Quality Of Electric Power

One of the keys of enhancing the quality of electric power supply resides in the accuracy of the consumption metering. Nowadays development of the sensors, devices and systems for electricity metering offers the basis for this service. Nevertheless, this achievement in many situations is altered such that appropriate measures must be adopted even if already significant costs have been registered. In this paper is proposed and discussed an optimal solution based on the identification and minimizing the measurement errors for increasing the electricity readings accuracy and lowering the electricity losses and related costs. In this regard, a mathematical model was developed and a particular algorithm for the mentioned problem is proposed and tested in the case of a power distribution company where an enhancement on average of the own technological consumption with 4% was recorded.

The article deals with the concept of solar photovoltaic systems use in power supply systems. An analysis of local solar resources potential has been carried out, and optimal orientation points of radiant heat absorbing photovoltaic panels have been chosen to achieve maximum energy performance. Simulation of electric power systems having different configurations has been implemented using the software program Homer. It has been stated that a combination of solar and diesel energy systems is considered to be an optimal solution under the weather conditions of Montenegro. The systems working together make it possible to reduce maintenance costs significantly and adjust capacity generation schedule with due account for energy consumption features to a maximum extent. This allows generating electric power at less cost and results in a more reliable and continuous power supply without failures for a consumer chosen.

Power Problem

Nigeria as a nation has suffered a lot when it comes to the availability of electricity. A clear comparison between this nation’s electric power supply and other countries revealed the present incessant electric power supply in the country. The average power per capital (watts per person) in the United States is 1,377 Watts. In Canada, it is as high as 1,704 Watts per person and in South Africa; it is 445 Watts per person. The average power per capital in Australia is 1,112 Watts and in New Zealand it is 1,020 W per person. Whereas, the average power per capital (watts per person) in Nigeria is 14 W person. The power system structure is characterized with a lot of faults and outages. These electric power problem has destroyed the industrial processes in the country. As a result, unemployment has increased in the country. As at February, 2020, according to the Federal Government of Nigeria, the number of unemployed youths in the country is 23 million. Data from the International Transparency in the United State stated that there are 40 million unemployed youths in the country. This has increased crime rates among the youths. The country experience a high level of hardship, insecurity and socio-economic disorder as results. Therefore, there is an urgent need to solve this incessant supply of electric power in the country. Hence, a detail study of Akure132/33kV substation Network of the Benin Electricity Distribution Company under which there are 84,264 customers was carried out.

Autonomous AC electricity supply systems are now widely introduced in agriculture. As the experience of operation of these electricity supply systems has shown, their various properties, determined largely by the type of voltage regulators and sensors used, do not always fully meet the constantly growing requirements for the quality of electricity. Further improvement of voltage regulation systems, and, consequently, the quality of electricity, is associated with the use of technology in them that can implement optimal control laws.

AbstractThe aim of the present work is to evaluate the power quality (PQ) required in individual customers in low voltage (LV), along an electrical circuit of 13.8 kV, in a distribution network standardized in urban area and with diversity of energy consumption profiles. Energy, including comprehended parts of the region with downside against financial rates. The data is useful in this sales environment of a Brazilian distribution company. These data were developed by the data mediation systems for a communication interface that enable to identify and evaluate PQ disturbance. The results of the surveys is compared with limits reported in Module 8 of the National Electric Energy Distribution Procedures (PRODIST), according to Brazilian Regulation Agency (ANEEL), that is, the pre-definition of rules, standards, parameters, and procedures about the quality of electric power supplied and the quality of the service provided. The PRODIST Procedure has a major analysis focused in the voltage supplied. The data sensors are based on studies of Duration Relative of Predary Stress (DRP) and Duration Relative of Transgression for Critical Stress (DRC). In this paper the results are presented and the challenged to supply this area with diversity of consumer profiles is commented.

<p>A Constituição de 1988, além de marco da redemocratização brasileira, institucionalizou a participação da sociedade nas ações do Estado, o que também foi sendo aperfeiçoado com a legislação posterior a 1988, paralelamente à profissionalização da Administração Pública e ao desenvolvimento do campo de públicas. Este trabalho aborda especificamente os Conselhos de Consumidores de Energia Elétrica, instituições participativas que representam os interesses coletivos dos consumidores de energia. No setor elétrico, os Conselhos exercem a função de examinar questões ligadas ao fornecimento de energia elétrica ao consumidor final. Tal papel pode ser desempenhado por meio da participação em audiências públicas realizadas pela ANEEL, de forma a auxiliar na formulação de atos normativos, permitindo ao Regulador analisar os impactos de suas propostas sob a ótica do consumidor antes da tomada de decisão. O trabalho pretende demonstrar a evolução nessa participação ao longo dos últimos anos, evidenciando a consolidação desse instrumento da democracia participativa.</p><p> </p><p>The 1988 Constitution, as well as the framework of the Brazilian redemocratization, institutionalized the participation of society in the actions of the State, which was also perfected with legislation after 1988, in parallel with the professionalization of the Public Administration and the development of the public policies field.

The estimated billing system for electricity was introduced in Nigeria by the Nigerian Electricity Regulatory Commission (NERC) in 2012 for billing customers without meters or with faulty or inaccessible meters. But instead of following the guidelines and formula provided by NERC for the estimation, the electricity Distribution Companies (DisCos) resorted to billing these customers arbitrarily and frustrated efforts by NERC to ensure the proper metering of electricity consumers. This research evaluates the incentive, which makes the DisCos in Nigeria prefer the estimating billing system to a much more efficient smart prepaid metering system. To carry out the research, four Enugu Electricity Distribution Company (EEDC) customers were selected. The estimated bills of these customers, which they received before they got smart prepaid meters, were compared with their prepaid meter bills for an equal period. EEDC was found to be over-billing these customers under the estimated billing system by a yearly average per customer of 64,901.67 Nigerian Naira (170.79 USD).
