This paper presents a methodology and software for simulating alternatives and works to amend voltage levels provided to affected low voltage customers. The methodology describes a type of state estimation of a low voltage network, using voltage measurements of a single load point. From a set of possible alternatives to amend voltage levels, the main is to install the Portable Voltage Regulator for...
This paper presents a methodology that defines the most suitable configurations to allocate reclosers in power distribution networks. The methodology is composed by two stages. At the first stage, optimal configurations to install reclosers in each feeder are established, considering the improvement promoted in continuity indexes. Each configuration corresponds to a previously fixed number of reclosers...
This article focuses on the developing of a Portable Voltage Regulator for Low Voltage Networks (PVRL VN), for single phase, two phases and three phases networks, which envisages meeting the regulations, given that the time established by the regulatory standards is a factor that limits the planning and the execution of corrective actions. The first PVRLVN was developed inside a Research & Development...
The phenomena related to Power Quality, as the voltage dips, imbalances, harmonic distortion and interruptions can cause damage to equipment used in industries and commercial sector. As soon as an outage occurs caused by one of these phenomena, there may be costs of various kinds, like production lost and others. Although there are mechanisms of cost internalization, such as penalties, the real cost...
This paper describes the development of a Portable Voltage Regulator for Low Voltage Networks applications (PVRLVN) that aims keeping consumers feeding voltage within the limits set by Brazilian Regulations Agency (ANEEL). PVRLVN allows adjusting grid voltage by means of the addition or subtraction of the adequate amount of voltage through an isolated secondary winding of a Buck-Boost transformer,...
