Sophisticated loads require electric power of excellent quality. The research related in this article is about the electric power feeding a medium size Electron Accelerator, as well as Biotechnology, Nanotechnology and Bio Energy labs installed in Campinas, Brazil. Utility distribution line passes in places with great quantity of trees which causes faults during strong winds or rains, stopping the...
The connection of distributed generation (DG) to weak distribution networks is likely to cause voltage rise problems. At present, the voltage rise is usually mitigated by reinforcing the network but as the penetration level of DG increases also active voltage control methods need to be taken into use. Active voltage control has been a subject of extensive research in the past decade but the number...
Now days the Distribution Network Organizations (DNO's) have set some rules to maintain the voltage at a specified level to control the increase of voltage variations and controls the power factor. The main objective of this paper is that in cases of weak networks the voltage level is maintained by the distributed generation (DG) by importing or exporting active and reactive power. To control the...
The increasing demand of electrical power and continuous depreciation of conventional energy resources like oil, gas and coal, have facilitated the researchers to think over distributed electricity generation and consumption from the renewable sources like mini/micro hydro, biogas, wind etc., Three-phase self excited induction generator (SEIG) seems to be a prospective player for generation of low...
The paper present control scheme and investigates dynamic operation of static synchronous compensator (STATCOM) in both inductive and capacitive mode based on model comprising a full 48-pulse GTO voltage source converter for combined reactive power compensation and voltage stabilization of the electric grid network. The key STATCOM device is power electronic GTO converters connected in parallel with...
Increasing penetration of Distributed Generation (DG) in distribution networks significantly changes both the real and reactive power flows in the network and can create serious voltage control problems. Furthermore, traditional Automatic Voltage Control (AVC) schemes that can normally deal with the reverse power flows, are unable to cope with the voltage problems associated with the presence of DG...
This paper addresses the problem of voltage rise mitigation in distribution networks with distributed generation. A distributed automatic control approach is proposed to alleviate the voltage rise caused by active power injection. The objective of the proposed approach is not to control bus voltage but to guarantee that generator injections alone do not cause significant voltage rise: a solution in...
