation of reactive power can be obtained by varying the firing angle of TCR. This circuit eliminates switching transients and improves the life of the capacitors. The simula...

This paper presents a study of the dynamic performance analysis of an Advanced Static Var Compensator (ASVC) using a three-level voltage source inverter. The analysis is based on the modelling of the system in the d -q axis. The dynamic behaviour of the system is analysed using P-spice (Simulation Program with Integrated Circuit Emphasis) as a simulation program. Various transient simulation re...

This paper presents a terminal voltage control of a wind turbine Self Excited Induction Generator (SEIG). The wind turbine induction generator system is proposed to supply an isolated static load under widely varying conditions. The terminal voltage had been regulated by adapting the value of the excitation capacitance from Static VAR Compensator (SVC) using Artificial Neural Network (ANN) cont...

A strategy is presented to minimize the voltage total harmonic distortion when controlling a multilevel converter to act as a static var compensator. Use of resultant theory has enabled the complete set of solutions to be found for switching a multilevel inverter’s power electronic devices at the fundamental frequency while eliminating the lower order harmonics. A scheme is also presented to re...

This paper investigates the performance of line commutated converter (LCC) based monopolar HVDC transmission system feeding a weak AC network with hybrid reactive power compensators (RPC’s) at the inverter AC side. The hybrid compensator is an equal mix of any two of the following compensators: synchronous compensator (SC); static var compensator (SVC); static synchronous compensator (STATCOM)....

This paper presents a line commutated converter (LCC) based multi-terminal HVDC transmission (MTDC) system feeding very weak AC networks with hybrid reactive power compensators (RPC’s) at the inverter AC side. The hybrid compensator is accomplished by the equal mixing of any two of the following compensators: synchronous compensator (SC); static var compensator (SVC); static synchronous compens...

Power factor correction is vital in present society. The two key benefits of power factor correction, which includes reduced power costs and higher system capacity. Implementation of Flexible AC Transmission Systems (FACTS) improves the power factor, power transfer capability and voltage stability. The shunt type of FACTS controller is used to either absorb or inject VARs into the system, there...

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.
