Comparative analysis of household consumers electroreceivers modes

Данная статья предлагает сравнительный анализ различных режимов работы бытовых электроприемников, на основе измерений, сделанных в реальной квартире. Измерение Показателей качества электроэнергии (ПКЭ) и снятие графиков нагрузки осуществлялось с помощью прибора регистратора-анализатора ПКЭ ChauvinArnoux СА 8335+. Ежедневные нагрузки и ежедневные затраты энергии рассчитаны и отображены графически с почасовой дискретностью. Выбраны наиболее эффективные способы регулирования потребления энергоресурсов и сокращения финансовых затрат на электроэнергию.The paper deals with the comparative analysis of various operating modes of household consumers electroreceivers on the basis of measurements in real apartment. Measurement of Unified Power Quality Index (UPQI) and reading load curves were accomplished by means of the UPQI logger Chauvin Arnoux СА 8335+. Daily load and daily cost of energy are calculated and shown graphically with hourly discretization. The most effective ways of regulation the energy consumption and reduction of financial expenses on the electric power are chosen

Research of household consumers electroreceivers modes

Ежемесячно потребители в квартирах платят за электроприборы в соответствии с потребляемой ими энергией. Данная статья представляет собой описание первых шагов, направленных на развитие и оптимизацию режимов распространенных бытовых устройств, и, как результат, и на финансовые расходы потребителей. Прежде всего, электрические приборы были разделены на 3 группы в соответствии с их режимами работы. Холодильник как представитель группы приборов резко переменной нагрузки, был выбран для основных измерений. Измерение Показателей качества электроэнергии (ПКЭ) и снятие графиков нагрузки осуществлялось с помощью прибора регистратора-анализатора ПКЭ Chauvin Arnoux СА 8335+. Анализ кривых нагрузки и графика расхода средств позволяет рассчитать финансовые затраты в процентах. Эти исследования могут стать основой для дальнейшего исследования в области уменьшения и оптимизации расходов.In modern world each of us has a range of electric appliances, which simplified our daily life, in our house or flat. But what is more all of us are obligated to pay for work of all devices, which means for power they consume. This paper represented first steps aimed to develop and optimize modes of common household devices and as a result our financial expenses. At first all electric appliances were shared to 3 groups according with their modes. Then refrigerator, as a representor of abruptly variable load group, was chosen for main measurements. Measurement of Unified Power Quality Index (UPQI) and reading load curves were accomplished by means of the UPQI logger ChauvinArnouxСА 8335+. Provided load curves and flow chart of funds allow to calculate financial expenses in percent. This research formulates base for following investigation in field of consume and expense optimization

Power Flows and Losses Calculation in Radial Networks by Representing the Network Topology in the Hierarchical Structure Form

This paper proposes a structured hierarchical-multilevel approach to calculating the power flows and losses of electricity in radial electrical networks with different nominal voltages at given loads and voltages of the power source. The researched electrical networks are characterized by high dimensionality, dynamism of development, but also insufficient completeness and reliability of state information. The approach is based on the representation of the initial network graph in the form of a hierarchical-multilevel structure, divided into two stages with rated voltages Unom ≤ 35 kV and Unom ≥ 35 kV, and using the traditional (manual) engineering two-stage method, where the calculation is performed in a sequence from bottom to top (stage 1) and from top to bottom (stage 2), moving along the structure of the network. The application of the above approach makes it possible to obtain an algorithm for implementation on a computer, which is characterized by universality (for an arbitrary configuration and complexity of the network), high performance and low requirements for the computer memory. © 2022 by the authors.
